珠海市土地利用变化规律及其驱动力分析

Analysis on the Characteristics of Land Use Change and Its Driving Force in Zhuhai City

利用1988～2008年的珠海市遥感图像,对珠海市土地利用类型进行提取和识别。结果显示,珠海市耕地、园地面积逐年减少,建成区、新开发区、水面及道路面积逐年增大;珠海市林地面积也有逐年增大的趋势,说明珠海市在经济发展过程中注重了林地的保护;土地利用综合指数在1998年达到最大值,2003、2008年略有下降,但均高于1988年;经济发展、城市规划、人口增长及产业调整是珠海市土地利用类型变化的主要驱动力。

The woodland area was also increasing,proving that the woodland was protected during the economic development of Zhuhai.
