江西省土地利用变化特征及驱动力分析

Analysis on Land Use Change and Its Driving Forces in Jiangxi Province

土地利用变化及其驱动机制研究是土地利用转型研究的重点。以江西省所辖的9个地级市为研究区域,以土地利用遥感数据与江西省统计年鉴为数据来源,借助单一土地利用动态度和土地利用转移矩阵研究方法分析工业化、城市化进程中江西省土地利用变化态势及区域特征,得出土地利用变化的结构特征和各地类之间的转移方向,并从人口变化、经济发展、居民生活、政策四个方面进行主要驱动力分析,以期为江西省土地可持续利用提供理论依据。

Land use change and its driving mechanism are the focus of research on land use transition. In this paper, we take 9 prefecture-level cities in Jiangxi Province as the study area, with using land use remote sensing data and Jiangxi Statistical Yearbook as the data sources, to analyze the dynamic change and regional characteristics of land use change in Jiangxi Province in the process of industrialization and urbanization,, with using the methods of singularity dynamic change of land use and the transfer matrix. We then fnd the structural change of direction of land use and the transfer between different land types were analyzed. The main driving forces were analyzed from the aspects of population change, economic development, residents＇ life and policy, with aim to provide the theoretical basis for the sustainable land use.
