Assessment of sustainable use of water resources based on combination of weighting method in Jimo
Taking Jimo for example ,the paper used DPSIR model to build the evaluation system for sus-tainable use of water resources and determined the index weight by combination of objective weighting method which combines the variation coefficient method and entropy method .The result showed that①the combination of variation coefficient method and entropy method can better reflect the relative importance of the evaluation index .The main factors impacting Jimo's water resources sustainable utilization level are natural population growth rate , afforestation area ,ratio of environmental protection investment account for GDP, percentage of ecological water ,GDP growth rate;②Jimo's sustainable utilization level of water re-sources presents the trend of “rising(1999-2005) -falling(2005-2009)-rising(2009-2011)”.At last, the paper proposed the response strategy from the three aspects of building multiple water supply system , forming water saving utilization way and improving the management and operation schedule of wa -ter resources.
