基于遗传投影寻踪模型的延安市水资源利用效率分析

水资源是制约延安市社会经济发展的主要瓶颈,提高水资源利用效率对缓解该区域水资源短缺问题十分重要。本文选取万元工业产值用水量等7个指标,构建了水资源利用效率评价体系,建立遗传算法的投影寻踪模型,对用水效率进行分析评价。结果表明:延安市整体水资源利用效率较高,万元工业产值的用水水平为水资源利用效率的主要影响因素,并且根据最佳投影向量各指标提出了改善延安市水资源利用效率的措施。

Analysis of use efficiency of water resources based on model of genetic projection pursuit in Yan'an

Water resources is the main bottleneck restricting the social and economic development in Yan'an. Improving use efficiency of water resources is very important for alleviating water shortage problem in this region.This paper selected seven indicators such as water consumption per ten thousand Yuan industrial output to build water use efficiency evaluation system. At the same time, the efficiency of water resources was analyzed and evaluated by the projection pursuit model based on genetic algorithms.The result shows that the utilization efficiency of water resources is high in the whole region, and the water consumption per ten thousand Yuan industrial output is the main influence factor of utilization efficiency of water resources. According to the optimal projection vector,it put forward the improvement measures of enhancing the utilization efficiency of water resources in Yan'an.
