Spatial Heterogeneity of Driving Factors of Wind Erosion Prevention Services in Northern China by Large-Scale Human Land-Use Management

Large-scale human land-use management is an effective method for ecosystem restoration and wind erosion prevention service (WEPS) improvement. However, the spatial differences of driving factors and the feedback in subsequent management have received less attention. This study analysed the temporal and spatial changes in the WEPS in northern China from 2000 to 2015, classified the driving modes between the WEPS and environmental factors, distinguished the main driving factors, and proposed suggestions for successive projects. The results showed that, compared with 2000, the amount of WEPSs in 2015 increased by 12.60%, and forest and grassland in the WEPS-increased area was 1.34 times that in the declining area. There were east-west differences in the driving mechanism of WEPS improvement. In addition to climatic and topographic factors, the western division was mainly affected by changes in vegetation quality, whereas the eastern division was affected by the combined influence of vegetation quality and quantity. This study shows the necessity of land-use management and project zoning policies, and provides a reference for policy formulation and management of large-scale ecological projects.
