摘　　要：木本植物区系是支撑雷州半岛区域生态安全的极其重要的森林资源,调查分析其特征可促进该区域森林资源的保护和可持续利用。2011年9月—2013年8月期间采用线路踏查法,开展了雷州半岛野生木本植物区系标本采集与鉴定。记录雷州半岛野生木本植物区系102科317属564种(包括种下等级,下同),包括裸子植物3科3属4种和被子植物99科314属560种;乔木树种有55科118属191种,灌木种类有69科174属292种,木质藤本有31科56属81种;热带区系特征显著;人类开发活动是该区系过去50年间最主要的驱动力。The woody flora of Leizhou Peninsula supports eco-safety as one of important forest resources in the region, and its survey and characteristic analysis aims to promote its conservation and sustainable utilization. The travel investigation method was adopted for the wild woody flora specimen collection and identification in Leizhou Peninsula during Sept.2011-Aug.2013. The wild woody flora records 102 families 317 genera 564 species, including Gymnospermae 3 families 3 genera 4 species, Angiospermae 99 families 314 genera 560 species, arbor tree 55 families 118 genera 191 species, shrub 69 families 174 genera 292 species, and woody climbers 31 families 56 genera 81 species. This is characterized by its dominant tropical components, and driven mainly by the human activities over the past 50 years.
