Abstract:The ecological environment restoration projects have played vital roles in protecting the watershed's environment and improving the ecosystem services. The Chaohe River Basin, located at the upstream of the Miyun Reservoir, was selected as the study area. According to the "13th Five-Year" Ecological Environmental Protection Plan for Chaohe River Basin, four scenarios were setup, including the fertilizer reduction, establishment of riparian buffer zone, Grain for Green Program, and integrated treatment method. The InVEST model was used to quantify the changes on ecosystem services and the direct and alternative market approaches were applied to estimate ecosystem services values under these four scenarios. The results have shown that ① All four scenarios have presented positive effects on the ecosystem services enhancement. ② Reduction of fertilizers and pesticides will reduce the phosphorous (13.14%) and nitrogen pollution (10.94%) not obviously. ③ The integrated treatment would increase the water yield, water purification (TP/TN reduction) and soil conservation services for 40.18%, 53.89%, 42.32%, and 63.76%, respectively. Accordingly, the integrated practices would also increase the ecosystem services value for 77.26 million yuan. This study has tried to introduce a practical approach for policy makers and stakeholders to evaluate the income of restoration practices and to find the best restoration practices for improving the ecosystem services function.
