摘要:
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。
Abstract:
The paper established assessment indicator system with 17 indicators． The indicators could reflect the level of
regional water resources carrying capacity based on natural geography and social economic conditions of Xiangyang City，the
middle reaches of Hanjiang Ｒiver． Vector norm method was used to evaluate the water resources carrying capacity of Xiangyang
during 2000 to 2012． The results indicated that the water resources carrying capacity leval of Xiangyang was relatively low，
which varied from 0. 2939 to 0. 4114，but had a tendency of improvement． As the middle route of Chinese south-to-north water
transfer project achieved water diversion for the first time in 2014，the contradiction between supply and demand of water
resources would more prominent due to the reduction of discharged water． Ｒesearch results could provide theoretical reference
and practical guiding for Xiangyang to use water resources appropriately and enhance ecological environment construction，so
as to decrease the negative influence of water diversion and achieve sustainable development．
