摘要
番禺区作为广州市新的发展方向,处于中国经济和社会发展的前沿。研究番禺区20年来的景观格局变化,对于其经济社会的可持续、健康发展有一定的指导意义。利用番禺区1979年、1990年、2000年的MSS、TM、ETM+影像,在GIS的支持下,结合景观生态学的理论分析了番禺区三个时期的景观格局及其动态变化。结果表明,20年来,番禺区的景观格局变化迅速,斑块数量和空间格局变化较大;各景观类型之间的转移明显,耕地、林地快速向建设用地、养殖水域等转变。人文因素是景观格局变化的直接驱动力,人口增长、经济发展是导致景观系列变化最根本的原因。
Panyu District, the Guangzhou recent development area, is in the front of Chinese economy development. Studying the landscape pattern change of Panyu District for 20 years, it has a certain instruction significance to the Panyu＇s economic sustainable and health development. Using Panyu＇s 1979,1990,2000 MSS, TM, and ETM^＋ images, under the support of GIS and landscape ecology theory, this study analysises landscape patterns and its dynamic change of Panyu District. The result indicated that, for 20 years, landscape pattern change of Panyu District is rapid ; Quantity and spatial pattern change are bigger; The shift between various landscape types is obvious ; The shift to the water or the construction land from the cultivated land, the forest land is very quick. The humanities factors are direct driving forces of the landscape pattern change, the population growth, the economical development are the most basic reasons to the change of the landscape.
