Abstract: Cathaya argyrophylla is a China endemic and rare species distributed in Sichuan,Guizhou,Hunan and Guangxi Provinces．This leads to four geographic distribution centers of this species:Daloushan, Yuechenglin．Bamianshan and Dayaoshan．All Cathaya argyrophylla forests are normally mixed and there are seven Cathaya community types．Cathaya argyrophlla is one of the dominant species in these types,but its natural regenerations are poor．Cathaya argyrophylla is theatened by the invasion of broad-leaved species and is likely to be replaced by them during the succession．To preserve Cathaya argyrophylla,two effective methods are suggested in the present paper:the preliminary thinning of the broad-leafed species and the transplanting of the sapling of Cathaya argyrophylla in gaps．
