中文摘要：

根据野外调查的样地资料，本文分析了分布于河南省伏牛山、熊耳山、太行山等林区的连翘群落的种类组成、群落外貌、结构特征及物种多样性等基本生物学特征。结果表明：群落共有维管植物52科105属127种，其中优势科为木犀科、蔷薇科、蝶形花科、壳斗科、菊科及毛莨科等；该群落是以连翘为主的单优种群落，生活型以高位芽植物占优，草本植物中地面芽占优势，群落季节相分明；垂直分化明显，一般分为乔木层、灌木层、草本层3层；草本层和灌木层植物种类较乔木层丰富，对连翘群落物种多样性具有较大影响，物种多样性的大小顺序依次为草本层〉灌木层〉乔木层。

英文摘要：

According to the data of field plots, the preliminary characteristics such as the floristic composition, community structure and species diversity of Forsythia suspensa （Thunb.） Vahl were analyzed in Funiu Mountain, Xionger Mountain and Taihang Mountain in Henan. The results show that 127 species were found which belonging to 105 genera 52 families, in which the dominant families are Oleaceae, Rosaceae, Fabaceae, Fagaceae, Asteraceae, Ranunculaceae. Phanerophytes are the largest in number of all species in the community according to Raunkiaer＇ s statistics of life form. Hemicryptophytes are advantage part of herbaceous plants. The aspection of the forest community is distinct all the year round. The vertical structure is obvious and can be commonly divided into three layer： arborous stratum, shrub stratum and herbaceous stratum. The shrub stratum and the herbaceous stratum are relatively abundant in species and have a greater effect on the community diversity. The species diversity index rank from high to low was： herb layer 〉 shrub layer 〉 arbor layer.
