摘要：

Many researches on optimal allocation of water or land resource have been done at present, bnt few attention was paid to the combination of these two factors based on ecosystem. In this research, based on continuous 30-year weather condition report data, 10-year soil water content data and nearly 50-year hydrographic data in Yanhe watershed, and with remote sensing and GIS spatial analysis, the minimum, moderate and maximum ecological water requirement for land resource system were investigated. Additionally, with GLP (Gray Linear Programming) model, the allocation modes of water and land resources were put forward based on ecosystem which aimed at satisfying the ecological water requirement for land resource system and maximizing the ecosystem service value. The purpose of all above efforts was to offer a method for using water and land resources in effect, protecting ecosystem as well as developing social economy. By using GLP model, the constraints equations were established for satisfying ecological water requirement and the objective functions for realizing the coordinate and sustainable development in ecology and economic. The results showed that with the increase of water resources supply, the fruit industry was developing well, and the urbanization process was accelerating. It can be expected that from 2010 to 2030, the forests, shrubs and garden land will increase from 1264.49, 1201.51, 412.87 km2 to 1 504.32, 1434.67, 589.24 km2, and the construction land will increase from 346.73 to 575.38 km2, when satisfying the minimal ecological water requirement.
