城市生态绿地建设的理论基础与途径探索

城市生态绿地不仅是城市基础设施，而且更是城市生态环境的重要组成部分，在保障生态平衡、改善城市生态环境、创造良好的人居环境等方面起着其它基础设施无法替代的作用，城市生态绿地建设的质量已经成为衡量一个城市发展状况的重要指标，还是评判是否达到园林城市建设的重要标准。文章阐述了城市生态绿地建设的理论基础有：生态学理论、景观生态学理论；总结出城市生态绿地建设需要遵从的原则有：生态平衡、生态位以及物种多样性，从绿地斑块的构建、绿廊的构建以及城市生态绿地网络系统的构建三个方面提出了城市生态绿地建设的构建途径。

Construction of urban ecological green space and ways to explore the theoretical basis

Urban ecological green space is not only the city infrastructure, but also is an important part of the city ecological environment. It plays an irreplaceable role in protecting ecological balance, improving urban ecological environment and creating a good living environment. The quality of urban ecological green space construction has become an important indicator of of a city＇s development condition and an important criterion to judge whether it reaches the level of the garden city construction. The article elaborates the theoretical basis of urban ecological green space construction： ecological theory, landscape ecological theory and sums up urban ecological green space construction principles：ecological balance, ecological niche and species diversity. In addition, the article puts forward the ways of city ecological green space construction from the aspects of green plaque build, green gallery building and urban ecological green network system.
