摘　　要：以武汉市为例,利用情景分析法,结合基于最小加权费用路径模型的Ecological Network模型识别生态网络,并利用网络连接度指数和斑块关联度指数对整体网络结构和生态源地斑块关联度进行了定量分析与评价。研究发现,武汉市森林生态网络空间分布不均,城市交通网络对生态网络的整体结构影响较大,网络结构、数量与生态源地斑块关联度指数均呈由城市中心向城市远郊区逐渐复杂与增加的趋势。在此基础上,提出了网络保护策略,为武汉市森林生态系统保护与城市空间发展提供了科学依据与参考。Taking Wuhan City for example,combining with Ecological Network model based on the minimum weighted cost path model,we used scenario analysis method to identify ecological networks.Then,we used network connection index and patch correlation index to analyze and evaluate the overall network structure and ecological source patch correlation quantitatively.We found that the spatial distribution of Wuhan’s forest ecological network was uneven,and the urban transportation network had a greater impact on the overall structure of ecological network.The network structure,quantity,and ecological source patch correlation index all showed a trend of gradual complexity and increase from the city center to the outer suburbs of the city.On the basis of this,we put forward some network protection strategies,which could provide scientific basis and reference for the forest ecological system protection and urban spatial development in Wuhan City.
