Soil conservation services can weaken and improve soil erosion, and by analyzing its spatial distribution characteristics and influencing factors, it can improve soil conservation capacity and reduce regional soil erosion. This paper firstly estimates the amount of soil erosion in the study area based on the RUSLE model and the InVEST model, and then selects a soil erosion estimation model with higher accuracy to evaluate the soil conservation service in the study area. The main factor of spatial distribution. The results show that: 1) The difference between the estimated results of the RUSLE model and the actual soil erosion modulus in the study area is 201.02 t/(hm²?a), which is of low precision. The difference between the estimated results of the InVEST model and the actual soil erosion modulus in the study area is 33.11 t /(hm²?a), with high precision; 2) The total soil conservation in the study area is 13.01×108 t, and the areas with stronger soil conservation ability are in the northeast and southwest of the study area, while the soil in the west, central and southeast of the study area is The retention capacity is weak; 3) The climatic factors affecting soil conservation services are mainly precipitation and temperature, and the landscape indices affecting soil conservation services are mainly sprawl index, landscape segmentation degree, separation index and Shannon uniformity index. The research results can provide a scientific basis for the sustainable development of ecosystem services.
