干旱区绿洲全要素农业水资源利用效率时空分异研究——以新疆为例

     

摘要

By selecting the panel data of 14 cities in Xinjiang from 2004 to 2014 and using the input-oriented super-efficiency DEA model, the municipal and regional agricultural water utilization efficiencies are calculated, and the spatial-temporal differentiation is analyzed based on the meta frontier method and the total factor water efficiency measure. The results show that the agricultural water utilization efficiency in Xinjiang has an increasing tendency, and the agricultural water utility efficiency in three regions exhibits a subsequent decreasing trend in the northern, eastern and southern regions. The water consumption of agricultural water in the main areas of southern region, Urumqi City and Altay is in an inefficient state, that in Ili prefecture and Bortala Mongol Autonomous Prefecture is in a low-efficient state, and that in Karamay, Changji Hui Autonomous prefecture, Tacheng, Bayangol Mongol Autonomous Prefecture, Hotan and Turpan is in a high-efficiency state.%选取2004—2014年新疆14个地州市际面板数据,基于投入导向的超效率DEA模型,依托共同前沿理论方法,采用全要素水资源效率测度思路,对新疆地州市以及分区域农业水资源利用效率进行测度,并对其开展时空分异研究.研究结果表明,新疆地州市农业水资源利用效率呈现不断增长趋势,三大区域农业水资源利用效率呈现出北疆、东疆及南疆依次递减规律;南疆主要地区、乌鲁木齐市与阿勒泰地区农业用水处于无效率状态,伊犁州直属县(市)、博尔塔拉自治州农业用水处于低效率状态,克拉玛依市、昌吉回族自治州、塔城地区、巴音郭勒自治州、和田地区、吐鲁番地区等农业用水处于高效率状态.
