浦东新区土地利用的时空变化分析

根据2000年和2003年2期航空影像资料，运用遥感影像的机助解译方法、地理信息系统空间分析方法以及数理统计的方法，分析了浦东新区2000-2003年间土地利用的数量和空间变化特征.揭示了该区各类土地利用数量变化的幅度、速度和区域分异以及土地利用空间变化的主要类型和分布特征.阐述了该区土地利用变化的特点与驱动机制，为高强度人类活动下土地利用调控与管理提供借鉴和指导意义.

Spatial-Temporal Change of Land Use in Pudong New Area

Based on GIS and RS methods, the aero-photographs taken during 2000 and 2003 covering Pudong New Area were interpreted, then in both spatial and temporal aspects, the situation of land use change in the area were analyzed. The results showed that in Pudong New Area from 2000 to 2003, the cultivated land and water body area decreased by 4 313 hm^2 and 556 hm^2 , at the ratio of 6.6% and 3.6% per year, respectively. The build-up land expanded with an increase of 4 627 hm^2, mainly from cultivated land. There are significant difference between towns, land use changes faster in Gaodong, Jinqiao, Zhangjiang and Huamu towns which lie in the urban fringe of Shanghai, and slower in Jichang and Heqing towns that is far from main city zone of Shanghai. The driving forces of LUCC are mainly due to the urbanization, that is, the increase of traffic land use, the rapid development of industrial estate and the rapid growth of population.
