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
