| 摘 要： | 目的 探索浙江省天台县大雷山野生夏蜡梅Sinocalycanthus chinensis群落的物种组成、种群结构和种间联结，补充大雷山野生夏蜡梅资源分布情况。 方法 在实地踏查的基础上，结合以往研究资料，选取天台县大雷山夏蜡梅的典型群落，建立5个20 m×20 m样地，进行群落学调查。 结果 ①夏蜡梅所处的群落类型多样，主要有落叶阔叶林、针叶林和竹林，分层明显，乔木层优势种有化香树Platycarya strobilacea、山胡椒Lindera glauca、灯台树Bothrocaryum controversum、杉木Cunninghamia lanceolata、毛竹Phyllostachys edulis；灌木层优势种有中国绣球Hydrangea chinensis、夏蜡梅、悬铃木叶苎麻 Boehmeria tricuspis；草本层优势种有金星蕨Parathelypteris glanduligera、辽宁堇菜Viola rossii、透茎冷水花Pilea pumila。②夏蜡梅的种群结构为“金字塔”型，第Ⅰ级个体比率最高，占56.51%，说明种群正处在增长阶段。③对夏蜡梅群落内的乔木层和灌木层物种对进行种间关联与相关性分析显示，正负关联比均大于1，说明夏蜡梅与大部分树种无相关关系。 结论 大雷山野生夏蜡梅群落中各树种联系紧密，群落的结构和功能趋于完善，但夏蜡梅在群落中可能处于相对独立的地位。鉴于夏蜡梅与红果山胡椒Lindera erythrocarpa、山莓Rubus corchorifolius、浙闽樱桃Cerasus schneideriana、化香树等树种呈负相关关系，具有竞争关系，建议在后期夏蜡梅野外保育过程中，采取适当人为择伐和抚育措施，营造良好的生长环境。图10表5参24

| Abstract: | Objective]This study aims to explore the species composition,population structure and interspecific association of wild Sinocalycanthus chinensis community,and to supplement the distribution of wild S.chinensis resources in Tiantai County,Zhejiang Province.Method]On the basis of field survey and previous research data,five 20 m×20 m sample plots of S.chinensis were established for community investigation.Result](1)The community types of S.chinensis were diverse,mainly including deciduous broad-leaved forest,coniferous forest and bamboo forest,with obvious stratification.The dominant species of tree layer were Platycarya strobilacea,Lindera glauca,Botrocarpyum contoversum,Cunninghamia lanceolata,and Phyllostachys edulis.The dominant species of shrub layer were Hydrangea chinensis,S.chinensis,and Boehmeria tricuspis.The dominant species of herb layer were Parathylyperis glandulgera,Viola rossii,and Pilea pumila.(2)The population structure of S.chinensis was"Pyramid"type,with the highest proportion of individuals in gradeⅠ,accounting for 56.51%,indicating that the population was in the growth stage.(3)The analysis of interspecific association and correlation of species pairs in tree layer and shrub layer showed that the positive and negative correlation ratios were both greater than 1,and there was no correlation between S.chinensis and most tree species.Conclusion]The species of S.chinensis community are closely related,and the structure and function of the community tend to be perfect,but S.chinensis may be relatively independent in the community.In view of its negative correlation and competitive relationship with Lindera erythrocarpa,Rubus corchorifolius,Cerasus schneideriana,Platycarya strobilacea and other tree species,it is suggested that in the later stage of S.chinensis field conservation,appropriate artificial selective cutting and tending measures should be taken to create a good growth environment. |
