Taking local wild gray Polyporus umbellatus and cultured Armillaria as the material，the appropriate altitudes of semi-wild cultivation of Polyporus umbellatus were selected by cultivating areas ranging from 600～800 m，800～1 000 m，1 000～1 200 m to 1 200～1 400 m.The results showed that the yield and economic benefit of Polyporus umbellatus planted at 800～1 200 m altitude were better than the other groups.The yield production of those growing in forest area at 1 000～1 200 m,and 800～1 000 m altitudes were significantly higher than that of 1 200～1 400 m and 600～800 m altitudes,with nearly doubled economic benefit.Therefore，the suitable cultivation area of semi-wild Polyporus umbellatus should be within the scope of hilly areas at 800～1 200 m altitude.
