中亚热带城市近自然人工植物群落构建研究

Study on the Construction of Urban Close-to-nature Plant Community in the Middle Subtropical Zone

城市近自然人工植物群落是以接近自然、模拟自然为设计理念,模拟自然地带性植被,是城市植被人工营造与自然生长的完美结合,对城市的园林建设具有重要意义。宁波与泸州同在中亚热带湿润城市绿化区域,但东西相隔遥远,选取宁波地区与泸州地区的城市园林植物群落共21个典型样地,调查分析其群落的组成和结构,归纳近自然人工植物群落的特征与空间布局,提出近自然人工植物群落构建原则,即生态多样性与适应性原则、功能性原则、景观美学原则,为中国城市近自然人工植物群落的研究与建设提供理论依据。

Urban close-to-nature plant community is close to nature, simulating nature and natural zonal vegetation. It is the perfect combination of the artificial urban vegetation and natural growth, and it is of great significance to the construction of urban garden. Ningbo and Luzhou are both in the middle subtropical humid zone, but are far apart in the east-west direction. The paper selects 21 typical plots of urban plant communities of Ningbo and Luzhou, investigates and analyzes the composition and structure of the communities, summarizes the characteristics and space layouts of the close-to-nature landscape communities. Then it puts forward close-to-nature landscape community building principles, namely the principles of ecological diversity and adaptability, function and landscape aesthetics, which provides a theoretical basis for the study and construction of close-to-nature landscape community.
