城市绿化植物分析

以海南城市的绿化树种结构及其组成成分和美学布局的研究为例，探讨城市绿化树种的分析研究方法和意义，采用树种的相对密度、相对存在度、相对覆盖度之和表示城市绿化树种的重要值，并从植物区系的角度分析城市绿化人工植被的特性与地区特性的关系。同时指出海南城市的绿化树种选择的原则是正确的，但在城市绿化的合理布局方面，除了突出主题之外，仍需以多种形式来点缀。

ANALYSIS OF THE PLANT FOR URBAN AFFORESTATION

The method and significance of analysis of the plant species for urban afforestation is studied by analyzing the following three aspects:the structure of plant species,the floristic components and the aesthetical pattern of the plant species in, Hainan cities.The important value of plant species for urban afforestation is described by taking the sum of the relative density,the relative presence and the relative coverage of the plant species, and the relationship between the characteristic of the artificial vegetation of urban afforestation and region is also analysed by studing floristic components of plants in cities.However,it is pointed out that the principle of urban afforestation is right in Hainan,and prominence should be given to the theme,and various patterns of the plants should also be embellished for the rational distribution of the afforestation plants in Hainan.
