摘要
基于人水关系视角,从水资源负载能力和水资源承载力评价两方面对2005—2018年长江中游城市群水资源安全格局进行定量评价。结果表明,长江中游城市群负载指数大于1.5的城市主要集中在湖北省,江西省和湖南省只有少量分布。各省的城市水资源负载指数变化情况与长江中游城市群的变化趋势相似,2014—2017年负载指数变化幅度相对较大。2005—2018年长江中游城市群水资源承载指数由平衡状态逐渐变为盈余状态。
Based on the perspective of human-water relationship,the quantitative evaluation of the water resources security pattern of the urban agglomeration in the middle reaches of the Yangtze River from^(2)005 to 2018 was carried out from the two aspects of water resources carrying capacity and water resources carrying capacity.The results showed that the cities with load index greater than 1.5 in the middle reaches of the Yangtze River were mainly located in Hubei Province,and only a few were distributed in Jiangxi Province and Hunan Province.The change trend of the urban water resource load index of each province was similar to that of the urban agglomeration in the middle reaches of the Yangtze River,and the change range of the load index from^(2)014 to 2017 was relatively large.From^(2)005 to 2018,the water resource carrying index of the urban agglomeration in the middle reaches of the Yangtze River gradually changed from the balance state to the surplus state.
