藏药狭叶红景天的资源现状调查

为了更好地了解藏药狭叶红景天的资源现状,分析野生狭叶红景天的适生生境,保护狭叶红景天的野生资源,促进狭叶红景天资源的可持续利用。该文采取走访与野外样方相结合的调查方法以及蕴藏量估算法对四川、青海、甘肃和云南4个省16个县的狭叶红景天野生资源进行了调查。结果发现,4个省的野生狭叶红景天种群密集程度有很大的差别,很多地区野生资源蕴藏量逐渐下降。根据调查结果估算,4个省16个县当前狭叶红景天野生资源蕴藏量约1 100 t,目前四川省的野生狭叶红景天资源量最大。同时,狭叶红景天具有一定的生态价值,调查中发现在四川省阿坝藏族羌族自治州红原县建有防沙治沙狭叶红景天基地。通过调查,为狭叶红景天资源的开发及可持续利用提供了科学依据。

Resource investigation about Tibetan medicine Rhodiola kirilowii

The investigation aims to better understand the resource status of Rhodiola kirilowii, analysis the suitable habitat of wild Rh. kirilowii and protect the wild resources of Rh. Kirilowii, promoting the sustainable utilization of Rh. kirilowii resources. In this paper, we investigated the wild resources of Rh. kirilowii in 16 counties of Sichuan, Qinghai, Gansu and Yunnan by means of investigation and sampling investigation combined with interview. The results showed that the population densities of wild Rh. kirilowii in 4 provinces were very different and the reserve of wild resources decreased gradually in many areas. According to the survey results, the current total reserve of Rh. kirilowii in four provinces was about 1 100 t. The reserve of wild Rh. kirilowii in Sichuan province was the largest. Simultaneously, the Rh. kirilowii had a certain ecological value. We found that a sand control base with planting Rh. kirilowii was set up in Hongyuan County of Sichuan Aba Tibetan and Qiang Autonomous Prefecture. The investigation provides a scientific basis for the development and sustainable utilization of Rh. kirilowii resources.
