摘要
采用景观多样性的分析方法,探讨了4种景观类型:植物群落组成、种数、层次、色彩在武汉道路绿化带上的应用以及对道路绿化带的影响.结果表明:从植物群落生活型组成上分析,武汉市各道路绿化带植物景观多样性差异不大,整体组成单一,类型较少;从种数上,景观多样性指数最高,说明不同地段道路绿化带植物种数差别较大;从层次上看,多样性指数偏高,说明不同路段绿化带层次上差异较大;而色彩的景观优势度最大,说明道路绿化带中某一类色彩占优势.
Four types of the greenbelt landscape ： the composition of the plant community, the number of the species, the level as well as the color of plants are considered for the study of the landscape diversity, whose application and influence on the road greenbelts are also analyzed. The result shows that the landscape diversity of the road greenbelts in Wuhan is of little difference on the analysis of the composition of the plant community, so the composition of the whole is simple and the type is few; But the diversity index is the biggest on the analysis of the species, which shows that there are much difference on species for the different road greenbelts in Wuhan; The diversity index is a bit high from the point of the level, which shows that there is difference between different parts of the greenbelts; As with the color, the predominance is the highest, so one type of color is dominant among those color of the greenbelt.
