江西省县域耕地集约利用水平时空差异研究
Study on Spatio-temporal Difference in Intensive Use of Cultivated Land at the County Scale in Jiangxi Province
摘要
Abstract
This paper established an evaluation index system based on PSR model for intensive utilization of cultivated land,and determined the evaluation methods.On the platform of GIS and ESDA,the research for evaluation on intensive use of cultivated land was carried out on the county scale in Jiangxi Province.The intensive utilization level of cultivated land was divided into five grades and four types by using ArcView GIS and Geoda software.Based on global and local spatial autocorrelation analyses of exploratory spatial data,the spatio-temporal characteristics of intensive use of cultivated land were discussed.Results showed that the intensive utilization levels of cultivated land showed a general uptrend in recent 10 years in Jiangxi Province;the spatial clustering phenomenon for intensive utilization levels of cultivated land appeared on the whole;the regions with the ＇high—high＇ correlation were mainly located in the north of Jiangxi Province.However,the regions with the ＇low—low＇ correlation were distributed in hilly area of northeast,northwest and south.关键词
