| 摘 要： | 根据民勤1999年以来水资源利用数据,结合GIS(Geographic Information System,GIS)空间分析和地统计学方法,研究了该地区地表水利用现状和地下水埋深的时空格局.在此基础上,采用WEAP(Water Evaluation and Planning System,WEAP)模型,从地表水来水量、压缩种植面积和调整种植结构3方面入手,设置多种水资源利用方案,以期找出水资源利用的优化模式,从而实现民勤的生态环境优化和可持续发展.

| Abstract: | According to the data of water resources in Minqin irrigated area since 1999,by using the meth- ods of GIS spatial analysis and Geostatistics, the existing state of surface water and the spatial-temporal pattern of groundwater were investigated. The WEAP model was used to evaluate and plan water utiliza- tion in the future from these aspects： the amount of surface water, compressed planting areas and adjusted planting structures. Our aim was to find the optimization modes,to repair the eco-environment of Minqin irrigated area and to achieve its sustainable development. |
