摘要 2016年6月,在天台鹅耳枥Carpinustientaiensis原生地浙江省天台县天台山,采用样方法对现存19个野生植株分布区内的植物群落结构特征进行调查,同时分层采集样地内土壤样品,对其理化性质进行检测。结果显示:天台鹅耳枥植株分布区域内土壤理化性质良好,适宜植物生长;样方调查数据表明,天台鹅耳枥生境地群落的物种共有124种,隶属于55科,91属;按照中国种子植物属的分布区类型划分,天台鹅耳枥生境地群落植物属可划分为13个类型;样地中柳杉Cryptomeria fortunei的相对多度、相对频度、相对显著度和重要值均为最高,分别达到40.12%,21.77%,43.51%和35.13%,其生长状况对天台鹅耳枥群落环境影响较大;不同样地的物种多样性存在一定差异,物种数、Simpson优势度指数、Shannon-Wiener多样性指数、Pielou均匀度指数的最大和最小值分别为56(1号)和11(2号),0.943 2(1号)和0.808 9(2号),2.397 9(1号)和1.714 6(3号),0.832 5(2号)和0.426 0(3号)。调查显示,天台鹅耳枥自然分布的植株所处群落环境复杂多样,伴生植物种类和生态类型十分丰富。研究结果将为天台鹅耳枥种群的原地保护、迁地保护以及野外回归等提供重要依据。 Investigations by quadrat sampling were carried out on communities of Carpinus tientaiensis trees in Tiantai of Zhejiang province in June of 2016.And physical and chemical properties of sampled soil were determined.The results showed that physical and chemical properties of tested soil were favorable for plant growth.Investigations on communities demonstrated that there were124 species,belong to 55 families and 91 genera.The areal-types of genera of plant in C.tientaiensis communities could be divided into 13 patterns.The relative abundance,relative frequency,relative prominence and important value of Cryptomeria fortunei in each sample plots were the highest,40.12%,21.77%,43.51% and 35.13%,indicating that the growth of C.fortunei had great effect on the environment of the communities.The maximum and minimum value of species number,Simpson dominance index,Shannon-Wiener diversity index and Pielou eveness index was respectively 56 and 11,0.943 2 and 0.808 9,2.397 9 and 1.714 6,0.832 5 and 0.426.
