摘要
以1996-2008年高淳县土地变更数据为资料,分析了12年中土地变化的特点及主要驱动力因子。结果表明：12年来全县土地利用类型的变化主要表现为耕地的大幅度下降和建设用地的增加;影响该县土地利用变化的主要驱动力因子是经济增长和城镇化水平的提高;全县GDP每增长1亿元,需新增建设用地23.29 hm2、减少耕地45.32 hm2;城镇化率每提高1个百分点,需减少耕地173.13 hm2。
Base on the data from land use change survey in Gaochun Country from 1996 to 2008,this paper focuses on the research of land use change and its driving forces in Gaochun from 1996 to 2008.Results suggest that the tendency of land use change is that the amount of cultivated land is decreasing largely and most construction land is increasing rapidly.The economy increase and improvement of urbanization level influence the whole land use change.Once the GDP of the entire city increases 100 million,23.29 hm2 of newly increased construction land are needed and 45.32 hm2 of arable land are lessened.Meanwhile,with the increase of 1% urbanization,173.13 hm2 arable lands have been lessened.
