Abstract: Distribution characteristics and aboveground biomass of Athyrium multidentatum were studied for the reasonable suggestion of its sustainable utilization. The results showed that: 1) In Liangshui Nature Reserve, A. multidentatums height, density and aboveground biomass decreased along the increase of elevation. 2) The aboveground biomass of A. multidentatum was significantly different in various forest types, and it in line with sprucefir valley forestriparian miscellaneous forestmanmade forestcostata birchKorean pine forestTiliaKorean pine forestscales spruceKorean pine forestlarch valley forestsprucefirKorean pine forestbirch valley forestmountain Populus davidiana forestMongolian oakKorean pine forest. 3) In different forest types, A. multidentatum aboveground dry weight was also dissimilar. The highest gross reserve was 226 420.1 kg appeared in sprucefir valley forest (496.1 hm2); the lowest gross reserve was 0 appeared in Mongolian oakKorean pine forest (10.0 hm2), and the order of gross reserve was sprucefir valley forestcostata birchKorean pine forestTiliaKorean pine forestriparian miscellaneous forestmanmade forestsprucefirKorean pine forestscales spruceKorean pine forestmountain P. davidiana forestbirch valley forestlarch valley forestMongolian oakKorean pine forest. 4) With the premise of protecting broadleaved Korean pine forest ecosystem, we suggest that choosing sprucefir valley forest, larch valley forest, riparian miscellaneous forest, birch valley forest and manmade forest as the regions for resource utilization of A. multidentatum.
