中文摘要：
西北内陆河流域,气候干旱,降水稀少,蒸发量大,水资源极其宝贵,生态环境脆弱。然而,西北内陆河流域工农业用水却存在不同程度的浪费现象,致使流域水资源管理出现诸如上下游利用不公,工农业利用不均等许多问题。现在,如何科学合理地优化配置西北内陆河流域水资源,并使其可持续利用,发挥最大的经济、社会和生态效益,已经成为学界和政界关注的重大问题。本文以石羊河下游流域民勤县为例,通过分析和研究流域水资源利用现状,提出了适合西北内陆河流域水资源优化配置的支撑体系,以期对本流域水资源可持续利用有所裨益。
英文摘要：
In the Inland River Basin,which the climate is arid,the water resources are scarce,the rainfall is exiguity,meanwhile water resources is wondrously invaluableness and the ecological environment is fragile.However,water consumption of industry and agriculture is not be limited,which causing many problems on water management,such as usage injustice on upper and lower reaches of basin,use inequality of other industrial and agricultural water resources.At present,it has been being one of important problems how to optimize and allocate water resources scientifically,make it sustainable and maximize its economic,social and ecological benefit.This paper takes Minqin as example which locates Shi-yang river lower reaches.By analyzing and studying present situation of the water resources usage,it proposes its supporting system which is suitable for optimizing and allocating water resources of inland river basin in Northwest of China in order to help sustainable use of water resources in the inland river basin.
