植物区系分析在湛江城市园林植物规划中的应用

Application of the Flora Analysis in the Design of Urban Greening Plants in Zhanjiang City

城市植被的组成特征是确定城市绿化性质和特色的科学依据。通过对湛江市城市植被进行植物区系分析,结果表明植物区系的地理成分以热带成分占绝对优势,各类热带分布属共449属,占总属数的81.49%。城市园林植物种的来源多样化,以热带亚洲分布类型最多。从而提出湛江市城市绿化特色应定位于营造热带园林,城市园林植物的规划方向应以热带植物为主。

The characters of combination of urban vegetation are the scientific evidence for shaping the character of urban greening. The paper studied the urban vegetation by flora analysis in ZhanJiang City. The result showed that the tropical elements took the dominant position in flora geography; all 449 genera tropical elements took 81.49 % of the total. The source of the urban plants was multiplex, and most of them belonged to the Tropical-Asia distribution. So the character of the urban greening in Zhanjiang should be confirmed as constructing the tropical landscape, and the design of the urban greening plants should tend to the tropical plants.
