客观评价灌区农业水土资源匹配现状是灌区可持续发展的前提。以江苏典型大型灌区为研究对象,通过计算水土资源匹配系数分析典型灌区水土资源匹配现状,计算耕地生产力和农田灌溉水生产力分析典型大型灌区水土资源生产力水平,并通过计算水土资源匹配系数和生产力的基尼系数,分析灌区水土资源空间匹配格局。结果表明,灌区水土资源匹配系数差异显著,其中高邮、沿运、涟西以及周桥灌区的水土资源匹配程度很好,显著高于江苏省水土资源平均配置系数。各典型大型灌区水土资源生产力水平虽差异显著,但总体高于江苏省水土资源平均生产力。灌区水土资源匹配的基尼系数为0.22,作为一个整体水土资源是均衡的,优于同期全国和全球范围内的水土资源匹配格局,耕地生产力和农田灌溉水生产力的基尼系数都为0.46,各大型灌区水土资源生产力空间分布有一定差异。

Objective evaluation of agricultural water and soil resources matching is the premise of sustainable development in irrigated areas. Taking typical large irrigation area in Jiangsu province as the research object, through calculating coefficient of water and soil resources matching analysis of current typical irrigation water and soil resources matching, cultivated land productivity and large scale irrigation farmland irrigation water productivity are calculated, typical water and soil resource productivity level is analyzed, the water and soil resources matching coefficient and productivity Gini coefficient are calculated to analyze irrigation area water and soil resources space matching pattern. The results show that the matching coefficient of water and soil resources in each irrigation area is significantly different. The matching degree of water and soil resources in Gaoyou irrigation area, Yanyun irrigation area, Lianxi irrigation area and Zhouqiao irrigation area is very good, which is significantly higher than the average allocation of water and soil resources of Jiangsu. Although there are significant differences among typical large-scale irrigation areas, the productivity of soil and water resources is higher than the average productivity of Jiangsu Province. The Gini coefficient of water and soil resources matching in irrigated areas is 0.22, which is balanced as a whole and better than the matching pattern of water and soil resources in the whole country and the whole world at the same time. The Gini coefficient of farmland productivity and farmland irrigation water productivity are both 0.46. The spatial distribution of water and soil resources productivity in various large irrigated areas is different.
