| 摘 要： | 延药睡莲（Nymphaea nouchali Burm. f.）是海南原产的睡莲属原生种和珍稀水生花卉,具有重要的观赏、生态价值及一定的药用和食用价值,也是开展热带睡莲新品种培育的良好材料。为了全面了解海南岛延药睡莲的资源分布及保护现状,为其科学保护和有序利用提供参考依据,对延药睡莲资源进行多次野外调查,记录观测延药睡莲分布、生境条件及生存状况。结果表明：延药睡莲在海口、万宁、昌江、三亚、乐东等市县有自然分布,各分布点野生植株数量及生长势不一,其中三亚甘什岭分布点延药睡莲的生长状况较好,而乐东球港村分布点的植株数量最多;延药睡莲主要生长于水深0.2~1.6 m的静态水体中,对水质和水位等生活环境的要求较高,极易因环境因素的干扰而导致种群规模减少乃至消失;延药睡莲的自然分布点大多处于未保护状态,受外来生物入侵和人为因素干扰严重,野生数量稀少,已处于濒危状态,亟待保护。

| Abstract: | Nymphaea nouchali Burm. f. is a native species of water lily and a rare aquatic flower in Hainan. It has important garden ornamental, ecological protection and certain medicinal and edible value, and is also an excellent material for breeding new tropical water lily varieties. In order to fully understand the resource distribution and conservation status of N. nouchali Burm. f. in Hainan Island, and to provide reference for scientific conservation and orderly utilization of the plant, this paper carried out several field investigations on N. nouchali Burm. f. resources in Hainan Island, recorded and observed the distribution, habitat conditions and living conditions of N. nouchali Burm. f. resources. N. nouchali Burm. f. was naturally distributed in Haikou, Wanning, Changjiang, Sanya, Ledong and other cities and counties, but the number and growth potential of wild plants in each distribution point were different. The growth condition of N. nouchali Burm. f. was better in Ganzaling distribution point of Sanya, and the number of plants in Qiugang village of Ledong was the largest. N. nouchali Burm. f. mainly grows in static water with a water depth of 0.2?1.6 m, and has high requirements on living environment such as water quality and water level. It is easy to reduce or even disappear due to the interference of environmental factors. Most of the natural distribution sites are not protected, and the wild plants are seriously disturbed by exotic biology invasion and human factors. The wild number is rare, and they are endangered and in urgent need of protection. |
