海南热带雨林国家公园华石斛附生习性及生境分布特征
Epiphytic Habits and Habitat Distribution Characteristics of Dendrobium sinense in National Park of Hainan Tropical Rainforest
摘要
Abstract
Dendrobium sinense,a species endemic to Hainan,is often used as a traditional medicine by the Li people in Hainan.It is rich in medicinal active ingredients but is in an endangered state due to environmental influences.This study investigated the living habits and habitat distribution characteristics of D.sinense in Hainan Tropical Rainforest National Park through field measurement.The results showed that D.sinense was mostly distributed at an angle of 40° to 60°,usually facing southwest,and at a height of 4 to 6 meters.D.sinense plants were more frequently found on trees with a diameter at breast height of 40 to 60 cm.In different habitats,the plants were more abundant on slopes with a gradient of 0 to 15° and facing east.Redundancy analysis indicated that temperature and humidity were the key environmental factors affecting the growth habits of D.sinense.The research results provide a theoretical basis for the future conservation and utilization of D.sinense resources in different regions.关键词
