对广州华侨新村低密度住宅区庭院树木的组成、结构、空间格局、树木与生境的关系，以及私人庭院树木与公共绿地的不同特点进行了研究。结果表明：华侨新村庭院树木的种类多样性很高，共有１１４个树种。与广州城市行道树相比，华侨新村的乡土树种和果树比例较高。在调查的树木中８４．７５％的树木没有结构损伤现象，只有１．５％的树木生长较差。私人庭院内的树种较为分散，有４５种树木为每个庭院仅一棵的单生种，有６７．１％的庭院其树种在５种或以上。树木在街道的空间分布则有相对集中的趋势。庭院的大小是影响树木生长的重要条件，在有限空间的庭院内种植过多的树木是造成树木和环境关系紧张的重要原因。
The composition, structure, spatial pattern, the relationship between trees and habitats and the different characteristics of private courtyard trees and public green spaces were studied in the courtyard of low density residential area in Huaqiao Village, Guangzhou. The results showed that the species diversity of the trees in the overseas Chinese village was very high with a total of 114 tree species. Compared with the urban road tree in Guangzhou, Overseas Chinese Village has a higher proportion of native tree species and fruit trees. Of the trees surveyed, 84.75% had no structural damage and only 1.5% had poor growth. The trees in the private courtyards are scattered, with 45 species of only one single species per yard and 67.1% of the gardens with 5 or more tree species. The spatial distribution of trees in the streets tends to be relatively concentrated. The size of the courtyard is an important condition affecting the growth of the trees. Too much trees in the courtyard with limited space is the main reason that causes the tension between the trees and the environment.
