Numerous methods have been used in the spatial prediction of soil salinity. However, the most suitable method is still unknown in arid irrigation regions. In this paper, 78 locations were sampled in salt-affected land caused by irrigation in an arid area in northern China. The geostatistical characteristics of the soil pH, Sodium Adsorption Ratio (SAR), Total Salt Content (TSC), and Soil Organic Matter (SOM) of the surface (0–20 cm) and subsurface (20–40 cm) layers were analyzed. The abilities of the Inverse Distance Weighting (IDW), Ordinary Kriging (OK), and CoKriging (CK) interpolation methods were compared, and the Root Mean Square Error (RMSE) was used to justify the results of the methods. The results showed that the spatial distributions of the soil properties obtained using the different interpolation methods were similar. However, the surface layer exhibits more spatial heterogeneity than the subsurface layer. Based on the RSME, the nugget/sill value and range significantly affected which method was the most suitable. Lower nugget/sill values and lower ranges can be fitted using the IDW method, but higher nugget/sill values and higher ranges can be fitted using the OK method. These results provide a valuable reference for the prediction of soil salinity.

In this study, 152 undisturbed soil samples from the 0–10 cm and 10–20 cm soil depths along two transects across the Taihang Mountain Region in northern China were investigated. The effect of soil properties (bulk density (BD), capillary porosity (CP), non-capillary porosity (NCP), soil organic carbon (SOC), and sand, silt, and clay contents) and environmental properties (land use type, topographical location, and elevation) on the Ks was determined. Moreover, the direct and indirect effects of these factors on the Ks were determined using the structural equation modeling (SEM). The results show that the Ks of the 0–10 cm soil depth (4.48 m/d) is significantly (p < 0.05) higher than that of the 10–20 cm soil depth (3.31 m/d), suggesting more rapid infiltration in the surface soil depth. The coefficients of variance (CVs) are 0.75 and 1.03 for the surface and sub-surface depths, respectively, indicating moderate and strong variations in the Ks in the two depths. The SEM revealed that most of the effects of the environmental properties on the Ks are indirect, accounting for 80.5% and 90.9% of the total effect in the surface and sub-surface soil depths, respectively. This demonstrates that the composite soil property was the direct, but the composite environmental property was the indirect factors influencing the Ks. These results deepen our existing understanding of the factors controlling the Ks in mountainous regions.

Our study area is the upstream watershed of the Guanting and Miyun Reservoirs; together, these two reservoirs comprise the main drinking water source of Beijing, China. In order to prevent crop contamination and preserve the quality of the water and soil, it is important to investigate the spatial distribution and the sources of the heavy metals in farmland soils on the watershed scale. For this study, we collected 23,851 farmland surface soil samples. Based on our analysis of the concentrations of eight heavy metals in these samples, we found that the overall soil quality in our study area is excellent, but that the Cd, Cu, Zn, and Cr contamination risks are relatively high. Moreover, a percentage of samples exceeded the Cd (1.54%,), Cu (0.28%), Zn (0.25%), Cr (0.13%), Pb (0.09%), As (0.05%), Ni (0.04%), and Hg (0.02%) risk screening values for soil contamination in agricultural land. In addition to determining the spatial distribution characteristics of the heavy metal concentrations of the soil samples, we also conducted a factor analysis and an R cluster analysis (CA) whcih can gathered the similar variables to track the sources of the heavy metals. We found that the Cd, Pb, and Zn are likely sourced from a quartz syenite porphyry body and from coal-fired enterprises, while the Cr, Cu, and Ni contaminations are mainly caused by runoff from iron ore smelting. Additionally, agricultural production contributes to the local accumulation of Cu, and industrial (smelting) discharge is partially responsible for the As contamination. As a result of the atmospheric deposition of pollutants, areas with high Hg concentrations are generally centered on large- and medium-sized cities. Due to these high natural heavy metal background values, the existing and future heavy metal contamination in the watershed poses a serious ecological risk to both the soil and the surface water.

The Earth’s climate has warmed by approximately 0.6 °C over the last century, but temperature change in the Taihang Mountain region—an important transition zone in North China which functions as an ecological barrier for Beijing, Tianjin, and other big cities—is still unknown. In this study, we analyze the spatial and temporal trends in the average annual and seasonal surface air temperature in the Taihang Mountain region from 1968 to 2017. The effect of elevation, longitude, latitude, percent forestland, percent farmland, and gross domestic product (GDP) on temperature was also determined. Our results show that the Taihang Mountain has warmed by 0.3 °C/decade over the past five decades. Partitioned seasonally, average warming was 0.38, 0.14, 0.21, and 0.47 °C/decade in spring, summer, fall, and winter, respectively. Elevation and latitude were significantly negatively correlated with temperature but had no correlation with the temporal warming trend (i.e., the Z value from a Mann–Kendall test). The Z value was significantly negatively correlated with percent forestland and positively correlated with GDP, indicating that economic development has induced warming, but afforestation may reduce the rate of warming increase. Together, our results provide important insights into the rates and drivers of climate change within mountainous regions.

Spatial–temporal variations in precipitation significantly influence infiltration, runoff, and other hydrological processes; and thus, in turn, they influence the risk of natural disasters such as flooding, drought, and erosion. Knowledge of these processes is still limited in the Taihang Mountain region, which is a highly heterogeneous environment in northern China. In this study, annual precipitation data for 1968–2017 from 88 weather stations in the Taihang Mountain region were analyzed. The Mann–Kendall (M–K) test and precipitation-related indices (precipitation amount, Sen’s slope, Precipitation Concentration Index (PCI), and Coefficient of Variation (CV)) were used to analyze the spatial and temporal trends in precipitation in this region. Nine predictors (elevation, longitude, latitude, slope gradient, slope aspect, maximum temperature (Tmax), minimum temperature (Tmin), difference between Tmax and Tmin (DT), and evapotranspiration (ET)) were used to predict the precipitation and the related indices. The results reveal that the annual precipitation generally decreased from 1968 to 2017, but the M–K test indicates a nonsignificant trend. The precipitation decreased from southeast to northwest with significantly different spatial variations over the five decades investigated. The decrease in the PCI was not significant, and it generally decreased from northeast to southwest, suggesting a higher risk of flooding and drought in the northeast. The CV was 0.18–0.32, indicating a moderate spatial variation. In addition, the CV slightly decreased during the 50 years investigated. Multiple linear regression revealed that the amount of precipitation could be predicted from the latitude and longitude. The slope trend could be predicted based on latitude. PCI could be predicted based on longitude and elevation. CV could be predicted based on elevation, longitude, and Tmax. This suggests that the precipitation was mainly influenced by the geographical factors in the Taihang Mountain. This is useful information for the prediction of precipitation and for water management in this mountain region.

Loss of pedodiversity is a worsening land degradation issue worldwide. Knowledge of rare and endangered soils is critical for the protection of pedodiversity. However, such knowledge remains limited, especially for mountain regions with intensive human disturbance. In this paper, rare and endangered soils were identified using the Harmonized World Soil Database (HWSD), and their spatial distributions determined for Taihang Mountain region, North China. Furthermore, the effects of natural (elevation, precipitation, temperature, slope gradient, soil parent and vegetation) and human (farming and population density) factors on rare and endangered soils were analyzed. The results showed that based on the second level HWSD classification, a total of 94 soil types were identified in Taihang Mountain region, 36 of which were rare and 7 endangered soils. It implied that there was the need to protect soil resources in this region. Cluster analysis showed that Dystric Podzoluvisols and Mollic Gleysols were the most endangered soils in terms of both area and distribution, suggesting that these soil types needed to be protected. Most of the rare and endangered soils were distributed in the northern of Taihang Mountain, indicating that the northern part needed more attention. Correlation analysis showed that the effect of human factors on rare and endangered soils was more important than that of natural factors, confirming that human activities were largely responsible for the occurrence of rare and endangered soils. Such results provided not only further understanding of pedodiversity, but also useful information for protection of soil resources and control of land degradation.

Calcium and magnesium are related to the structure and functions of soil, especially the saline alkali soil. This study aimed to explore calcium element and magnesium element concentration and accumulation in relation to salt ion uptake and soil quality. The two elements in plant organs were studied for six oat varieties at four growth stages. The results showed that calcium element concentration and accumulation across plant organs ranged from 3.4 to 12.1 g kg−1 and 2.6 to 6.3 kg ha−1 while those for magnesium element ranged from 1.7 to 5.3 and 1.5 to 3.3. Among varieties, the concentrations and accumulations varied significantly. Significant variations also occurred among the four growth stages with a peak at delayed harvest stage. However, the highest accumulation occurred at maturity. The ratio [calcium element/magnesium element] increased from elongation (heading stage) (1.2 to 1.9 times) to delayed harvest stage (2.9 to 3.2 times). A significant (partial) positive correlation was found among concentrations of calcium, magnesium, chlorine, potassium elements and sodium. The prospect of using oat treated with calcium and magnesium fertilizer to reduce soil alkalinity should be studied further.

The regulation and management of ecosystem services are fundamental for sustainable development in mountain areas. Although no obvious vertical band spectrum exists in Taihang Mountain region, vertical differentiation of ecological characteristics in the region is obvious. The ecosystem characteristics of vertical differentiation were analyzed using 4 typical ecological indices (land use, temperature, net primary productivity, and water yield). The ecosystem service functional pattern was determined based on analysis of the ecosystem services value per unit area. The 2 ecosystem critical zones of vertical differentiation (500–600 m and 1400–1500 m) were determined. The mountain area was divided into 3 ecological zones—sub-alpine zone (>1500 m), mid-mountain zone (600–1400 m) and hilly zone (<500 m). The ecosystem services functional pattern was as follows: provisioning services was the main ecosystem services function in the hilly zone, 4 ecosystem service functions were equally important in the mid-mountain zone, regulating, supporting and cultural services were the main ecosystem service functions in the sub-alpine zone. The model of ecosystem service regulation and management in 3 ecological zones was built based on the functional patterns to promote sustainable development.

Managing the rapidly changing saline-alkali land under cultivation in the coastal areas of China is important not only for mitigating the negative impacts of such land on the environment, but also for ensuring long-term sustainability of agriculture. In this light, setting up rapid monitoring systems to assist decision-making in developing sustainable management plans is therefore an absolute necessity. In this study, we developed a new interpretation system where symbols are used to grade and classify saline-alkali lands in space and time, based on the characteristics of plant cover and features of remote sensing images. The system was used in combination with the maximum likelihood supervised classification to analyze the changes in cultivated lands under saline-alkali conditions in Huanghua City. The analysis revealed changes in the area and spatial distribution of cultivated under saline-alkali conditions in the region. The total area of saline-alkali land was 139,588.8 ha in 1992 and 134,477.5 ha in 2011. Compared with 1992, severely and moderately saline-alkali land areas decreased in 2011. However, non/slightly saline land areas increased over that in 1992. The results showed that the salinization rate of arable lands in Huanghua City decreased from 1992 to 2011. The moderately saline-alkali land southeast of the city transformed into non/slightly saline-alkaline. Then, severely saline-alkali land far from the coastal zone west of the city became moderately saline-alkaline. Spatial changes in cultivated saline-alkali lands in Huanghua City were such that the centers of gravity (CG) of severely and non/slightly saline-alkali land moved closer the coastline, while that of the moderately saline-alkali land moved from southwest coastal line to northwest. Factors influencing changes in cultivated lands in the saline-alkali ecosystem included climate, hydrology and human activity. Thus, studies are required to further explore these factors in order to build a better understanding into the relative contributions of the changes saline-alkali state on the functions of coastline ecosystems.

The North China Plain (NCP) is one of the most productive and intensively cultivated agricultural regions in China but it experiences severe water shortages; thus field irrigation relies heavily on groundwater. The extraction of groundwater for irrigation has sustained increased grain yield, although the value of the irrigation water has not been estimated. Here, we propose an evaluation model for underground water used for irrigation, which took into account the infrastructure price, resource price and environment price based on monetary values. We classified underground water into total extracted, actual consumption and over-exploited water according to the hydrological cycle. We then performed a benefit-cost analysis of three underground water irrigation scenarios—actual irrigation, equilibrium irrigation and maximum water productivity (WP) irrigation—using the proposed model and Luancheng County of NCP as a case study. The results showed that (1) the volume of irrigation water varied in the order of actual irrigation scenario > equilibrium irrigation scenario > maximum WP irrigation scenario. The amount of different components of water—extracted groundwater, actually consumed groundwater and over-exploited groundwater- varied similarly, although the yearly variations in extracted groundwater were smaller; (2) the total water price should include the infrastructure price, resource price and environment price, although farmers merely pay for the infrastructure price; the resource price constituted the largest proportion of the total water price, especially in the dry years; (3) equilibrium irrigation was the most suitable scenario based on net benefits by our valuation method of underground irrigation water.

Exploring the relationship between different services has become the focus of ecosystem services research in recent years. The agro-ecosystem, which accounts for one-third of the global land area, provides lots of services but also disservices, depending on resources provided by other systems. In this paper, we explored the agro-ecosystem from four aspects: a summary of different indicators in the agro-ecosystem, input and output changes with time, relationships between different ecosystem services and disservices, and resource contribution to major services, using Luancheng County of North China as the study area. We then used emergy analysis to unify all the indicators. The conclusions were that the agro-ecosystem maintained provisioning and regulating services but with increasing volatility under continued growth in production inputs and disservice outputs. There was a positive correlation between most of the different services and disservices. Rainfall and groundwater resources were the most used input resources in the agro-ecosystem and all other major ecosystem services depended directly on them.

Oat is widely used as a food source in human and animal diets. In China, supplementary cultivation of oat has recently been extended into marginal saline soils, due to its extensive use. The goal of the present study was to explore and compare the agronomic characteristics, biomass production, and distribution of oat in coastal saline soil. A single-factor randomized block design experiment with six naked and husked oat varieties [Bayou-1 (BU-1), Baiyan-2 (BY-2), Baiyan-7 (BY-7), Huawan-6 (HW-6), Huazao-2 (HZ-2), and Pin-16 (P-16)] as treatments was conducted in the Hebei Province of China. The growth period (77 to 88 days) of the six oat varieties were shorter in saline soil than their original breeding region. Moreover, the plant was shorter, with a lower grain number per plant and seed setting. Grain weight increased and no change was observed in the floret number in coastal saline soil relative to the original habitats. The BY-7 variety produced the highest biomass value of 7.0 t ha−1 compared to the other five varieties. Compared with two active growth points, most varieties in the present study showed just one growth activity point between elongation and heading. Two fast growth periods for the six oat varieties were due to the high total leaf biomass growth rate (BGR) from elongation to heading and panicle BGR from heading to maturity. The biomass growth ratio (BGO) during elongation to heading was the largest among the four growth stages of the oat varieties. The number of kernels per spike decreased at the research site, but grain weight increased. Substantial differences were observed for growth periods, biomass, BGR, BGO, and other agronomic characters in the coastal saline soil of North China, but the BY-7 variety was the most suitable variety for the study site.

Improvement of saline-alkali soils by biological means is a strategic soil conservation method. To investigate the capacity of oat for phytoremediation, two factor randomized block design experiments are carried out in coastal North China. The two factors — oat variety (“Ba You-1” – BU, “Hua Zao-2” – HZ and “Bai Yan-2” – BY) and soil salinity (1.0, 2.0 and 3.0 g kg−1) — are analyzed for oat biomass, straw ion accumulation and straw-to-soil ion concentration ratio. Results show that oat biomass be affected by harvest time and soil salinity. BU biomass decreases by 0.4 t ha−1 for harvest delay by 20 days. And BY biomass drops severely which from 3.1 t ha−1 in low soil salinity to 0.4 t ha−1 in high soil salinity. The straw ion concentration (except Ca2+) significantly drops when harvest is delayed, but it increases with soil salinity increases though K+ concentration markedly decreases. For the straw ion accumulation, the highest value for harvest time is at maturity (146.4 kg ha−1 for BU) and for soil salinity is at low level (100.2 kg ha−1 for BY) and it turns sharp decrease with the time delaying and soil salinity increasing. Ions changes in stem significantly lower than that of in leaf whatever delay harvest time or increases soil salinity. Under medium soil salt concentration, the straw-to-soil total ion concentration ratios are respectively 31.7, 32.5 and 31.3 for BU, BY and HZ. The correlation analysis reveals that oat ion accumulation is positively correlated with biomass. Besides, straw Na+ and Cl− accumulation is respectively negatively (p < 0.05) correlated with K+. According to above that oat is a potential plant species in improvement of saline soil. However the low biomass and salinity tolerance limit its practical application in coastal saline-alkali soils North China.
