摘　　要：生态环境需水量是在特定的时间和空间条件下,为了维持和改善生态环境系统正常的生态结构与生态环境功能所需要的水资源量。从石羊河下游民勤绿洲的生态环境系统的特殊性和典型性出发,为维持和保护区域生态环境系统正常的生态功能,探讨区域生态环境需水量计算方法,并提出适合研究区的生态环境需水量计算模型,并对研究区域生态环境需水进行定量化计算,得出2000年民勤绿洲生态环境需水量为4.07×10^8m^3。Water demand of eco-environment is the needed water resources in the course of sustaining and improving the structure and the function of the eco-environment system.. On the base of the particularity and representative of the eco-environment system in Minqin oasis, in the lower reach of Shiyang river, to sustain and protect the basic function of the area eco-environment system, the calculation model of water demand of eco-environment is studied. This paper establishes a calculation model of water demand of eco-environment , which is adapted to the research area. Finally, water demand of eco-environment in Minqin oasis in the lower reach of Shiyang river is calculated, it is up to 4.07×10^8m^3.
