基于景观指数聚类的粤北典型区景观生态区划
Landscape ecological cluster analysis of typical area in north Guangdong
摘要
Abstract
landscape ecological regionalization play an important role in landscape ecological planning, but the apply of landscape index is still rare to see in landscape ecological regionalization. By selected different levels of landscape index, this paper make a zoning for Landscape Ecological sub-areas in typical area of Northern Guangdong, which aimed to discuss the apply of landscape index in landscape ecological regionalization and provide a new concept and method for Landscape Ecological Regionalization. this paper take 2009 Digital Orthophoto map (DOM) of Nanxiong, Guangdong Province as a data source. First of all, RS images were interpreted and classified through ENVI 4.3 and ARCGIS 9.3, then the landscape type are divided into 6 classes include: Farmland,Woodland, open woodland, urban construction land, water, unused land; secondly, the study area are divided into 18 sub-areas by Township administrative boundaries; thirdly, different of levels landscape indexes are calculated by Fragstats 3.3; Finally, uses choose landscape index as variable factors, 18 landscape ecology sub-areas as clustering object, select the SPSS 17.0 Q Cluster Analysis method calculate the landscape indexes of study area. After these works, The area divided into 4 partitions by select the horizontal distance of 7.5 as the standard line. The result shows that the landscape structures are highly consistent in each partition.Through the research above all, the author argued that the apply of landscape metrics in landscape ecological regionalization is better reflect the prominent landscape features and spatial variation conditions of landscape ecological structure through clustering analysis,it provided a new zoning method and ideas for landscape ecology regionalization关键词
