2016年,采用样地法对西双版纳热带雨林云南肉豆蔻植物群落乔木层、灌木层、草本层物种多样性和植物群落结构进行调查。结果表明,云南肉豆蔻植物群落内共131个物种,分属于58科104属。其中高位芽植物112种,地上芽植物4种,地面芽植物15种,高位芽植物占总物种85.5%,占绝对优势;云南肉豆蔻植物群落68.71%为中型叶,16.79%为大型叶,小型叶及其它叶级只占14.5%。云南肉豆蔻植物群落物种组成非常丰富,其乔木层、灌木层和草本层Simpson指数(Ds)分别为0.9591、0.9643、0.8781,Shannon-Wiener指数(H’)分别为5.5313、5.2261、4.1060,Pielou均匀度指数(J)分别为2.8446、2.9512、2.4167。群落优势种或建群种为粗叶木(Lasianthus hookeri)、染木树(Saprosma ternate)、望天树(Parashorea chinensis)和云南肉豆蔻(Myristica yunnanensis)等4个树种。
In 2016, the sample plots were used to investigate the species diversity and plant community structure of arbor layer, shrub layer and herb layer in the plant community of the nutmeg in Yunnan’s tropical rainforest. The results showed that there were 131 species in the plant community of Myristica oleracea, belonging to 58 families and 104 genera. Among them, 112 species of high-level bud plants, 4 kinds of ground-bud plants, 15 kinds of ground-bud plants and 85.5% of high-bud plants accounted for the absolute superiority. 68.71% of the plant communities of Yunnan nutmeg were medium-sized leaves and 16.79% Leaves and other leaves only account for 14.5%. The Simpson index (Ds) of tree layer, shrub layer and herb layer were 0.9591,0.9643,0.8781 and Shannon-Wiener index (H ’) were 5.5313, 5.2261 and 4.1060 respectively in Pielou even Degree index (J) were 2.8446, 2.9512, 2.4167 respectively. The dominant species or constructive species are Lasianthus hookeri, Saprosma ternate, Parashorea chinensis and Myristica yunnanensis.
