Soil conservation function is one of the important regulatory service function for ecosystems.Quantitative e-valuation of the spatial distribution characteristics of soil conservation function in Tianjun County can provide corresponding intellectual support for soil erosion prevention and ecological product value accounting in the region.Evaluate and study the soil conservation function of Tianjun County from the perspectives of material quality and value based on the universal soil e-rosion equation(RUSLE model).The results are as follows:(1)There is significant spatial heterogeneity in the spatial distribution of soil conservation in Tianjun County,showing an overall spatial distribution pattern of high in the northwest southeast and low in the central region;(2)The order of soil conservation per unit area for different land use types in Tian-jun County from large to small is:forest land,grassland,water and water facility land,construction land,wetland,and oth-er land;(3)The total amount of soil conservation in Tianjun County in 2023 is 3.28×105 t/a,and the total value of soil conservation is 20.48×105 yuan.Among them,the value of soil fertility preservation is 11.77×104 yuan;Reduce the value of sediment accumulation by 189.94×104 yuan;The economic value of reducing land abandonment is 30.63×103 yuan.
