武夷山自然保护区毛金竹群落特征初步调查

Preliminary Investigation of Phyllostachys nigra var. henonis Community Characteristics in Wuyishan Nature Reserve

以武夷山自然保护区天然分布的毛金竹林分为样地，初步调查了毛金竹林分的群落特征。结果显示：毛金竹群落分布于海拔50～1500m，垂直分布跨度大，生长表现差异明显；海拔、降水和土壤类型是影响毛金竹生长发育的主导因子；毛金竹群落分为乔木层、灌木层和草本层3层，其中灌木层植物种类最为丰富，而乔木层与草本层物种相应较少。

The community characteristics of Phyllostachys nigra var. henonis was investigated on its sample plots naturally distributed at Wuyishan Nature Reserve. The results showed that Ph. nigra var. henonis communities are distributed at the altitude of 50-1,500 m high, with wide span of vertical distribution and tangible difference in growth performance; altitude, rainfall and soil type are the leading factors that affect its growth; its communities are composed of arbor layer, shrub layer and grass layer, while the plant species at shrub layer are most abundant and the species in arbor and grass layers are comparatively lesser in number.
