武汉市绿地网络与景观格局的相关性分析

Abstract

为了分析武汉市绿地网络对景观格局的影响，本文采用10个景观指数组成的景观水平尺度指标体系，利用Fragstats软件计算和分析景观水平指数，对武汉市五个空间圈层(即环城路以内、一二三四环之间、四环之外五个圈层)进行分析，得到武汉市景观格局的空间差异；同时分析武汉市绿地与农用地、建设用地、水域区域和其他土地利用类型的相关性，然后从景观形状、破碎化程度景观类型的面积构成、聚集度等方面进行分析，阐述武汉市绿地网络对景观格局的影响。 To analyze the impact of green space network of landscape pattern in Wuhan city, this paper uses landscape level scale index system according to 10 index landscape composition; Fragstats software is used to calculate and analyze the landscape level index; the five circle layers of space in Wuhan city (that is, within ring roads, among first second third fourth rings and outside the fourth ring, a total of five circle layers) are analyzed, and the spatial difference of the landscape pattern in Wuhan city is got. At the same time, we analyze the correlation of green land and agricultural land, construction land, water area and other land use types in Wuhan city, then elaborate the influence of Wuhan city landscape pattern of green space network from the landscape shape, the degree of the fragmentation, the area of landscape types, the aggregation degree and so on.
