| 摘 要： | 基于覆盖番禺区域4个时相的TM遥感影像,综合运用遥感与G IS技术手段,结合FRAGSTATS景观格局分析软件,从数量结构、空间信息及位置转移和景观指数等方面,分析了番禺区土地覆被与景观格局的动态特征。数量结构分析结果显示,城市化过程中番禺区的耕地、园地、林地等自然资源利用程度在加大,自2000年起,这种变化的趋势开始减缓;番禺区土地覆被各类型之间频繁地发生数量与空间位置的变化,空间位置转换面积大于其数量变化面积,而且集中发生在邻近广州市中心城区的西北地区及南沙区;景观指数分析表明,番禺区土地覆被向破碎化方向发展,景观格局动态变化迅速。

| Abstract: | Based on the four TM images respectively in 1990, 1995, 2000 and 2005 years, and comprehensive used remote sensing and GIS technology, combined with FRAGSTATS landscape pattern analysis software, analyzed dynamic characteristics of the land cover and landscape pattern in panyu district, from the number of struc- ture, space and information transfer and landscape indices. It showed that the degree of the use of natural re- sources were increased during the panyu district urbanization process, such as the cultivated land, garden, wood land being transferred into construction and road lands. The period from 1990 to 2000 was one that the area of cultivated land, garden, wood land decreased most quickly. However, the tendency weakened since 2000. Be- sides, the transformation between different types of land cover changed very frequently, and spatial location of the conversion was larger than the number of changes in the area, also concentrated in nansha area and northwest corner of panyu district, that near the center of Guangzhou city. Characteristic indices of landscape revealed that the basic trends of land cover in panyu district included fragmentation and landscape pattern changed rapidly. |
