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.

摘要: 华石斛Dendrobium sinense是海南特有种,常作为海南黎药使用,富有丰富的药用有效成分。因受到环境影响,华石斛种群多处于濒危状态。本研究通过实测法研究海南热带雨林国家公园华石斛的生活习性及生境分布特征。结果表明,华石斛附生角度在40°~60°间分布较多,通常朝向为西南方向,附生高度在4~6 m区间。附生树种胸径在40~60 cm的华石斛植株分布较多。在不同生境中坡度为≤15°区间、坡向为东方向的华石斛植株较多。冗余分析显示环境因子中温度、湿度是影响华石斛生长习性的关键因子。研究结果为不同地区华石斛资源保护及利用提供理论依据。
