摘要
采用主成分分析提取影响水资源安全变化的主因子,利用熵值法确定简化后各新指标的权重,最后计算水资源安全综合评价指数。以六盘水市为例,分析了其8a的水资源安全的变化情况,探讨该区水资源安全的变化规律及其驱动因素,以便为六盘水市水资源的合理年际调配利用提供借鉴,以指导六盘水的可持续发展。
The paper extractes from main factor of water resources security changes on principal component analysis.It determines weight of each new index on entropy method and calculation comprehensive evaluation index of water resources safety.Take Liupanshui as an example,it is analyzed to water resources security changes about 8years.It discusses this region water resources security changes and driving factors of water resources,so that it to will provide reasonable annual deployment of utilization of reference and guide the sustainable development in Liupanshui City.
