江苏省耕地保护区划研究

文章以江苏省58个县级行政区为区划单元,应用主成分析法得出影响耕地保护的4个主成分,在此基础上应用聚类分析法初步得出耕地保护区,再结合定性分析最后确定六大耕地保护区。从区划结果看,与江苏省综合农业区划相一致,与客观实际能很好地吻合,说明应用综合数值分析模型研究耕地保护区划是成功的。最后,对得出的六大耕地保护区进行了简要的分析,为有计划分区制定耕地保护政策、措施提供了理论基础。

STUDIES ON REGIONAL PLANNING FOR ARABLE LAND PROTECTION BY APPLYING COMPREHENSIVE NUMERICAL VALUE ANALYSIS METHOD IN JIANGSU PROVINCE

This paper takes 58 districts of county level in Jiangsu province as unit for regional planning, adopts major element analysis method and gains 4 main elements which will influence arable land protection. On this basis, it applies clustering analytical method and gains regions for arable land protection. Then combining qualitative analysis, 6 big arable land protection regions were confirmed at last. From the results of regional planning, it is identical with the comprehensive agriculture regional planning of Jiangsu Province and can inosculate with the subjective reality. This indicates that using comprehensive numerical value analysis model to study regional planning of arable land protection is successful. Before ending this paper conducts simple analysis on 6arable land protection regions, so as to provide theoretical basis for developing arable land protection policies and measures according to different regions and in a planned way.
