The compound water resource system was regarded as the subjectinvestigated. The coupling relationship between water resource utilization and eco-environmentwas 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 setup according to metric demands of sustainable water resource utilization. The principles of erecting evaluation system were established. Indexes were filtrated by frequency analysis method,theoretical analysis method,and expertconsultation method. Weightof each indicator was determined by expertconsultation method and Improved Analysis Hierarchy Process (IAHP) and thus,the subjective deviation was reduced. The weighted values of indicators were finally analyzed. Results indicate thatthe essential attributes of water resources are the most important aspectof judging the sustainable utilization degree of water resources,whereas the influence of fragile eco-environ-mentranks second.
