摘　　要：本文对于长白山南坡高山半寒漠植被中大面积匍匐生长在地表的粗皮松萝群体从形态学、生态学、化学及分类学方面进行了初步研究。在分类学上将这一地生群体命名为匍匐变种;在种群落结构方面进行了样方调查;从生物系统学角度进行了初步分析。A terricolous population of Usnea montis-fuji Mot. is found in the alpine cold semi-desert of Changbai mountain of Jilin province in north-eastern China. The population covers a considerably large area from alt. 2080 to 2380m in southern slope of the mountain. The strong prevailing wind trains the prostrate filamentous thalli of Usnea montis-fuji Mot. over the earth from west toward east. The terricolous population is characterized by its disciform or tile-shaped stem base of its filamentous thalli instead of cylindroid one in epiphytic population, and its adventitious rhizines. A preliminary analysis and comparison in biosystematics of the populations from morphology, ecology, chemistry, and taxonomy are carried out.
