| 中文摘要: |
| 采用第4 次全国中药资源普查野生重点中药资源调查方法对海南昌江黎族自治县野生中药资源进行调查，通过海拔分布范围和出现频率分析了该县药用植物的分布状况及资源丰富度。结果表明，该县药用植物共179种，其中国家重点中药材42 种，海南重点药材20 种，少数民族民间常用的中草药117 种，表明该县不仅药用植物资源较丰富，而且民间常用中草药知识也较为丰富。药用植物的分布随海拔高度的变化相应地分为广幅种（9种，5%）、中幅种（48种，26.8%）和狭幅种（122种，68.2%），表明该县大多数的药用植物多为狭幅种。进一步分析表明，该县大多数药用植物种类（125 种）的出现频率与分布范围呈正相关，物种的出现频率越高，分布的范围越广；反之，分布的范围越窄。在对药用植物进行开发利用的同时，也要大力加强对野外珍稀濒危药用资源的保护。 |
| 英文摘要: |
| Using the method of the fourth survey of the national Chinese medical resources, the wild Chinese medical plant resources Changjiang county of Hainan were investigated. The distribution patterns and species richness of the wild Chinese medical plants were explored according to their altitudinal distributions and occurrence frequencies. Results showed that the Chinese medicinal plants in Changjiang country were attributed to 179 species, including 42 species of national key Chinese medical plants, 20 species of Hainan key Chinese medicinal plants and 117 species of Chinese folk herbal plants in the Li minoritie. This indicated that both the medical plant resources and folk herbal knowledges in this country were rich. The medical plants in this country could be classified into widely distribution species (9 species, 5%),generally distribution species (48 species, 28.6%) and narrowly distribution species (122 species, 68.2%), according to their distributions along the altitude. Occurrence frequencies of 125 plant species were positively correlated with their distribution ranges, indicating that the higher the plant occurrence frequency, the wider their distribution ranges. The result also indicates that it is needed to enhance the protection of rare and endangered wild medicinal resources when we develop and utilize the wild medical plants. |
