1 加强树种调查与树种发展规划,丰富生物多样性 加强城市园林绿化树种调查与树种发展规划,是每个地区、每个城市绿化建设的一项至关重要的工作。它不仅是建设生态园林速度快慢、质量高低、效果好坏及成功与失败的关键所在,而且是城市绿化生态化总体规划与建设中一个非常重要的环节。 上海植被区系成分,按《中国植被区划图》划归中亚热带常绿阔叶林地带,松江区的佘山和金山区的大金山岛现存的半自然状态的植物区系成分,基本上反映了本地区地带性植被类型的基本特点。但是城市环境中的植被分布现状与上述结论并不符合。调查发现,上海常用绿化植物为382种,其中乔
1 to strengthen the investigation of species and tree species development planning, enriching biodiversity Strengthen urban landscape tree species survey and tree species development planning is a green building in each region and each city is a crucial work. It is not only the key to the construction of eco-garden’s speed, quality, effectiveness and success and failure, but also a very important link in the overall planning and construction of urban greening and ecology. The fauna flora of Shanghai is classified into the subtropical evergreen broad-leaved forest zone according to the “Chinese Zoning Plan”, and the existing semi-natural flora of Sheshan and Jinshan District in Songjiang District basically reflects The basic characteristics of zonal vegetation types in this area. However, the distribution of vegetation in urban environment does not accord with the above conclusion. The survey found that Shanghai commonly used for 382 kinds of green plants, including Joe
