长三角地区1985～2015年土地利用变化及其驱动力分析

Analysis on Land Use Change and Its Driving Force in the Yangtze River Delta Region during 1985-2015

文章利用土地利用动态度、土地利用程度以及主成分分析法探讨了长三角地区近30年土地利用变化特征及其驱动力。结果表明:研究时段内长三角地区耕地面积减幅最大,而城镇用地面积增幅最大;随着城市化发展,土地利用程度不断提高;长三角地区土地利用变化的主要驱动力为经济发展、人口增加、城市化水平提高以及产业结构升级,这些因子共同对研究区土地利用变化产生了重要的影响。

This article discussed the characteristics and driving forces of land use change in the Yangtze River Delta Region for nearly 30 years with land use dynamic degree, land use level and principal component analysis. The results showed that the cultivated area in the Yangtze River Delta decreased significantly and the urban land area increased significantly during 1985-2015. With the development of urbanization, the land use degree has been continuously improved. The main driving forces of land use change were economic development, population increase, urbanization level and industrial structure upgrading. These factors had a significant impact on land use change in the Yangtze River Delta Region.
