摘要
采用重要值百分数求顺昌埔上林场次生常绿阔叶林种间竞争系数,以优势种群在正常林分中的优势度作为其容纳量,并用Lotka-Volterra竞争方程讨论调查区次生常绿阔叶林群落的优势种群的竞争.结果表明,平衡时甜锥、丝栗栲、虎皮楠、木荷、酸枣、华杜英、黑锥相对优势度分别为25.7%、17.84%、5.8%、25.32%、7.54%、2.54%、15.25%,据此顺昌埔上次生常绿阔叶林群落将由甜锥、木荷、丝栗栲、黑锥等4个树种共优组成.
In this paper competitive coefficience between the species of secondary evergreen broad-leaf forests in Pusan Tree Farm of Shunchan County are calculated by means of important value of percentage;competition of dominant species in this region is studied as to the dominant degree of normal stands, and by using Lotka-volterra equation, with the results showing that when the stand reaches balance the relative dominant degrees of the species are as follows: Castanopsis eyrei 25. 7%, Castanopsis fargesii 17. 84%, Daphniphyllun glaucescens 5. 8%, Scguna syoerva 25. 32%, Cheerospondias axillaris 7. 54%, Elaeocarpus chinensis 2. 54% and Castanopsis nigrescens 15. 25%.
