An ecological network can improve regional landscape connectivity,increase the exchange of material,energy,and genetic material between patches,and play a significant role in promoting biodiversity conservation.In previous research,empirical or graph theory approaches have been explored as approaches to landscape model construction,but little research has been conducted on constructing ecological networks built up on species-environment correlation models with long-term observation data for specific species.In this study,based on 15 years of long-term observations of birds and urban and rural environmental data(2007-2021),we investigate the influence of urban and rural environmental characteristics on bird diversity,identify the spatial distribution of important bird habitats,and establish a protection system for ecological sources,ecological corridors,and ecological networks utilizing birds as indicators.Furthermore,we analyze the risk of ecological network encroachment based on the urban expansion model,classify the importance and sensitivity,and identify the difficult and painful points of bird diversity conservation.This study is expected to provide empirical support for the development of ecological networks in the Wuhan Metropolitan Area for the conservation of avian diversity as well as theoretical references for the identification of important ecological spaces and ecological restoration in territorial spatial planning for biodiversity conservation.
