Abstract:

江苏省环太湖地区快速城市化和工业化加剧饮用水危机,整合研究水源地、供水、用水、排污处理和技术5个方面对于支撑该地区可持续发展的适应能力,对揭示饮用水供需关系、存在问题、部门协调与综合决策等具有现实意义.本文以构建5个子系统适应能力指标体系为主线,通过分指数与综合指数评价的运算,得出研究地区饮用水系统适应能力等级水平、地域分异特征及影响因素分析;针对各子系统存在问题,提出维护和提升适应能力的对策措施.研究表明,适应能力较强的地区占总面积29.1%,其5个子系统适应能力均较强.适应能力中等地区占41.2%,一类是各子系统适应能力基本均等,另一类是排污处理子系统适应能力较强,但用水子系统得分较低.适应能力较差地区占29.7%,主要是技术子系统分值低,其它子系统适应能力处于中等偏下.因此需加大对各子系统适应能力的调控与提升.
