城市绿地生态效益测度研究进展

Research Status of Ecological Benefit Measurement of Urban Green Space

城市绿地是国土空间中发挥碳汇功能的重要空间载体,明确城市绿地生态效益及其测度方法相关研究进展,能够为改善生态环境、协助城市可持续发展提供理论依据,对优化城市绿色空间格局、提升碳汇效能具有重要意义。本文基于大量相关科学研究文献,综述了城市绿地生态效益测度基本内涵、现阶段特征、主要方法和未来展望。首先对城市绿地生态效益相关概念展开论述,并总结了当前城市绿地生态测度的主要研究方向;其次对相关国内外研究现状进行追踪与分析,总结了现阶段城市绿地生态效益测度研究的两大特征;随后在此基础上,对城市绿地生态效益测度方法进行了分类,主要分为价值测度法、模型测度法、指标体系法;最后,强调未来研究方向要多关注城市绿地负效应研究,开拓更多生态效益测度方法,加快城市绿地生态效益测度应用,以期进一步推动城市绿地生态环境可持续发展。

Urban green space is an important spatial carrier to play the function of carbon sink in national space.It can provide theoretical basis for improving ecological environment and assisting urban sustainable development,and is of great significance for optimizing urban green space pattern and improving the efficiency of carbon sink to clarify the research progress of urban green space ecological benefits and measurement methods.Based on a large number of relevant scientific research literatures,this paper reviews the basic connotation,current characteristics,main methods and future prospects of the measurement of urban green space ecological benefits.In this paper,what is firstly discussed is the concepts related to urban green space ecological benefits and the current main research directions of urban green space ecological measurement.Secondly,the paper tracks and analyzes the research status at home and abroad and summarizes the two characteristics of the current research on the measurement of urban green space ecological benefits.Then,on this basis,it classifies the measurement methods of urban green space ecological benefit into value measurement method,model measurement method and index system method.Finally,it is emphasized that,in future researches,more attention should be paid to the negative effects of urban green space,developing more ecological benefit measurement methods,and accelerating the application of urban green space ecological benefit measurement,in the hope of further promoting the sustainable development of urban green space ecological environment.
