城市生态社区的多空间评价体系与应用初探——以广州为例

中国城市生态社区评价研究定性多、定量少,主要原因是评价体系单一,指标可获得性低.本研究提出一个多层次、多目标、多侧重点的多空间评价体系,增强其可操作性.多空间评价体系包括:宏观层面,通过关键的、可获得性高的指标整体评价城市社区的生态性,找到生态得分低的问题地区；微观层面,构建更深入全面、技术性强的指标体系来综合评价重点社区,制定社区生态性改造策略.最后以广州为例,初步探讨多空间评价体系的应用,重点在宏观层面社区的生态性评价,发现得分低于平均水平的社区集中在城市外图层,并对未来微观层面社区评价和规划提出建议.研究对完善生态社区评价体系具有理论意义,对推进生态社区评价的实践具有现实意义.

Study and Application of a Multi-level Evaluation System of Urban Eco-community: A Case Study of Guangzhou

Current research on evaluation of urban eco-community in urban China focuses on construction of indicators and neglects empirical studies which results form a unitary evaluation system and low accessibility of indicators.This research proposes a multi-level evaluation system with multiple objects and contents.It contains two levels.On macro-level,based on key points and high accessible indicators,researchers should calculate Ecological Index of basic geographic units of the whole city and?nd problematic communities.On micro-level,evaluation should be conducted in those problematic communities by more detailed and comprehensive indicators and?eld works.Based on these multi-level evaluations,eco-community planning should be made more effectively.Taking Guangzhou as a case,this paper discusses the application of ecological evaluation on macro-level.It ?nds that those problematic communities are mainly located on outer circle which are the key areas of ecological evaluation on micro-level and community planning.This research has theoretic meaning for study on evaluation system of urban ecocommunity,and it will also help to improve empirical study.
