摘　　要：分析水资源利用潜力,提高水资源利用效率对于解决城市水资源短缺问题十分重要。本文利用基于遗传算法的投影寻踪模型,选用万元GDP用水量、人均用水量、万元农业产值用水量、农田灌溉平均用水量、万元工业产值用水量为评价指标,对2009年陕西省11个行政区水资源利用效率进行评估。结果显示万元工业产值用水量对陕西省水资源利用效率影响最大,延安市的水资源综合利用效率最高。并针对最佳投影向量各指标权重提出了提高陕西省水资源利用效率的措施。Improving utilization efficiency of water resources is very important in solving water deficit issue in Shaanxi province.The method of projection pursuit based on genetic algorithm is used to estimate the water utilization efficiency of Shaanxi province in 2009.Some indicators for estimation of water efficiency are determined,which includes water consumption per unit GDP,per capita water consumption,agriculture water use of ten thousand yuan output,irrigation water consumption per mu,water consumption per ten thousand yuan of industrial output.On the basis of the database from 11 administrative districts in Shaanxi province of 2009,the results show that the impact of the amount of water consumption per ten thousand yuan of industrial output on water use efficiency is the largest one and the water use efficiency in Yan＇an city is the highest in Shaanxi province.Moreover,some measures for improving water use efficiency in Shaanxi are proposed based on the optimal projection vector.
