广州新河浦小区庭院树木特征及其与环境空间的关系

Characteristics of Garden Trees in Xin Hepu District in Guangzhou and its Relation with the Environmental Space

:对广州老城区东山新河浦小区庭院树木的组成、结构、树木与生境的关系 ,以及庭院树木与公共绿地的不同特点 ,新旧住宅区庭院树木的不同特点等进行了研究。结果表明 :新河浦小区庭院树木的种类多样性很高 ,树种的分布较分散 ,药用树和果树占绝大多数 ,而树荫植物的比例则相对较小。高大乔木所占比例大 ,所以空间争夺较尖锐 ,但合理的层次结构在一定程度上缓冲了这一矛盾。空间紧张且缺乏长远规划地栽种庭院树木是造成树木和生境关系紧张的重要原因。

Characteristics of trees in front of gardens is studied in this paper.Data on habit conditions,species composition,tree structure and performance of the trees are collected through a field survey of front gardens of the district.Result shows that the biotic diversity is quite high,and is strongly represented by medicine and fruit trees,but weakly by shade trees.Indigenous species are overwhelmingly preferred.The main problem is the ill effect of cramping so many trees within limited niches and lack of long-term prospects although it has been well cushioned to a certain extent by the reasonable arrangement structure.
