摘要:
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.

Abstract:
Based on a detailed discussion about the conception of urban drinking water system adaptation,the paper established an adaptive capacity assessment index system and model of drinking water system in areas around Lake Taihu from the aspects of adaptation factors in water sources,water supply system,water user system,sewage treatment system and social system.According to the model and the sub-index and integrated-index,the drinking water system adaptive capacity,including spatial differentiation, types and influencing factors of cities around Lake Taihu area in Jiangsu Province,was evaluated.The results showed that: regions with strong adaptivity accounted for 29.1% with all five sub-systems high value;regions with middle adaptivity accounted for 41.2% with two types-relatively equal and uneven;regions with poor adaptivity accounted for 29.7%,mainly due to the technical sub-system is in low values and other sub-systems are not high.Therefore it is necessary to increase the differentiation enhancement of the adaptive capacity of each sub-system.
Key words:  Adaptive capacity  urban drinking water system  rapid urbanization  areas around Lake Taihu
