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,借助GIS空间分析软件,利用ESDA等方法,对江西省各地貌区耕地集约利用水平空间差异及其驱动机制进行了研究,针对各地貌区制约耕地集约利用因素,分别提出了今后耕地利用过程中应注意的问题。结果表明:两时段基于综合度的Global Moran's I分别为0.16和0.30,在显著性水平α=0.05下呈空间正相关,耕地集约利用水平在地域上呈现出较明显的空间集聚特征与区域差异性,且有不断加强趋势。总体上平原区的集约水平高于丘陵与山区的,经济发展较快地区的相对较高;各研究实体Local Moran's I及Grid图,反映了...

Abstract:: Based on global and local spatial autocorrelation analyses of exploratory spatial data，the spatial disparity and driving forces of cultivated land intensive utilization at the county level were discussed by using ArcView GIS and Geoda software. The results show that：Global Moran's I value was 0.16 and 0.30. There was an obviously temporal increase of Moran's I value from timeⅠtoⅡ.The global spatial autocorrelation for intensive utilization levels of cultivated land was significant. The spatial clustering phenomenon about regional intensive utilization levels of cultivated land appeared on the whole. The intensive utilization levels was almost the same in some region by analyzing the Grid figure of Local Moran's I. The character of spatial clustering about regions of high value and low value was significant. The quantity of counties with the positive association was higher than that with the negative association. 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. The result of study conforms to the facts basically and has certain feasibilities. The main driving forces influencing cultivated land intensive use in different regions were different.
