采用样地调查法,对兰溪市区内的公园、道路、山林、水体等绿地植物种类及城市绿地半自然环境下自然生长的地被景观进行实地调查。结果显示:兰溪市城市绿地中有植物64科150种,裸子植物4科12种,藤本植物4种(不包含非人工种植的野生地被植物种类)。建成区主要公园绿地植被群落较为人工化,主要树种较为单一,可以划分为12个群落类型;建成区主要的26条道路应用的绿化树种仅有8种;城市绿地中地被植物群落类型30种。存在城市绿地中植物种类丰富度不够,植物景观特色单一,乡土植物应用薄弱等问题。
A sample survey was conducted to investigate the types of green plants such as parks, roads, forests and waterways in Lanxi city and the landscape of natural vegetation that grows naturally under the semi-natural environment of urban green space. The results showed that there are 150 species of 64 families, 12 gymnosperm families, 4 families of gymnosperms and 4 species of liana (not including non-artificial wild ground cover plants) in the urban greenland of Lanxi City. The vegetation communities of the main park greenland in the built-up area are more artificial, the main species are single and can be divided into 12 types of communities. Only 8 kinds of greening trees are used in the main 26 roads in the built-up area. There are 30 species of vegetation in the urban greenland, . There are some problems such as insufficient plant species richness in urban green space, single plant landscape characteristics and weak application of native plants.
