城市绿地生态效能研究进展

城市绿地是城市生态系统的主要生命支持系统,在维持城市生态平衡与改善城市生态环境质量方面起着重要的作用。城市绿地的建设质量也逐渐成为衡量城市现代化水平的重要因素。随着生态城市的提出与建设,城市绿地生态效能的研究逐渐得到人们的重视,成为诸多学科的研究热点。提高城市绿地系统的生态效能是现代化城市发展的战略方向,也是城市发展达到良性循环的必然趋势。笔者通过对现有文献资料的分析研究,从降温、增湿、固碳放氧、降噪、抗污染、生态保健、生物多样性保护7个方面论述了城市绿地生态效能的国内外相关研究,系统归纳了生态效能的研究方法、城市绿地生态效益规划的构建途径,以期为其深入研究提供理论依据。

Advances in Research on Ecological Function of Urban Green Space

Urban green space, the major life-support system of urban ecosystem, plays an important role in maintaining ecological balance and improving the quality of urban ecological environment.The construction quality of urban green space has gradually become an important factor which is used to measure urban modernization level.With the construction of ecological cities increasingly getting people’ s attention, studies on the ecological function of urban green space have gradually become the focus of many disciplines.Improving the ecological function of urban green space system is both a strategic direction of development of modern cities, and an inevitable trend of urban development to achieve a vir-tuous cycle.In this paper, based on the existing literature data,advances in research on ecological function of urban green space in the world were discussed from seven aspects such as cooling, humidification, carbon fixation and oxygen release, noise reduction, resistance to pollu-tion, ecological health and biodiversity protection.In addition, methods of studying ecological function and ways of constructing ecological function planning of urban green space were summarized to provide theoretical basis for the further research on ecological function of urban green space.
