ABSTRACT

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.
