摘要:

针对经济社会高速发展背景下水资源可持续利用问题,从水资源自然属性和社会属性出发,探讨了水资源阈值概念与内涵,提出水资源阈值可以表述为基于自然属性的水资源规模阈值和基于社会属性的水资源配比阈值,区域水资源阈值应为二者的有机耦合。以太湖流域为例,分析计算了太湖流域的水资源阈值:太湖流域的水资源规模阈值为1788亿m3;根据流域经济发展现状及未来规划目标,在流域生态和环境系统用水控制目标以及水体纳污能力约束下,社会经济系统用水阈值为156.4亿m3,占流域水资源规模阈值的531%;生态用水配比占流域水资源规模阈值的469%,充分体现了以生态为主、人水和谐的可持续发展理念。与2030年社会经济发展目标相对应的社会经济系统内部配比阈值分别为:生活用水98%;一产用水266%;二产用水582%;三产用水54%,为流域水资源持续利用提供了可资借鉴的依据

Abstract:

Given the current concerns with water resources sustainable utilization under the background of socioeconomic rapid development,water resources threshold including its definition and meaning based on the natural and social characteristic of water resources is studied.According to the research,water resources threshold can be described with the coupling of water resources quantity threshold in natural system and its allocation ratio threshold in the socioeconomic system.Then given an example of Tai Lake Basin,the water resources threshold is calculated.The results show that the water resources quantity threshold of the Tai Lake is 1788×108 m3.According to the current economic development and its future plans in the target,the water resources threshold in the socioeconomic system is 1564×108 m3 under the restriction of natural ecology system water demand and water environmental capacity of the Tai Lake.The ratio of water resources threshold in the socioeconomic system is 531%, and the ratio in natural ecology system is 469%.It demonstrates that natural ecology system and the sustainable development idea of harmony between human and water are more focused in the Tai Lake.The ratio threshold of water resources allocation between different industries is domestic consumption 98%,primary industry 266%,secondary industry 582%,and tertiary industry 54% respectively,which provides profitable information for water resources sustainable development and utilization in the Tai Lake Basin
