摘要
利用1985年、1995年、2005年、2008年4期遥感解译获取的土地利用数据,基于"三生"(生产用地、生活用地、生态用地)土地利用主导功能分类体系,借助ArcGIS和社会学网路分析软件(Ucinet),采用土地利用转移矩阵、重心转移模型等研究方法,定量研究苏南地区1985~2008年的土地利用格局变化过程、特征及规律。研究结果显示:1985年以来苏南土地利用变化主要表现为生产用地的大量减少、生态用地的略有增加和生活用地的显著增加;其中,农业生产用地、水域生态用地、城镇生活用地、农村生活用地四种地类空间转化明显;农业生产用地为主要转出者,城镇生活用地、农村生活用地为最主要的转入者。
The purpose of this paper is to reveal the process,characteristics and distribution of land-use pattern change in Southern Jiangsu(SJ)from 1985 to 2008.According to land use classification based on leading function of production,ecology and living,we employed the land use raster data of the year 1985,1995,2005 and 2008by remote sensing interpretation obtained from Landsat TM and ETM +.The methods included land use matrix,gravity center model,and Sociological network analysis software.The results indicate that SJ has gone through a severe land use change period that land use change that Since1985 when productive land decrease significantly while ecological land increase slightly and living space increase significantly.Agriculture land,water ecological land,urban living space,rural living land spatial distribution changed significantly.This paper concludes that agricultural productive land has been the main source of other lands,while living land which has become the main recipients.
