: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。 : The composition, structure, the relationship between trees and habitats, the different characteristics of garden trees and public green spaces, the different characteristics of the trees in old and new residential quarters were studied in the courtyard of Xinhepu District, Dongshan, Guangzhou. The results showed that the species diversity of trees in Xinhepu plot was very high, the distribution of tree species was more dispersed, medicinal trees and fruit trees accounted for the vast majority, while the shade plants were relatively smaller. Tall arbor accounts for a large proportion, so the space competition more sharp, but a reasonable hierarchy to some extent cushioned this contradiction. Tensions and the lack of long-term planted garden trees are the main causes of the tension between trees and habitats.
