摘要
实地调查了太原市12条主要道路的绿化现状。结果表明:按照出现频率来看,常绿树与落叶树比为1∶2.8;乔木与灌木比为1.1∶1,仅从比例来看,太原城市绿化植物配置还不尽合理。另外,通过调查发现太原市道路绿化植物种类单一,植物色彩单调以及空间利用不足。同时,对其不足之处提出相应改进建议:乔、灌、藤、草相结合并且要体现四季性;配置妥当,使植物在不同的季节呈现不同的色彩;乔、灌、藤、草以及地被植物搭配种植以提高空间利用率。从而逐步建立多层次、多结构、多功能的城市绿地植物群落。
The afforestations of twelve main roads in Taiyuan city were investigated. The floristic component was unitary, plant color monotonous as well as spatial use insufficiency. According to the frequency of existence,the ratio of evergreens to hardwoods was 1 ： 2.8,the ratio of arbors to shrubs was 1.1 ： 1,so the plant collocate was not very reasonable. The suggestions of improvement on road afforestation were put forward. Firstly, we should match the proportion among arbors,shrubs, liana and the grasses to manifest the four seasons. Secondly,we should dispose the color plant appropriately to get a colorful year. Thirdly, we could match the component of arbors, shrubs, liana and the cover plants to improve the space structure. Therefore,we could find the city greenbelt plants community in many lavers,functions and structures.
