摘要
城市中绿化系统的片断化分布,直接造成动植物种群面临着重大的灭绝风险,严重影响生物多样性,降低了生态服务功能,进而直接威胁到人类自身的生存和发展。垂直森林建筑为现阶段人类社会创建了一个既能满足城市居住活动需求又能为多物种提供一定自然生境面积的建筑样本。但孤立的建筑绿化斑块无法实现自我维持,并持续为城市生态贡献价值。生态学中的生境片断化与物种分布动态研究,能够掌握城市绿地生态系统中植物种群维持的必要条件。本文基于集合种群理论建立生态模型,通过计算,模拟设计垂直森林生态社区格局,以降低系统中物种局域灭绝的风险,扩大此类建筑在社区中的生态效益,以巩固生态系统服务功能。
The fragmented distribution of greening systems in cities increases animal and plant’s extinction risk,and severely affects biodiversity causing ecological service functions reduction.The vertical forest architecture has created a new typology for human society that can not only meet the needs of urban living activities,but also provide a certain natural habitat area for multiple species.However,isolated architectural green patches cannot achieve self-sustainment and contribute value to the urban ecology constantly.The study of habitat fragmentation and species dynamics distribution in ecology can grasp the conditions for the maintenance of plant populations in urban green space ecosystems.These will optimize the spatial planning of the vertical forest complex in the urban landscape ecosystem.In the scope of expanding the ecological benefits,and consolidating ecosystem service functions,this paper establishes an ecological model based on metapopulation theory,and designs a vertical forest ecological community pattern through calculations and simulations to reduce the risk of local extinction of species in the system.
