【摘要】 采用常规野外调查法,对金佛山自然保护区南、北、西三个坡不同海拔梯度的植物优势种进行了调查研究。结果表明:1)金佛山自然保护区各坡在海拔1840m处乔木层的优势种都是常绿阔叶林木,其中北坡1840m和西坡1840m的乔木优势种为簇叶新木姜子(Neolitsea confertifolia(Hemsl.)Merr.),南坡1840m的乔木优势种为水青冈(F.longipetiolata Seem.)。其他海拔乔木层的优势种未呈现规律性。西坡各个海拔乔木层的优势种都属于常绿阔叶林木,而其他坡未呈现规律性。2)北坡840m和西坡840m的灌木层优势种都为乔木幼树,分别是四川大头茶幼树(Gordoniaacuminata Chang)和油茶幼树(Camellia oleifera Abel)。3)各坡海拔1840m处,植被覆盖率高,郁闭度大,草本层以阴生的植物为优势种。更多还原

【Abstract】 Dominant plant species were investigated at different altitudes in the Jinfo Mountain Nature Reserve.The results showed that:1) the dominant plant species of arbor layer at 1840m level of each slope belonged to the same type which was evergreen broad-leaved forest.The dominant plant species of arbor layer at 1840m level of north slope and west slope were Neolitsea confertifolia(Hemsl.) Merr,while F.longipetiolata Seem was the dominant plants at south slope.However,the dominant plant species of arbor layer at other altitude were of different vegetation type. The dominant plant species at each altitude of west slope were species of evergreen broad-leaved forest. 2) The dominant plant species of shrub layer at 840m of north and west slope were saplings of Gordonia acuminata Chang & Camellia oleifera Abel.3) The coverage of plants was high at 1840m of each slope,and the dominant plant species were shade plants as well.更多还原
