摘要
以广东省佛山市顺德区为研究对象,在GIS平台下,根据1979、1990和2000年遥感影像解译获取的景观动态数据,分析了最近20多年顺德区景观格局动态变化规律。结果表明,顺德区城市化的迅速发展,使得该区的基塘地、耕地和林地大面积退化,而居民地面积大幅度升高。在此基础上,分析了顺德区景观格局变化的驱动因子,并提出了维持经济可持续发展所需要解决的若干问题及建议。
With the help of RS and GIS, the remote sensing images of 1979, 1990 and 2000 in Shunde District of Foshan are interpreted. The landscape diversity, the degree of evenness, the degree of fragmentation and cohesion index are calculated by use of theories and methods of landscape ecology, which reveals the dynamic regularity of landscape pattern of Shunde in recent 20-odd years. The results show that ： great changes of landscape took place in Shunde from 1979 to 2000, the areas of faxmland and woodland had a rapid decrease; the faxmland decreased from 227. 77 km^2 in 1979to 113. 16 km^2 in 2000, with a reduction of 114. 61 km^2 ; the woodland decreased from 46. 09 km^2 in 1979 to 15.40 km^2 in 2000, with a reduction of 30. 69 km^2. At the same time,the habitation-land increased rapidly by 149. 68 km^2. The dynamic characteristics of landscape pattern were caused by common action of natural environmental evolvement and long-term mankind activity. On this basis, some suggestions for the sustainable development of local economy are put forward.
