四川省农用地集约利用评价及区域差异分析

用改进的熵值法、综合评价法、聚类分析法,对四川省21个市(州)2007年农用地集约利用度进行评价,分析其区域差异,为科学合理的利用农用地提供参考依据。结果表明:①四川省农用地集约利用度整体水平不高;②农用地集约利用水平区域差异明显,集约度最高的成都市是集约度最低的甘孜州的4.5倍。应用综合评价法进行农用地集约度评价以及采用聚类分析法进行区域分异分析,评价结果与现实情况基本相吻合,具有一定的可行性。

Agricultural Land Use Intensity Evaluation and Regional Disparity Analysis in Sichuan Province

With the method of analytical Hierar-chy process,improved ent ropy method,comprehensive evaluation and cluster analysis,this paper evaluated the intensity use of agriculture land in 21 cities of Sichuan province and analyzed the regional differences in order to provide a reference for scientific and rational use of agricultural land.The results showed that: ①the overall level of intensive agricultural land use in Sichuan province is not high;②significant regional differences exist in the level of intensive agricultural land use in Sichuan.The level of intensive agricultural land use in Chengdu,which is the highest,is 4.5 times as that in Ganzi autonomous prefecture,which is the lowest.This paper applied comprehensive evaluation method to evaluate agricultural land use intensity and cluster analysis to analyze regional differentiation,the evaluation results coincided with the basic realities,with a certain degree of feasibility.
