| 摘 要： | 本文运用景观生态学原理 ,在不同空间尺度下 ,分析了半干旱岱海西岸地区景观空间异质性 ,认为该地区景观生态空间格局为明显的非随机格局 ;景观格局的异质性一般随尺度的加大而减小 ,景观要素间的差异在不同尺度水平表现不同 ;并且通过对景观要素出现频率直接加以比较 ,确定出不同样线之间差异性的大小。从宏观上为该地区的建设和经济发展提供了科学依据。

| Abstract: | This paper analyzes the landscape space hetergenerty of the plain on the western coast of Daihai lake in Liangcheng in different space scales according to the theories of landscape ecology,and concludes that the landscape space pattern in this area is obviously the non-random pattern.The hetergenerty of landscape pattern generally decrease along with the increase of scales;The differences among landscape elements show different in different space scales Comparing the occurance frequences of landscape elements,we can define the extents of differences among the line transects .So this study provides scientific bases for the construction and economic development in this area in macrostructure view. \ \ |
