摘　　要：针对传统的生态廊道构建方法难以适用于土地利用复杂且生境质量较差的城市环境的问题,该文提出了利用电路理论,将生物多样性保护能力和城市生态廊道的建设成本与效益相结合,建立城市综合阻力面的方法,并对城市地区的生态廊道构建方案进行了模拟。该文利用提出的方法识别出武汉市20个生态源地和44条生态廊道,分析了生态网络中的生态夹点与生态障碍点,区分了廊道建设的优先级,最终形成兼顾自然环境和人类活动与的城市生态廊道构建方案,可为城市生态廊道建设提供科学指导。Aiming at the problem that the traditional ecological corridor construction method was difficult to apply to the urban environment with complex land use and poor habitat quality,this paper put forward a method to establish urban comprehensive resistance surface by combining the capacity of biodiversity conservation with the construction cost and benefit of urban ecological corridor by using circuit theory,and simulated the construction scheme of ecological corridor in urban areas.The paper finally identified 20 ecological sources and 44 ecological corridors in Wuhan,analyzed the ecological pinch points and ecological obstacles in the ecological network,distinguished the priority of corridor construction,and finally formed the urban ecological corridor construction plan that takes into account the natural environment and human activities,which could provide scientific guidance for the urban ecological corridor construction.
