基于网络分析法的武汉市景观生态网络格局特征分析

从网络分析法的角度对武汉市水系网络、道路网络、绿地网络及其复合网络构成的景观生态网络格局进行分析。根据总体景观生态网络格局特征、分区统计景观生态网络格局特征、分等级统计景观生态网络格局特征分析结果显示,道路网络和绿地网络的α指数、β指数、γ指数都明显好于水系网络,相比较而言,三网复合网络都有比独立网络更好的连接度,分区统计结果显示,主城区复合网络的三项指标均处于最高,网络连通度最好,分等级统计结果显示,等级道路网络的α指数、β指数、γ指数均高于全部道路网络,等级水系和等级绿地网络的α指数、β指数、γ指数均低于全部水系和全部绿地网络。

The Characteristics of Wuhan City Landscape Ecology Network Pattern Based on Network Analysis

According to the network analysis method , the article analyzes the landscape ecological network pattern of Wuhan city , in-cluding the hydrographic network , road network , green space network and their complex network .Results show that , from different as-pects including the overall , administrative region statistics , hierarchical statistics of the landscape ecological pattern of network charac -teristics, the road network and green space network have significantly better index of α,β,γthan the hydrographic network;in com-parison, the three network composite has better connectivity degree than the independent network ; administrative region of statistical results show that , three indexes of complex networks of the main urban area are in the highest , and the network connectivity is best;hierarchical statistics show that , the index of α,β,γof hierarchical level of road network are higher than those of all the road net -work, the index of α,β,γof hierarchical level of hydrographic network and green space network are lower than those of all the hy -drographic network and green space network .
