摘　　要：景天科瓦松属植物具有较高的药用价值,现代药理研究表明,该植物具有抗癌、抗炎、抗菌、强心、抗病毒和免疫调节等作用。为了更好地保护和利用长白山区野生瓦松属植物的野生资源,该研究以本地区狼爪瓦松、黄花瓦松和钝叶瓦松3种瓦松属植物为材料,研究其野生种群的分布和生态特征。结果表明:该地区的3种瓦松属野生种群所属的群落分别为地椒百里香-狼爪瓦松群落、地椒百里香群落、狼爪瓦松群落、黄花瓦松群落和钝叶瓦松群落。因瓦松属植物野生栖息地大多为石砬子山,其伴生种多为耐旱耐贫瘠的岩生植物,群落植物多样性较单一,因此各群落之间类似度较高。The plants of Orostachys have high medicinal value.Modern pharmacological studies have indicated that this species has anti-cancer,anti-inflammatory,antibacterial,cardiotonic,antiviral,and immunoregulatory effects.To protect and utilize wild resources of Orostachys in Changbai Mountain area,this study used three Orostachys species,i.e.,O.cartilaginea A.Ber.,O.spinosa(L.)Sweet,and O.malacophylla(Pall.)Fisch to investigate the distribution and ecological characteristics of Orostachys species.The results showed that the wild populations of the three Orostachys species separately belong to the communities of Thymus mongolicus-O.cartilaginea,O.cartilaginea,Th.mongolicus,O.spinosa,and O.malacophylla.Most of wild Orostachys plants habited in rock mountain,which their companion species were mostly the drought-and infertile-tolerant rock plants.Furthermore,the plant community diversity was relatively simple,thus showing a high similarity among the communities.
