摘      要：Guanting Reservoir（GR） is one of the most important water sources for Beijing and neighboring *** to water pollution,it was withdrawn from the system to supply Beijing drinking water;however,after a thorough treatment process,GR was made a reserve water source since *** develop a comprehensive and quantitative analysis of water yield and purification services in the GR watershed,this study selected two time periods：the period when GR was withdrawn from the system supplying local drinking water and the period that it has been designated a reserve water *** In VEST model was used to evaluate the quantities of water yields,and total nitrogen and total phosphorus outputs from 1995 to 2010 Additionally,the spatiotemporal variations of water yield services and water quality purification services in the GR watershed were *** results showed that water yield services in the GR watershed first weakened and then became stronger,but weakened overall during the years 1995 to *** yield capacity in the basin decreased from 1.89×10^9 m3 in 1995 to 1.43×10^9 m3 in 2010（a drop of 24.0% in total）.Water quality purification services also showed the same *** nitrogen output decreased from 4028.7 t in 1995 to 3611.4 t in 2010,while total phosphorus decreased from 379.7 t in 1995 to 354.0 t in *** and phosphorus purification services were enhanced by 10.4% and 6.8%,*** in the climate and land use were the main factors which lead to the changes in the water yield service in the GR *** intended to protect water resource have matched the varying trends of water quality purification services during different *** one hand,the research results provide a foundation to identify key fields for eco-compensation in the Guanting Reservoir *** another hand,the ecosystem service value will increase on the basis of eco-compensation criteria through setting the scenarios of returning farmland to forest and
