摘要
以银瓶山润楠属植物群落为研究对象,通过典型样地调查,对研究区域内群落的物种组成、径级分布特征进行了研究。结果表明:(1)样地内共有70种植物,隶属41科58属,占优势的科主要有茜草科、樟科、禾本科、紫金牛科、百合科等。(2)样地内重要值>1的物种有11种,占物种数的84.62%,华润楠、浙江润楠的重要值分别为47.08、17.50,远高于其它植物,为调查样地群落的优势建群种。(3)样地内润楠属植物的胸径与树高之间存在显著的对数函数关系,种群径级分布呈单峰型,表现为先升高后降低的趋势,植株最主要集中在中、小径级。
The species composition and diameter distribution characteristics of the communities in the study area were investigated by means of a typical sample plot survey,using the Machilus community in Yinping Mountain as the study object.The results show that:(1) There are 70 species of plants in the sample area,belonging to 41 families and 58 genus,with the dominant families being Cyperaceae,Camphoraceae,Gramineae,Zingiberaceae and Liliaceae.(2) There were 11 species with importance values >1 in the sample site,accounting for 84.62% of the species.The relative abundance,relative significance and importance values of Machilus chinensis and Machilus chekiangensis accounted for 47.08,17.50,respectively,and were the dominant community-building species in the survey sample site.(3) There is a significant logarithmic relationship between the diameter and height of the Machilus in the sample site,and the diameter distribution of the population is unimodal,showing a trend of increasing and then decreasing in diameter,with plants concentrated mainly at the medium and small diameter levels.
