基于PSR模型的江西省耕地集约利用时空变化特征研究
A Study on the Temporal and Spatial Variation Characteristics of the Intensive Use of Cultivated Land in Jiangxi Province Based on PSR Model
摘要
Abstract
The intensive use level of cultivated land is related to national agricultural production efficien⁃cy,farmers'income and food security. From the perspective of human⁃land relationship,this study constructed an evaluation index system for intensive use of cultivated land based on PSR model.And using the comprehen⁃sive index method,cluster analysis and GIS spatial analysis,taking 11 cities as the evaluation units the tempo⁃ral and spatial variation characteristics of intensive use of cultivated land from 2003 to 2012 in Jiangxi Province were quantitalively analyzed.The results indicated that the intensive use level of cultivated land from 2003 to 2012 in Jiangxi Province was fluctuating upwards.There were obvious territorial differences in the intensive use level of cultivated land and assumed a four⁃grade distribution in Jiangxi Province,and the intensive use level was the highest in the center and the west,secondary in the north⁃east and the lowest in the north⁃west and the south.关键词
