通过对岳西天峡新发现的银缕梅野生种群的调查,初步摸清了其种群数量与结构、群落特征。银缕梅生存于天峡落叶阔叶林次生林中,乔冠层高度在7～12 m,处于群落发育的盛期,物种丰富,种间竞争激烈,乔木层与灌木层分界不明显。与银缕梅伴生的主要树种有短柄枹、枫香树、黄檀、紫弹朴、青冈、石楠、豹皮樟、台湾泡桐等。银缕梅的分布主要集中在溪谷边和路旁,在阔叶林中分布也是在比较陡峭的坡地上,且呈块状纯林分布,在种间竞争中属弱势种群。根据银缕梅的生长环境和特性,提出了保护建议。

The population, structure and the community characteristic of wild resources of Parrotia subaequalis were shown in Tianxia Mountain of Yuexi, Anhui Province. Based on field investigation, the wild resources of the Parrotia subaequalis were found of 7 -12 meters high in secondary deciduous broadleaved forest on the period of the development of community and had rich species competting strongly with each other, with the boundary of the tree layer and the shrub layer not obvi- ous. Tianxia＇ s Parrotia subaequalis grows with Quercus glandulifera vat brevipetiolata Nakai, Liquidambar formosana Hance, Dalbergia hupeana, Celtis biondii Pamp, Cyclobalanopsis glauca （Thunb.） , Photinia serrulata Lindl, Litsea core- aria var sinensis（Allen） Yang et P. H. Huang Oerst, Paulownia Kawakamii and so on. The main Parrotia subaequals re- source distributes in the valley edge or by the roadside. They distribute with a group on steep slope, and are vulnerable populations competting with other species.
