本文分析了目前城市绿地群落构建中存在的问题,讨论了绿地群落的特征和合理结构,并探讨了基于生物多样性的城市绿地群落构建途径,即开发以地带性物种为核心的多样化绿化植物品种,培育苗木产业;模拟地带性群落的结构特征,遵从“生态位”原则,构建乔灌草复层群落结构;适当恢复和重建城市近自然群落,创建野生动植物的适宜栖息地。 This paper analyzes the existing problems in the construction of urban greenland communities, discusses the characteristics and rational structure of greenbelt communities, and discusses the approach to the construction of urban greenbelt communities based on biodiversity, namely the development of diversified green plants with zonal species as the core. Varieties, nurturing nursery stock industry; modeling the structural characteristics of zonal communities, complying with the principle of “nibitity”; constructing a community structure of trees and shrubs and grasses; properly restoring and rebuilding urban near-natural communities and creating suitable habitats for wildlife.
