摘　　要：为了分析关中地区农业水土资源的时空匹配情况,应用农业水土资源匹配系数,评价了关中地区及所辖5个地级市的农业水土资源匹配程度。结果表明:关中地区水资源短缺、人水矛盾和人地矛盾突出;农业水土资源匹配格局的时间变化不明显,而空间匹配存在明显的差异,宝鸡市和西安市的匹配程度优于其他市区,咸阳市的匹配程度最差。因此,应该通过跨流域调水工程、提高有效灌溉面积、改进农业结构等措施,提高关中地区农业水土资源的匹配程度。In order to analyze the spatial-temporal match pattern of agricultural water-land resources in Guanzhong area,agricultural water-land resources match coefficient was used to evaluate the match degree of agricultural water-land resources of Guanzhong area and the five prefecture-scale regions in this area.Results showed that water resources were short with significant human-water and human-land conflict.In addition,temporal variation of agricultural water-land resources match was not evident,spatial match,however,existed great variation.Baoji City and Xi＇an City had a higher match degree than other cities,and Xianyang City had the lowest match degree.Consequently,agricultural water-land resources match degree in Guanzhong area may be improved by introduction of inter-basin water transfer projects and increasing water-land utilization and strengthening water-land resources protection practices.
