Analysis of Spatial and Temporal Characteristics and Spatial Flow Process of Soil Conservation Service in Jinghe Basin of China

The supply and demand of ecosystem services their mutual feedback are important for the formulation basin ecological environmental policies. Simulation spatial flow can clarify division areas support policy development. This paper takes Jinghe Basin in Loess Plateau China as case-study area to simulate soil conservation service on different scales. results showed that (1) erosion situations improved overall, with a trend first aggravating then recovering between 2005 2015; (2) amount annual accounted more than 75% potential increasing decreasing; (3) using digital elevation model (DEM) data ArcGIS software, experiment divided into sub-basins (58 total) hydrological response units (HRUs) (e.g., 2181 HRUs sub-basin #1), which were used quantify direction corresponding “HRU—river-sub-basin” scale. helped pattern from HRU sub-basin.
