Abstract：A key problem is clarifying the relationship between compensation standard and the supply of additional ecosystem services in the study of ecological compensation.Focusing on the Gansu section of the Weihe River Basin，the specific target of ecological compensation is going to increase the soil conservation capacity.We will compensate people who have marginal farmland when the slope is more than 25°.Based on social and economic survey data and remote sensing data，we used minimum\| data approaches to simulate ecological compensation standards，then used InVEST model to simulate the results，analyze the potential of increased ecosystem service，and choose the best forest species after turn marginal farmland into forests.In the end，analyze additional ecosystem services in different compensation standards.The solution is that each county /district can select the best forest when turn marginal farmland of the slope is more than 25°，which can maximum add soil conservation quantity.Weiyuan County and Longxi County can plant evergreen coniferous forest，that newly add soil conservation quantity are 144×104 t and 63.04×104 t per hectare each year，the amount of compensation is 506.67×104 CNY and 686.7×104 CNY each year.The added soil conservation quantity is 1 152.00 t and 504.32 t in eight years.
