Abstract:: Yajiang county was used as an example,based on the land use data,elevation data,forestry resources investigation data,soil data,temperature and rainfall data,using spatial analysis method in GIS to analyze the suitable distribution areas of Tricholoma matsutake,conducted a field validation of the results and corrected them.The results showed that Tricholoma matsutake resources were mainly distributed in Hekou town,Bajiaolou town,Gala town,Milong town and so on,and the suitable areas for Tricholoma matsutake′s growth were about 370.08 km2 in Yajiang county,which was accounted for 4.88% of the total county area.Moreover,this study divided the suitable distribution areas of Tricholoma matsutake into three types：suitable areas,the more suitable areas,most suitable areas,and the area of them were 4.32 km2,291.36 km2,74.40 km2,which were accounted for 1.17%,78.73%,20.10% of the total suitable area.The results could provide reasonable basis for Tricholoma matsutak′s protection and utilization.
