汉江流域水资源现状及承载力研究

Study on Carrying Capacity Water Resources and Status of Hanjiang River Basin

汉江流域特别是中下游分布着较为发达的农业区或产业区,其自身经济总量在长江流域举足轻重,若干产品在全国占有突出地位,尤其是粮食生产在全国粮食生产战略中具有重要地位。伴随着汉江经济社会发展快速增长,尤其是本世纪以来,对汉江水资源的需求也日益增长,水生态环境压力日益加大,流域水安全面临较大挑战,本研究依据汉江流域的水资源现状,通过指标分析法展开对汉江流域承载力的研究,为合理开发利用汉江流域的水资源提供借鉴意义。

Distribution of the middle and lower reaches of Han Jiang river basin,especially in the more developed agricultural or industrial district,whose economy plays an important role in the Yangtze River basin,and a number of products in the country has a prominent position,especially grain production which has the important status in the national grain production strategy. Accompanied by the Han river rapid growth of economic and social development,especially since this century,Han river water demand is growing, with ecological environment water pressure increasing and watershed water security facing bigger challenges. This study based on the Han river basin water resources present situation, through the analysis on the bearing capacity of the Han river watershed research,to provide reference for reasonable exploitation and utilization of the Han river basin water resources.
