以汉江中游襄阳市为研究对象,在分析襄阳市自然地理和社会经济条件的基础上,构建反映区域水资源承载力水平的评价指标体系,由17项指标组成,利用向量模法对襄阳市2000—2012年的水资源承载力进行现实评价。结果显示,期间襄阳市水资源承载力评价值维持在0.2939~0.4114,属于较弱承载力,但有不断改善的趋势。随着2014年中线工程首次实现调水,汉江下泄水量减少,其水资源供需矛盾将更加突出。研究结果对于襄阳市科学合理地开发利用水资源、加强生态环境建设,以减小调水带来的不利影响,具有一定的理论参考价值和实践指导意义。
Based on the analysis of Xiangyang natural geography and socio-economic conditions, an evaluation index system reflecting the level of regional water resources carrying capacity is constructed in Xiangyang City in the middle reach of the Hanjiang River. It is composed of 17 indicators. By using vector modeling, - 2012 water resources carrying capacity of realistic assessment. The results showed that during the period, the evaluation value of water resources carrying capacity in Xiangyang remained at 0.2939 ~ 0.4114, which belonged to weaker bearing capacity, but there was a trend of continuous improvement. With the first transfer of water to the midline project in 2014, the amount of discharged water from the Han River will decrease, and the contradiction between supply and demand of water resources will become even more prominent. The results of the study have certain theoretical and practical significance for Xiangyang City to develop and utilize water resources scientifically and reasonably, and to strengthen the construction of ecological environment so as to reduce the adverse effects caused by water diversion.
