Abstract:

This paper, aiming to classify the engineering types in land development and consolidation in Jiangxi province, uses overlapping analysis and clustering analysis to classify Jiangxi ^,s engineering types based on county basic unit and expert decision system. According to engineering type classification method for provincial land development and consolidation, Jiangxi^,s 99 counties(cities, districts) are classified as 3 class I type regions, Poyang lake low hills region, central Jiangxi hillsbasins region, and Jiangxisurrounding mountains region, and 6 class II type regions(engineering mode), lake-plain mode, river-plain mode, low hills mode, valley basin mode, sandstone hills mode and low hill to mountain mode. And a map is completed with their distribution. This classification has been proven feasible, providing technical support to Jiangxi^,s land development and consolidation.

摘要：

研究目的：对省级土地开发整理工程类型区划分影响因素、划分方法和程序进行探讨，并对江西省进行实证研究。研究方法：采用叠加分析法和聚类分析法相结合，以县域为基本划分单元，按评价指标体系进行聚类分析，并结合专家决策系统形成最终分区成果。研究结果：按照省级土地开发整理工程类型区划分方法，将江西省99个县（市、区）划分为3种一级类型区：鄱阳湖平原岗丘类型区、赣中丘陵盆地类型区、赣周边丘陵山地类型区和6种二级类型区（工程模式）：环湖圩田平原工程模式、河网平原工程模式、岗地低丘工程模式、河谷盆地工程模式、红砂岩类丘陵工程模式和丘陵低山工程模式，形成了类型区分布图。研究结论：本研究确定的分区方法科学合理，易于操作，江西省土地开发整理工程类型区成果符合江西实际，对江西土地开发整理工作提供了有力的技术支撑。
