Abstract: The growth , timber quality and fruits of 13 provenances of Alnus cremastogyne was tested to study the geographical variation of Alnus cremastogyne and its tendency .The climate ecology foundations for the geographical variation and divided the provenance areas were discussed .The results implied that there was significant correlation between provenance growth characteristics of Alnus cremastogyne and ecological gradient axis (EGA).The analysis of single ecological factor showed that the provenance growth quantity of Alnus cremastogyne changed with the longitude and altitude .There was no significant correlation between the bio-substance production and fiber length of single plant and longtitude and latitude .There was significant correlation between the basic density of timber and longitude .Judging by the EGA of Alnus cremastogyne provenance and the growth status of the experimental forest , there're three provenance areas of Alnus cremastogyne , namely , northwest Sichuan , central Sichuan and south Sichuan .[ Ch , 1 fig .4 tab .11 ref .]
