和田河流域耗水现状分析

和田河流域位于干旱内陆区,降雨稀少,蒸发剧烈,水量散耗是该地区水份运动的主要形式。本文采用和田绿洲散耗型水文模型,对流域耗水现状进行综合分析。分别从河流、水库、地下水、绿洲灌区的耗水水平,流域耗水的年内分配,社会经济与自然生态系统耗水比例等方面体现耗水现状,为和田河流域今后的水土资源合理配置与管理提供参考。

Current Situation Analysis of Water Consumption in Hotan River Basin

Hotan river basin is located in the arid zone, there are scare precipitation and strong evaporation, water consumption is the main form of water motion in the area. With the dissipative hydrological model for hotan oasis, the current situation of water consumption in the Hotan river basin was analyzed comprehensively. From the multi-aspects of river channels as reservoirs, groundwater and irrigation districts of oasis, the annual distribution of basin water consumption, the water-consumption proportion of social economy and natural ecosystem showed the water-consumption situation levels respectively, which can provide the reference for reaonable allocation and management of soil and water resources in Hotan river basin in the future.
