| 摘 要： | 目的]研究江苏省2002—2011年农业水资源利用效率,为提高该省农业水资源利用率提供依据。方法]采用数据包络分析(DEA)模型中C2 R和BC2两种模型,选取的投入指标为农作物播种面积、农田灌溉用水量、农田灌溉耗水量和农业在岗职工人数;产出指标为有效灌溉面积、农村居民人均农业收入、农业生产总值和农作物产量。结果](1)在2002—2011年期间,江苏省农业水资源利用效率处于较高的水平,DEA有效年份占50%;(2)造成DEA无效既有技术原因也有规模原因,存在投入冗余和产出不足;(3)随着时代发展,江苏省农业水资源利用投入冗余和产出不足整体呈现逐渐降低趋势。结论]江苏省农业水资源利用情况得到了逐步改善。

| Abstract: | Objective] The agricultural water utilization efficiency of Jiangsu Province from 2002 to 2011 was investigated in order to provide the basis for improving the utilization efficiency of agricultural water resources in the province. Methods] Both C2R and BC2 models of data envelopment analysis(DEA) were used. The input indicators included crop planting area, farmland irrigation volume, water consumption of farmland irrigation and the numbers of employed staff engaging in agriculture. The output indicators included effective irrigation area, agricultural per capita income of rural resident, gross agricultural production and crop yield. Results] (1) The agricultural water utilization efficiency of Jiangsu Province is at a higher level during the periods from 2002 to 2011, the effective years of DEA accounted for 50%. (2) Reasons were both technology and scale in the invalid years of DEA. The invalid years of DEA had shown the input redundancy and output deficiency. (3) With the development of times, the trend of input redundancy and output deficiency in agricultural water utilization is slowing down in Jiangsu Province. Conclusion] The utilization of agricultural water resources in Jiangsu Province had been improved. |
