摘要提高水资源利用效率和效益,是解决干旱和半干旱地区缺水问题的关键手段.运用数据包络分析法,从微观农户的角度出发,对张掖市甘州区农业水资源利用效率进行研究.基于对2012年甘州区农业灌溉用水和投入产出情况的调查数据,用DEAP2.1软件测度该地区农业水资源利用效率,并对农业节水潜力进行估算,最后针对分析结果提出提高农业水资源利用效率政策建议.结果表明:甘州区农业水资源利用效率水平高于农业生产效率水平;调整种植规模比减少水资源投入对提高农业水资源利用效率具有更明显的效果;农业水资源利用效率较高的几个乡镇水资源投入冗余较多,水资源浪费较严重,农业水资源利用效率较低的乡镇反而投入冗余较少浪费现象也较少.甘州区的农业节水潜力估算结果为7 682.5×104m3.研究结果对张掖市甘州区节水型社会建设试点的建设效果做出评价,为进一步提出如何提高农业水资源利用效率提供相关参考意见. Improving the water utilization efficiency is a key way to resolve water shortage in arid and semi-arid areas. In this paper,data envelopment analysis method is used to study the utiization efficiency of agricultural water resources in Ganzhou District,Zhangye Prefecture,Gansu Province,China,from farmers＇ view. DEAP2. 1 software is used to measure utilization efficiency of agricultural water resources and to estimate the potential of agricultural water-saving in this district based on thesurvey data of input and output in 2012 in the district.Finally,policy suggestions are put forward for howto improve the utilization efficiency of agricultural water resources based on this analysis. The results are shown as follows： firstly,the level of utilization efficiency of agricultural water is higher than that of the agricultural production efficiency in Ganzhou district. Secondly,the effect of adjusting the planting scale is more obvious than reducing water input to improve the utilization efficiency of agricultural water. Thirdly,the towns,whose utilization efficiency of agricultural water are higher,have more input redundancy of water,with serious water wasting; the towns,whose utilization efficiency of agricultural water is lower,have fewer water input redundancy with less water wasting. Fourthly,it is estimated that there is 76. 825 million cubic meters of agricultural water-saving potential in Ganzhou District.
