1、⑨硕士学位论文MASTER’STHESIS摘要水是生命的源泉,是基础性的自然资源,是一切动植物赖以生存繁衍和发展的必须物质基础【ll;水资源也是战略性的社会经济资源,是一个国家的国民经济命脉,对维护区域生态环境和促进经济可持续发展具有重要意义。武汉城市圈当前处于城市化的快速发展阶段,国民经济各生产部门和居民生活用水量呈逐年上升趋势,水资源供需紧张、水污染严重等问题日益突出。武汉城市圈社会经济能否保持又好又快的发展势头,水资源的开发利用状况将起到关键的作用。因此,对武汉城市圈水资源承载力的现状进行综合评价有着积
2、极而重要的现实意义。本研究借助可持续发展的思想,利用复合系统协同学观点,建立以社会、经济、生态与水资源为4个子系统的区域水资源承载力复合系统,综合频度统计与理论分析方法选取了社会、经济、生态与水资源复合系统评价指标,构建综合评价指标体系,建立武汉城市圈水资源承载力综合评价模型,以武汉城市圈9个城市行政区2010年的基础数据为样本,计算武汉城市圈水资源承载力综合评价指数,并借助地理信息系统软件ArcGIS9.3进行图形空间分析,以此来展现武汉城市圈水资源承载力的承载状况和特点。研究表明:武汉城市圈水资源承载力综
