通过永久样地调查编目和生物量预测模型估算了鼎湖山季风常绿阔叶林锥栗＋黄果厚壳桂＋荷木群落植物现存量。结果表明：（１）群落植被生物总量为２９５．６４０ｔ／ｈｍ２，其中乔木层为２８６．０６１ｔ／ｈｍ２、灌木层８．９００ｔ／ｈｍ２、草本层０．３３０ｔ／ｈｍ２、层间植物０．３４９ｔ／ｈｍ２，分别占植被总生物量的９６．７６％、３．０１％、０．１１％和０．１２％。（２）乔木层生物总量中，树干、枝、叶和根生物量依次为１４９．４８８、７８．９４０、５．８６７和５１．７６６ｔ／ｈｍ２。（３）垂直分配结构表明生物量随林分高度级的增加而增加。Ｈ≤５ｍ、５＜Ｈ≤１０ｍ、１０＜Ｈ≤２０ｍ和Ｈ＞２０ｍ树干生物量百分比分别为２．３６％、８．４５％、３１．６８％和５７．５１％，生物量密度各为２．１１５、３．６２６、６．２８３和７．０６８ｔ／ｈｍ２．ｍ。（４）生物量排在前１０位的树种依次为锥栗（Ｃａｓｔａｎｏｐｓｉｓｃｈｉｎｅｎｓｉｓ）、黄果厚壳桂（Ｃｒｙｐｔｏｃａｒｙａｃｏｎｃｉｎｎａ）、荷木（Ｓｃｈｉｍａｓｕｐｅｒｂａ）、观光木（Ｔｓｏｏｎｇｉｏｄｅｎｄｒｏｎｏｄｏｒｕｍ）、肖蒲桃（Ａｃｍｅｎａａｃｕｍｉｎａｔｉｓｍａ）、厚壳桂（Ｃｒｙ?
Based on the permanent sample inventory and biomass prediction model, the present plant biomass of Castanopsis kawakamii + Betula platyphylla + Schima superba in Dinghu Mountain monsoon evergreen broad-leaved forest was estimated. The results showed that: (1) The total biomass of community vegetation was 295.640 t / hm2, including 286.061 t / hm2 for arbor layer, 8.900 t / hm2 for shrub layer, 0.330 t / hm2 for herb layer and 0.349 t / Hm2, accounting for 96.76%, 3.01%, 0.11% and 0.12% of the total vegetation biomass, respectively. (2) The biomass of tree layer, trunk, branch, leaf and root biomass were 149.488,78.940,5.867 and 51.766t / hm2, respectively. (3) The vertical distribution structure showed that the biomass increased with the increase of forest height. The biomass of trunk biomass of H≤5m, 5 20m were 2.36%, 8.45%, 31.68% and 57.51% 2.115, 3.626, 6.283 and 7.068 t / hm2. m. (4) The top ten species of biomass were Castanopsis chinensis, Cryptocaryaconcinna, Schimasuperba, Tsoongiodendronodorum, Acmenaacum inatisma, Cry?
