城市绿地生态功能综合评价体系研究的新视角

在对城市绿地生态系统评价研究中人们关注的焦点主要集中在城市绿地为人类提供的生态服务功能,而忽视绿地自身运转功能。构建科学、完善的城市绿地生态系统功能综合评价体系,对于重新认识城市绿地生态系统的综合功能,提升绿地建设和管理水平具有重要的意义。本文分析了目前城市绿地生态系统功能评价容易忽略的绿地数量和面积与生态功能的关系、人工绿地生态系统与自然生态系统生态功能的差异、对城市绿地特殊生存环境和后期科学管护的忽视、只重视城市绿地功能和价值而忽视建设和管护成本以及绿地建设的内涵在城市园林绿化中被曲解等几个问题,在此基础上从绿地生存环境优良性、绿地健康状况、绿地综合效益评价、居民对绿地感知认识出发,探索并构建城市绿地生态系统功能综合评价体系,以反映城市绿地与城市环境之间的适应性和绿地是否能有能力提供足够的生态服务以及居民对绿地生态效益、景观效益、社会经济效益的感知和认同,旨在为城市绿地规划、建设和管护提供有力支撑和指导,更好发挥城市绿地生态系统综合效益。

New Perspective of Comprehensive Evaluation Research on Urban Green Space Ecosystem

The attention of research focused on ecosystem services provided that urban green space for the human on the evaluation of urban green space ecosystem formerly,that ignored the own operation of ecosystem itself construct a scientific and perfect evaluation system of urban green space,it has great significance to reacquaints function of the urban green space system and promote the function and benefit of green ecosystem.On the analysis of some problems,such as the relationship between the number,the area of green space and ecological features,the function’s differences between artificial ecosystems and natural ecosystems of urban green space,ignored the special living environment of urban green space and post-scientific management and protection,only attach importance to the function and value of urban green space while ignoring the cost of construction and management and protection,also distorted the content of green building in the urban landscape and so on,which neglected in urban green space’s function evaluation,from the fine state of green living environment,green health,comprehensive benefit evaluation,the residential awareness and understanding of green space,explore to build urban green ecological comprehensive evaluation system,reflect adaptability between urban green space and urban environment,green space is whether or not have the ability to provide enough ecosystem service,the perception of the residents in ecological benefit,landscape benefit and social economic benefits.In order to provide powerful support and guidance for urban green space system planning,construction and management,also play better comprehensive benefits for urban green ecosystem.
