新疆农业水土资源时空匹配研究

水土资源是农业可持续发展的核心,水资源的合理利用会影响到土地的利用方式。为了分析新疆农业水土资源匹配状况,本文采用农业水土资源匹配系数对2008-2017年新疆14个地、州、市的水土资源时空匹配程度进行研究。研究结果表明:从时间上看,2008年到2017年,新疆农业水土资源匹配系数呈现出增加的趋势。从空间分布上看,北疆地区的农业水土资源匹配系数整体较低,南疆地区的农业水土资源匹配系数较高。通过对2008年和2017年新疆农业水土资源匹配系数的差值对比发现,克孜勒苏柯尔克孜自治州、阿勒泰地区、伊犁哈萨克自治州(直属)、乌鲁木齐市和和田地区的农业水土资源匹配系数的变化较明显;博尔塔拉蒙古自治州和喀什地区农业水土资源匹配系数降低最明显。

Research on Time and Space Matching of Agricultural Water and Soil Resources in Xinjiang

Water and soil resources are the core of sustainable agricultural development.The rational use of water resources affects the way of land use.In order to analyze the matching situation of agricultural water and soil resources in Xinjiang,this study uses the matching coefficient method to reveal the spatio-temporal variation of water and soil resources coupling in 14 cities,states and cities of Xinjiang from 2008 to 2017.The results indicated that the matching coefficient of agricultural water and soil resources in Xinjiang increased from 2008 to 2017.The amount of water resources per unit area in northern Xinjiang is greater than that in southern and eastern Xinjiang.The matching coefficients of agricultural soil and water resources in Kizilsu Kirghiz Autonomous Prefecture,Altay region,Ili Kazakh Autonomous region,Urumqi City and Hetian region are increased significantly,while that in Bortala Autonomous Prefectureand Kashgar decreased significantly from 2008 to 2017.
