【摘要】：[目的]根据耕地后备资源的分布特征研究其开发组合序列是有效开发利用耕地后备资源、补充耕地的重要前提。文章利用江西省耕地后备资源调查评价成果,以县为分级单元对全省耕地后备资源进行开发潜力分级,对江西省耕地后备资源开发组合序列进行研究,从而为江西省耕地后备资源的开发顺序提供参考。[方法]利用Arc GIS空间图形分析法、DPS数据处理系统两维图论聚类等方法确定开发潜力等级以及开发序列。[结果]江西省耕地后备资源开发潜力从高到底依次分为Ⅰ级潜力区、Ⅱ级潜力区、Ⅲ级潜力区和Ⅳ级潜力区,面积分别为2.726 672万hm~2、2.306 897万hm~2、2.873 594万hm~2、1.378 88万hm~2。[结论]根据两维图论聚类法分析结果得知,江西省各县地域相似程度较高可优先开发的组合有进贤县-南昌县-余干县-鄱阳县-彭泽县;袁州区-分宜县-上高县-渝水区-樟树市;进贤县-南昌县-余干县-鄱阳县-都昌县和樟树市-渝水区-上高县-高安市-奉新县-安义县-永修县等。
[Abstract]:[Objective] according to the distribution characteristics of arable land reserve resources to study the development sequence is the effective development and utilization of cultivated land resources, an important premise to supplement cultivated land. The evaluation result of survey of Jiangxi province land reserve resources to the county as a unit on the grading of arable land reserve resources for development potential classification of cultivated land resource in Jiangxi province the development of composite sequence, so as to provide reference. Methods using Arc GIS spatial graphical analysis for the development of reserve cultivated land resources in Jiangxi Province, the order of the DPS data processing system of two dimensional graph clustering and other methods to determine the development potential and development level in Jiangxi province. The sequence of arable land reserve resources development potential from high in the end were divided into grade I potential region II potential region, class III and IV potential area potential region, area was 2.726672 hm~2,2.306 8 million 970 thousand hm~2,2.873 5 million 940 thousand hm~2,1.378 880 thousand 000 hm~ 2.[Conclusion] according to the results of the two dimensional graph clustering method that the combination of Jiangxi province regional similarity degree is higher priority to the development of Jinxian County - Nanchang County - Yugan County - Poyang County - Pengze County; District of Yuanzhou Fenyi County - Shanggao County - Yushui district - Zhangshu City; Jinxian County - Nanchang County - Yugan - Poyang county county - Duchang county and Zhangshu City - Yushui district - Shanggao County - Gaoan city - Fengxin County - Yongxiu County Anyi county.
