摘要:

以《中国珍稀濒危保护植物名录(第一册)》、《中国植物红皮书-稀有濒危植物(第一册)》和《国家重点保护野生植物名录(第一批)》为依据,整理发现海南乐东县有国家重点保护植物31种,隶属于26科29属,其中被子植物21科23属23种,裸子植物4科4属4种,蕨类植物1科2属4种。分析结果得出,海南乐东县国家重点保护植物区系具明显的热带属性,在中海拔650~750 m、坡度20°—30°之间种类较多。本研究旨在通过对乐东县国家重点保护植物资源及分布特征进行研究,为乐东县内保护植物资源的规划管理及科学保护提供理论依据。

Abstract:

According to The List of Rare and Endangered Plants in China (volume 1), The Rare and Endangered Plants in China Plant Red Data Book - (volume 1) and The National Key Protected Wild Plants List (first batch), we found that there are 31 species of national key protected plants in Ledong County of Hainan, which belong to 26 families and 29 genera, including 21 families, 23 genera and 23 species of angiosperms, 4 families, 4 genera and 4 species of gymnosperms, 1 family, 2 genera and 4 species of ferns. The study shows that the flora of the national key protected plants in Ledong County has obviously tropical properties, and distributes mainly at the middle altitude of 650-750 m and slope of 20°-30°. The purpose of this study is to provide a theoretical basis for planning management and scientific protection of national key protected plant resources in Ledong County by studying the distribution characteristics of the resources.

Key words: Ledong County of Hainan, national key protected plant, plant resources, distribution characteristics, flora analysis
