Rural residents’ perception is an important way of evaluating rural ecosystem services. Different topographies affect the level of ecosystem services, thus affecting residents’ perceived preferences. This study conducted a questionnaire survey of 1176 rural residents in mountainous, hilly, and plain areas of Shandong Province. It analyzed respondents’ satisfaction with ecosystem services and landscape preferences in different topographical areas. The results showed that the perception of ecosystem services was higher than average in all three topographic areas. The perceptions from high to low were cultural services, provisioning services, and regulating services. The perception of ecosystem services was significantly affected by topography, with significant differences between mountainous and plain areas in particular. Rural residents’ perceptions of cultural services varied widely and there were diverse preferences. This study believes that the important concerns in enhancing the perception of ecosystem services among rural residents are to raise villagers’ ecological awareness by meeting their growing spiritual needs and the high sensitivity of older people.

Conversion of curtilage land into cropland or grassland can have substantial effects on soil nutrition and microbial activities; however, these effects remain ambiguous. This is the first study to compare the soil organic carbon (SOC) fractions and bacterial communities in rural curtilage, converted cropland, and grassland compared with cropland and grassland. This study determined the light fraction (LF) and heavy fraction (HF) of organic carbon (OC), dissolved organic carbon (DOC), microbial biomass carbon (MBC), and the microbial community structure by conducting a high-throughput analysis. Curtilage soil had significantly lower OC content, the DOC, MBC, LFOC and HFOC of grassland and cropland soils were 104.11%, 55.58%, 264.17%, and 51.04% higher than curtilage soil averagely. Cropland showed notably high bacterial richness and diversity, with Proteobacteria (35.18%), Actinobacteria (31.48%), and Chloroflexi (17.39%) predominating in cropland, grassland, and curtilage soil, respectively. Moreover, DOC and LFOC contents of converted cropland and grassland soils were 47.17% and 148.65% higher than curtilage soil while MBC content was 46.24% lower than curtilage soil averagely. Land conversion showed more significant effects on microbial composition than land-use differences. The abundant Actinobacteria and Micrococcaceae population and the low MBC contents indicated a “hungry” bacterial state in the converted soil, whereas the high MBC content, Acidobacteria proportion, and relative abundance of functional genes in the fatty acid and lipid biosynthesis indicated a “fat” bacterial state in cropland. This study contributes to the improvement of soil fertility and the comprehension and efficient use of curtilage soil.

Due to the changes in land use types and industrial agglomeration brought by the long-term rapid urbanization, the ecology of China’s rural areas has been greatly impacted. The health of residents and other living beings living in rural areas has been affected. In recent years, the ecology of the rural environment has been paid attention to. This study performed a bibliometric analysis of 167 papers on the Web of Science from 2013 to 2022. It shows that policy management and environmental science were two main research fields in solving the ecological and environmental crisis in China’s rural areas. Additionally, it was found that the study areas often spanned administrative districts, and the research was mainly based on the integrity of the overall ecosystem. The cases studied were mainly distributed in the following three types of areas: continuous river basins and lake basins; economically developed regions; and less developed areas with relatively fragile ecosystems. Ecological elements such as water, soil, air, and vegetation were all included in the study aims. Finally, from the perspective of institutional reform, comprehensive approaches to solving China’s rural ecological environmental problems in the current research were identified, including the revision of laws and regulations, economic means, technological innovation, and public participation.

The Qi Great Wall is one of China’s earliest surviving linear cultural heritage corridors, and its surrounding rural areas play a dual role in heritage conservation and tourism development. However, the corridor has received limited attention in tourism and rural research, facing challenges of fragmented development. This study focuses on rural areas along the Qi Great Wall and develops a comprehensive analytical framework integrating multidimensional evaluation, obstacle degree analysis, and development typology to assess rural tourism development levels across the 15 corridor sections, identify their major constraints, and formulate differentiated development strategies. The results reveal substantial spatial disparities in rural tourism development, with a general west-to-east decline. Tourism resources constitute the primary constraint, followed by tourism reception facilities, transportation facilities, and infrastructure and public services. The 15 sections are classified into four types, namely strong node led, service quality optimization, destination identity cultivation, and support capacity enhancement, providing a basis for targeted and differentiated interventions. The findings have practical implications for rural tourism planning and coordinated heritage conservation along the Qi Great Wall, and the analytical framework offers methodological insights transferable to other linear cultural heritage corridors.
