摘要:
在构建衡量耕地集约利用水平的P—S—R模式指标体系基础上，以县域为基本空间单元，将GIS技术与空间相关分析等方法相结合，测度了江西省耕地集约利用水平状况，划分为5个利用水平等级与4种分异类型，并从时空角度探讨集约利用水平变化及其空间分异性。结果表明：近年来江西耕地集约利用总水平与单项水平不断提高，状态准则为影响主导因素；集约利用水平呈现出较明显的空间集聚特征与区域差异性，平原区集约水平高于丘陵与山区，经济发展较快地区水平相对较高；局域空间上，水平高、低区域各自集聚；LISA集聚类型中，以“H—H”、“L—L”类型为主，分别对应于高、低水平等级。其中，“H—H”关联的县域主要分布在北部平原区、经济实力较强的县（市），而赣东北、西北及南部的丘陵山区则表现出较为明显的“L-L”关联特征。
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.
