江西省土地利用变化及其驱动力定量研究

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

土地利用变化的驱动机制研究是探讨土地利用与土地覆盖变化研究的重点。以中部地区的江西省为例,利用土地利用变更数据与社会经济统计资料,通过分析土地结构变化、土地利用地域分布的特点,分析其工业化、城市化进程中的土地利用变化态势及土地利用变化驱动因素。通过主成分分析,得出江西省从1996年到2004年间,土地利用变化的主要驱动因素为人口、经济发展和农业科技进步。同时提出相应的土地管理对策,为区域土地可持续利用提供科学依据。

Driving force of land use is becoming the international research frontier. Taking Jiangxi Province as an example, in this paper, the change and driving forces in the process of industrialization and urbanization are analyzed by using the land use data and social - economic statistical data. According to principle component analysis, the three driving forces affecting the changes in land use are population increase, economic development and progress of science and technology in agriculture. Furthermore, the corresponding countermeasures are put forward for sustainable land use.
