摘要
为了进一步了解长沙市岳麓区落叶行道树布局的有关问题，笔者主要通过实地调查和数据收集的调查方法，对其进行了初步调查与研究，并对所得资料数据在树种多样性及分布特点、水平绿化分布结构、垂直结构及配置方式3个方面进行了整合与分析，研究结果表明：岳麓区落叶行道树树种偏少，所占比例偏低；某些路段的落叶行道树并未按规范正确栽种与布置，略显凌乱，影响城市美观；有关园林部门未注意落叶行道树的常年管理；落叶行道树配置缺乏自然层次，导致景观单调。在此基础上，笔者提出了相应的改进措施，即适当引入适合长沙市生长环境的外来落叶行道树树种并适当提高落叶行道树所占比例；制订有关落叶行道树的规范，加强落叶行道树的规划与常年管理；注重落叶行道树配置的自然层次与丰富层次。落叶行道树作为城市行道树的一部分，近年来受到越来越多的重视，因此，长沙市岳麓区在进行行道树布局时有必要注重落叶行道树的科学合理布置。
Abstract
In order to further understand the related problems of deciduous tree ’s layout of Yuelu District of Changsha City,preliminary investi-gation and study were carried out by on-the-spot investigation and data collection methods .The obtained data were analyzed from three aspects of the species diversity and distribution characteristics, the greening distribution structure,the vertical structure and configuration mode .Results showed that deciduous trees in Yuelu District were relatively less, and its percentage was low.Deciduous trees in some areas were not planted properly according to specifications and layout, which was a bit messy and affected the beauty of the city.The botanical garden department did not pay attention to the perennial management of deciduous trees, configuration of the natural layer of dangerous trees were lacked, which led to single landscape.Based on these, corresponding improvement measures were put forward , such as properly introducing foreign deciduous tree species to Changsha City, enhancing the proportion of deciduous trees, establishing specification for deciduous trees, strengthening the planning and management of perennial deciduous trees, and paying attention to the natural level and rich level of the configuration of deciduous trees.As part of the urban street trees, deciduous tree had been paid more and more attentions in recent years.Therefore, it was necessary to pay attention to the scientific and reasonable layout and deciduous trees in Yuelu District of Changsha City.
