摘　　要：将水资源—生态环境—社会经济复合系统作为研究对象。探讨了水资源开发利用与生态环境之间的耦合关系,提出了水资源可持续利用是促进水资源开发与生态环境协调发展的有效措施。根据水资源可持续利用的量度需求,将水资源可持续利用指标体系分成3个层次,分别为目标层、准则层和指标层。确定了评价指标体系建立原则,采用频率统计法、理论分析法和专家咨询法设置、筛选指标,使指标的配置更加合理;采用专家咨询法和改进层次分析法相结合的方法确定指标权重,降低了主观性偏差,为后续评价奠定了基础。对各指标权重值进行综合分析发现,水资源本身的属性是衡量岩溶水资源可持续利用程度的最重要方面,脆弱的生态环境对水资源可持续利用程度具有重要的影响。The compound water resource system was regarded as the subject investigated. The coupling relationship between water resource utilization and eco-environment was ascertained. Sustainable water resource utilization was found to be the effective measure of harmonizing water resources and eco-environment, An evaluation system including the three levels of target, rule, and index was set up according to metric demands of sustainable water resource utilization. The principles of erecting evaluation system were established. Indexes were filtrated b od. Weight of each y in frequency analysis method, theoretical analysis method, and expert consultation methdicator was determined by expert consultation method and Improved Analysis Hierarchy Process （IAHP） and thus, the subjective deviation was reduced. The weighted values of indicators were finally analyzed. Results indicate that the essential attributes of water resources are the most important aspect of judging the sustainable utilization degree of water resources, whereas the influence of fragile eco-environment ranks second.
