Constructed wetlands can play an active role in improving the water quality of urban rivers. In this study, a sequential series system of the floating-bed constructed wetland (FBCW), horizontal subsurface flow constructed wetland (HSFCW), and surface flow constructed wetland (SFCW) were constructed for the urban river treatment in the cold regions of North China, which gave full play to the combined advantages. In the Yitong River, the designed capacity and the hydraulic loading of the system was 100 m3/d and 0.10 m3/m2d, respectively. The hydraulic retention time was approximately 72 h. The monitoring results, from April to October in 2016, showed the multiple wetland ecosystem could effectively remove chemical oxygen demand (COD), ammonia nitrogen (NH4+-N), total nitrogen (TN), total phosphate (TP), and suspended solids (SS) at average removal rates of 74.79%, 80.90%, 71.12%, 78.44%, and 91.90%, respectively. The removal rate of SS in floating-bed wetland was the largest among all the indicators (80.24%), which could prevent the block of sub-surface flow wetland effectively. The sub-surface flow wetland could remove the NH4-N, TN, and TP effectively, and the contribution rates were 79.20%, 64.64%, and 81.71%, respectively. The surface flow wetland could further purify the TN and the removal rate of TN could reach 23%. The total investment of this ecological engineering was $12,000. The construction cost and the operation cost were $120 and $0.02 per ton of polluted water, which was about 1/3 to 1/5 and 1/6 to 1/3 of the conventional sewage treatment, respectively. The results of this study provide a technical demonstration of the restoration of polluted water in urban rivers in northern China.

Small- and medium-sized rivers are facing a serious degradation of ecological function in water resource-scarce regions of Northern China. Reservoir ecological operation can restore the damaged river ecological environment. Research on reservoir ecological operation and watershed management of urban rivers is limited in cold regions of middle and high latitudes. In this paper, the urban section of the Yitong River was selected as the research object in Changchun, Northern China. The total ecological water demand and reservoir operation water (79.35 × 106 m3 and 15.52 × 106 m3, respectively) were calculated by the ecological water demand method, and a reservoir operation scheme was established to restore the ecological function of the urban section of the river. To examine the scientific basis and rationality of the operation scheme, the water quality of the river and physical habitat after carrying out the scheme were simulated by the MIKE 11 one-dimensional hydrodynamic-water quality model and the Physical Habitat Simulation Model (PHABSIM). The results indicate that the implementation of the operation scheme can improve the ecological environment of the urban section of the Yitong River. A reform scheme was proposed for the management of the Yitong River Basin based on the problems in the process of carrying out the operation schemes, including clarifying department responsibility, improving laws and regulations, strengthening service management, and enhancing public participation.

Habitat loss is a key factor affecting Siberian crane stopovers. The accurate calculation of water supply and effective water resource management schemes plays an important role in stopover habitat restoration for the Siberian crane. In this paper, the ecological water demand was calculated and corrected by developing a three-dimensional model. The results indicated that the calculated minimum and optimum ecological water demand values for the Siberian crane were 2.47 × 108 m3~3.66 × 108 m3 and 4.96 × 108 m3~10.36 × 108 m3, respectively, in the study area. After correction with the three-dimensional model, the minimum and optimum ecological water demand values were 3.75 × 108 m3 and 5.21 × 108 m3, respectively. A water resource management scheme was established to restore Siberian crane habitat. Continuous, area-specific and simulated flood water supply options based on water diversions were used to supply water. The autumn is the best season for area-specific and simulating flood water supply. These results can serve as a reference for protecting other waterbirds and restoring wetlands in semi-arid areas.

Since large areas of peatlands in China have been degraded or reclaimed to cropland in recent decades, the conversion of these croplands to wetlands and the restoration of degraded peatlands by means of engineering have been attracting increasing attention. Hydrologic mediation and plantation of dominant peatland species were implemented to determine the effects of these two artificial measures on revegetation and soil property improvement in paddy fields in the Changbai Mountains in Northeast China. The results showed that after a three-year restoration, compared to natural restoration treatment, planting of Carex schmidtii significantly reduced aboveground biomass by 45% (P < 0.05), increased root biomass by 53% (P < 0.05), increased the Shannon–Wiener Index by 17%, enhanced concentrations of total soil organic matter by 28% (P < 0.05), reduced topsoil bulk density by 40% (P < 0.05), and improved water retention capacity of the topsoil. These results demonstrate the ability of C. schmidtii to inhibit the growth of weeds and other nontarget species through competition, and to increase the amount of residual roots in soil due to its well-developed rhizomes. Aboveground biomass and total organic matter in hydrologic mediation were 38% lower and 37% higher than in the natural restoration treatment, respectively. However, annual precipitation in this area is 704.2 mm, higher than most other area in Northeast China, and the Shannon–Wiener Index and soil bulk density were 4% and 29% lower than in the natural restoration treatment, respectively. Furthermore, the combined application of these two measures resulted in 35% lower aboveground biomass, 22% higher Shannon–Wiener Index, 16% higher topsoil organic matter, and 27% lower bulk density than in the natural restoration treatment. However, the growth of C. schmidtii was inhibited due to the reduction in its survival rate and basal width growth rate. Our results suggest that planting C. schmidtii is an effective way to promote the restoration of degraded peatland and enhance its carbon sink function in the Changbai Mountains. On the other hand, implementation of hydrologic mediation is not recommended for this rain-rich region.
