[Objective] To research the effects of soil physicochemical factors on the distribution of CORDYCEPS. [Methods] Literature survey,Interview and sampling analysis were carried out in the four streets and seven villages in Hezuo City of Gannan Tibetan Autonomous Prefecture( 102°47’51″- 103°22’00″ E,35°18’50″ N). Soil layers 0- 5,5- 10,10- 15 and 15- 20 cm in 21 sampling sites were analyzed.The plant number of CORDYCEPS was recorded,as well as thevegetation component,plant coverage,density and height,distribution status and growth status. [Results]In different soil layers,pH,TN,TP and AP had no significant differences; while WC,OM,TK and AK showed extremely significant differences. In soil layer 5- 10 cm,WC significantly affected the distribution of CORDYCEPS; while pH and TK had extremely significant impacts. The number of CORDYCEPS was the maximum in soil layer 5- 10 cm. In the first principal component,TP was the major factor affecting the population distribution of CORDYCEPS. In the second principal component,pH was the major factor. [Conclusions] CORDYCEPS had strict requirements for soil layer,TP and soil acidity-alkalinity. At the same time,WC,OM and TK also affected the distribution of CORDYCEPS.

Soil layers 0-5, 10-10-15 and 15-20 cm in 21 sampling sites were analyzed. The plant number of CORDYCEPS was recorded as as well as the gain component, plant coverage, density and height, distribution status and growth status. [Results] In different soil layers, pH, TN, TP and AP had no significant differences; while WC, OM, TK and AK showed extremely significant differences. In soil layer 5- 10 cm, WC significantly affected the distribution of CORDYCEPS; while pH and TK had extremely significant impacts. The number of CORDYCEPS was the maximum in soil layer 5- 10 cm. In the first principal component , TP was the major factor affecting the population distribution of CORDYCEPS. In the second principal component, pH was the major factor. [Conclusions] CORDYCEPS had strict requirements for soil layer, TP and soil acidity-alkalinity. At the same time, WC, OM and TK also affected the distribution of CORDYCEPS.
