随着城市化进程不断加快,城市规模不断扩大,大量的城市建设不断蚕食生态绿地,造成城市生态用地破碎化,不连续的点状、片段的城市绿地生态功能下降,由此带来的城市热岛效应加剧、居民生态服务不均衡、生物多样性流失等生态问题日益突出。于是构建城市近自然生态网络体系,维护城市生态系统空间格局,成为城市健康发展的必然选择。生态网络构建的概念起源于19世纪末的公园规划时期,20世纪70年代后期城市生态网络逐 With the accelerating process of urbanization, expanding cities, a large number of urban construction continue to erode ecological green space, resulting in fragmentation of urban ecological land, discontinuous point-like, fragmented urban green space ecological function decline, resulting in urban heat island As a result, ecological problems such as unbalanced residents' ecological services and loss of biodiversity have become increasingly prominent. Therefore, building an urban near natural ecological network system and maintaining the spatial pattern of urban ecosystem have become the inevitable choice for the healthy development of cities. The concept of eco-network construction originated in the late 19th century park planning period, the 20th century, the late 70s of urban ecological network by
