摘要
广东山区野生芳香植物资源丰富,初步统计共有111科311属763种(含变种),包含乔木、灌木、草本和藤本4种生活型。区系成分分析显示:该地区芳香植物科的气候带分布类型以热带至亚热带分布(主产热带)和热带至温带分布(主产热带亚热带)成分为主,分别有29科(占26.1%)和38科(占34.2%),主要集中于木兰科、樟科和芸香科等10个科;属的地理分布区类型多样,以热带成分为主(187属,占60.1%),同时兼有大量的温带成分(99属,占31.8%)。研究发现,本区具有较高观赏价值和园林开发前景的特色芳香植物有372种,隶属66科150属。本文对它们的应用前景与应用形式作初步探讨,并对其开发利用与保护提出建议。
The resources of wild aromatic plant in Guangdong Mountains were very rich. Our study showed that there were 763 species of wild aromatic plants from 111 families and 310 genera, including trees, shrubs, herbaceous and lianas. The distribution area types of this aromatic plant flora were abundant. At the family level, the most abundant types of climatic zone were the ＂tropical to subtropical elements＂ （29 families） and the ＂tropical to temperate elements＂ （38 families）, which made up 26.1% and 34.2% of the total numbers of families respectively. There were 10 families with the most abundant species of aromatic plants, i.e. Magnoliaceae, Lauraceae and Rutaceae, etc. At genus level, all the 310 genera of aromatic plants can be classified to 13 geographical distribution types; and the genera of tropical areal-types （187 genera） make up 60.1%, taking a predominated position, while those of temperate ones （98 genera） account for 31.8%. Finally, the status and utilization as well as application prospects of the landscaping fragrant plants in Guangdong Mountains were discussed in this paper. We found that there were about 372 species of aromatic plants with high ornamental and landscaping value in this flora. Some suggestions on the utilization and application of the wild aromatic plant resources were given.
