摘要
园林树木是构成城市绿地的主要植物材料,也是发挥城市绿地功能效益的主要植物群落体,城市森林作为城市生态绿地系统的重要组成部分,突出强调了乔木在城市绿地中的骨架和主体地位,它不仅具有多种生态功能,而且对改善日益恶化的城市生态环境具有不可替代的作用。在城市森林规划中,景观格局分析是优化城市森林空间结构和充分发挥城市森林生态功能的重要手段和途径。文章分析了城市森林的内涵;阐述了城市森林景观格局分析的研究方法;提出了基于景观格局分析的城市森林规划的过程,探讨了城市森林的景观分类、景观指数的选取要点及景观格局的优化重点;展望了城市森林规划的发展趋势。
Garden trees are main plant materials to constitute city green space and the main body of plant community to play city green function benefit.Urban forest is an important component of city ecological green space system and highlights the tree＇s dominant position in city green space.It has a number of ecological functions and plays an irreplaceable role in improving the worsening urban ecological environment.In urban forest planning,landscape pattern analysis is an important mean and way of optimizing the spatial structure and playing fully the urban forest ecosystem functions.This paper analyzes the meaning of urban forest,elaborates the research methods of urban forest landscape pattern analysis,puts forward the urban forest planning steps based on landscape pattern analysis,discusses the landscape classification of urban forest,key points of landscape metrics selection and landscape pattern optimization,and analyzes the prospects of the development trend of urban forest planning.
