城市森林是城市有生命的生态基础设施,是城市生态安全的重要保障。文中从城市连片发展、污染跨区域传播、生态系统破碎、休闲空间不足、外来景观入侵、伪生态行为泛滥等6个方面分析了中国城镇化发展过程中与生态环境相关的突出问题,提出要树立城市森林生态系统、城乡生态景观一体、城市群环境共同体、地域乡愁生态景观、城市森林百年大计的森林城市建设观念,改正破坏河岸自然植被、全面硬化河道、净化城市林地落叶等伪生态行为。最后,针对城市森林建设的5个方向提出了14条具体建设意见。

A Community of Common Environment for City Cluster and Strategy of Urban Forest Construction in China

Being the living urban eco-infrastructure, urban forest is an important guarantee to urban ecological security. This paper analyzed the key problems of ecological environment in the process of urbanization development in China in terms of continuous urban development, cross-region pollution spread, ecosystem fragmentation, lack of recreational space, alien landscape invasion and the proliferation of pseudo-ecological behavior. We came up with five concepts of the urban forest construction, including establishment of urban forest ecosystem, integration of urban and rural landscapes, a community of common environment for urban cluster, local nostalgia ecological landscape, and the long-term goal of urban forest development. It was suggested to correct the pseudo-ecological behaviors such as the destruction of natural riparian vegetation, hardening river bed and cleaning up of the fallen leaves in city woodland. Finally, we put forward 14 specific suggestions based on the 5 concepts for the construction of urban forest.
