2016年8月通过对云南景迈布朗族古茶园进行调查,分析了古茶园生态系统的物种组成、径级水平结构和垂直结构,为深入了解古茶园生态系统的多样性维持机制和科学评价古茶园的植被状况提供参考。结果表明:群落中共有植物39种,全都为被子植物,隶属20科33属,未发现裸子植物;物种多样性丰富,区系地理成分热带性质明显。群落更新稳定,茶树在荫蔽条件下完成了自我更新,数量上占绝对优势。群落垂直空间分层明显,乔木层平均胸径为24.29 cm,崖摩胸径最大,为24.39 cm;主要优势树种为西南木荷、云南栘和蒲桃,高度差异极显著,分为乔木层与灌木及乔木更新层2个大层,每个大层中又可细分为上下2个亚层;乔木层个体数量少,但对下层植物有较大影响。
In August 2016, the investigation was conducted on the ancient tea gardens of Jingmai Brang in Yunnan Province to analyze the species composition, the horizontal structure and the vertical structure of the ancient tea garden ecosystem. In order to understand the mechanism of maintaining the diversity of the ancient tea plantation ecosystems and to evaluate the ancient Tea plantations provide a reference. The results showed that there were 39 species of plants in the community, all of them were angiosperms, belonging to 33 genera of 20 families. No gymnosperms were found. The species diversity was rich and the tropic features of flora were obvious. Community renewal and stability, tea shade in the shade completed a self-renewal, the number of absolute advantage. The vertical space of the community was obviously stratified. The average DBH of arborous layer was 24.29 cm and the diameter of Cliff was the highest, which was 24.39 cm. The main dominant tree species were Hemiphylla sapratum, Tree renewal layer 2 large layers, each layer can be subdivided into two sub-layers; upper and lower arbor layer number of individuals, but have a greater impact on the lower plants.
