Abstract：To explore the most appropriate optimal allocation of soil and water resources in the water source of Beijing, Huairou reservoir watershed, located in Beijing mountains area, was selected as study object. Based on five satellite images of the study region(1990、1995、2000、2005and 2008), spatio-temporal evolution of land use from 1990 to 2008 were obtained. Linear programming of grey parameters and CLUE-S model, based on ecosystem services value theory, were applied to optimize the allocation of land use of the watershed. The results showed that the eco-service value after the optimal allocation were significantly larger than those in 2008, increased by 17.954 million yuan at a growth rate of 5.4%. Among them, the value of water conservation had the most change, with an increase of 5.609million yuan. The value of purify atmospheric got the largest growth rate, which reached 9.3%.The results can provide a scientific reference for sustainable utilization, development and management of land and water resources in this region.
