Abstract
Land use/cover changes (LUCC) have been of great concern in global change research in recent years. Based on TM image data and other survey materials, this paper analyzed the spatiotemporal patterns of land use change along Coastal areas of the Pearl River Estuary in China during 1990-2005. The findings of this study were summarized as follows: Land use pattern changed dramatically during 1990-2005.Areas of built-up land increased by 2256.38km2 at an annual rate of 9.53%, increasing from 7.73% to 36.82% of the total amount. Arable land and woodland decreased by 1457.73km2 and 475.56 km2 respectively, mainly due to the expansion of industrial construction. Garden land and wetland showed only minor negative changes. Change of water was relatively stable and there was a little descending tendency. Relatively change ratio index (RCRI) was used to describe land use dynamic change situation of different region. During 1990-1995, Shenzhen had the largest RCRI (1.487), followed by Dongguan (1.458), the third was Zhuhai (1.227). Trends of RCRI change between 1995 and 2000 were quite similar with 1990-1995. It turned out to be land use changed more intensely in these three regions than that in Panyu and Zhongshan during 1990-2000. But during 2000-2005, Zhongshan and Panyu occupied the first and second place of RCRI, with the value of 1.309 and 1.098 respectively, showing that these regions have been become the investment hotspots after Shenzhen, Dongguan and Zhuhai.
