Based on the detailed survey of land use change in Shiyang river basin, referencing Costanza, and Xie et al’ research results of the value of ecosystem services, this article probed the variation of land use and value of ecosystem service in Wuwei region. The results are: from 1997 to 2006, the area of woodland, construction land and garden land are increasing, while farmland, grassland, water and unused land are continuing to decrease. Land-use intensity is gradually increasing, the land use pattern towards to a centralized style. The values of ecosystem services are overall upward, and change faster than ever. The main part of the value of ecosystem service is constituted by the value of grassland, woodland and farmland. So it’s important to control the expansion of urban construction, strength the protection of the water, restore and enhance regional ecosystem services in the future.
