摘 要:为了维持西北旱区水土资源开发平衡,提高农业水土资源利用效率和效益,改善生态环境,针对农业水土资源匹配的研究现状,重新探讨了水土资源匹配的概念,提出了水土资源匹配指数计算方法,并在分析西北旱区2010年水土资源现状的前提下,计算了西北旱区各地级市及全省(自治区)水土资源匹配情况。结果表明,整个西北旱区农业水土资源匹配指数由西北干旱气候核心区向东南方向呈逐渐减小趋势,即灌溉农业区的水土资源匹配指数比雨养农业区偏大。西北旱区各地级市水土资源匹配指数以新疆吐鲁番最大,为3.08,甘肃庆阳最小,为0.02;水土资源匹配指数以新疆自治区最大,为0.56,内蒙古自治区最小,为0.18。In order to improve the efficiency of agricultural water and soil resources use and benefit, meet the need of agricultural sustainable development balance ,and improve the ecological environment, an innovative concept of soil and water resources matching index was redefined and re-explored on the basis of the current status of agricultural soil and water resources utilization, which was used to elucidate and quantify the situation of soil and water resources matching with 2010 as the baseline year in Northwest arid area. Results showed that soil and water resources matching index was gradually decreasing from arid core of northwest to southeast direction in northwest arid area, meaning that soil and water resources matching index of agricultural irrigation district was larger than that in rainfed agricultural region. The maximal soil and water resources matching index was 3.08 in Turpan of Xinjiang, the minimum soil and water resources matching index was 0.02 in Qingyang of Gansu;In addition, the maximal soil and water resources matehing index was 0.56 in of Xinjiang, and the minimum was 0.18 of Inner Mongolia.
