摘要
在广州"城市南拓"的背景下,以番禺区为研究对象,利用2005年土地利用现状图,在GIS的支持下,基于Fragstats软件平台,采用景观指标和梯度分析相结合的方法,对研究区的景观格局及其变化进行了定量分析。结果表明:运用梯度分析和景观指数相结合的方法来定量表现城市化与城市景观的空间格局的变化是可行的,在"城市南拓"的实施中,番禺区城市化水平不断提高,不同土地利用景观的空间格局及其变化特征差异明显。
Under the background of the ＂Southwardly Development＂ of Guangzhou City, with Panyu District as the research object, and used the 2005 land Use date. Under the support of GIS and fragstats, the landscape pattern and its change were analyzed quantificationally with landscape index and gradient analysis. The results showed that it was feasible to use the method which had been formed gradient analysis and landscape index to show urbanization and the change of the spatial pattern of urban landscape. Over the course of ＂Southwardly Development＂, the urbanization level in Panyu District enhanced unceasingly. And the spatial pattern and its variation characteristics were obviously different.
