摘要
以怀化市城市道路绿地为研究对象,调查和分析了怀化市道路绿地的园林植物应用与园林景观现状,并测定了园林绿地的生态因子。结果表明:怀化市建成区主干道路绿地现应用了木本类园林植物43种;道路绿地景观总体水平较低,绿地所发挥的生态效益有限;绿化好的正清路段的氧气含量、温度、空气湿度等生态环境条件与火车站、河西、三角坪、中心市场等相比,更适于人类活动;怀化市道路绿地中所存在的主要问题有:道路绿地断面形式不合理、道路景观地方特色不足、植物群落结构不稳定、绿带生态效益不显著。并提出了从城市总体规划、道路规划、植物规划几方面入手,全面提高道路绿地绿化质量的建议。
Regarding the greenbelts of urban road in Huaihua City as research subject,the landscape plants and landscape status of the greenbelts were investigated and analyzed,and the ecological factors were determined.The results showed that,there were only 43 species of woody landscape plants applied in the greenbelts.The overall level of landscape was lower and the ecological benefit contributed by the greenbelts was limited.The eco-environmental conditions such as oxygen content,temperature and air humidity of Zhengqing road with good greening were better than that of the roads of railway station,Hexi,Sanjiaoping,centre market and so on.The main shortcomings of the road greenbelts were reasonless layout of road green section,inadequate local characteristics of road landscape,unstable plant community structure and low ecological benefit of road greenbelts.Furthermore,some suggestions to improve the quality of greening in road greenbelts were proposed from the aspects as urban overall planning,road planning and plants planning.
