摘要:: 在云南哀牢山西麓川河河谷残存有较大面积的季风常绿阔叶林,其周围分布着思茅松林。采用典型取样法,对季风常绿阔叶林及思茅松林的物种组成与群落结构进行了调查和分析,结果表明:季风常绿阔叶林乔木层的优势种主要是红木荷(Schima wallichii)、高山栲(Castanopsis delavayi)、密花树(Rapanea neriifolia),而思茅松成熟林以思茅松(Pinus kesiyavar.langbianensis)为绝对优势。在季风常绿阔叶林的29株样树树干上共调查到附生植物共36种,但在思茅松林中几乎找不到附生植物。季风常绿阔叶林和思茅松成熟林的香农?威纳多样性指数分别为3.32...

Abstract:: There is large area of monsoon evergreen broadleaved forest (MEBF) remained at the lower part of west Ailao Moutain along Chuanhe Valley, with secondary Pinus kesiya var. langbianensis forest (PKLF) scattered around or within it. We employed typical sampling method to analyze and compare the species composition and community structure of MEBF and PKLF in this region. Field survey indicated that Schima wallichii, Castanopsis delavayi and Rapanea neriifolia were the dominant species of tree layer in MEBF, while PKLF was monospeciesformed by Pinus kesiya var. langbianensis. Thirtysix epiphytes were recorded on 29 trunks sampled in MEBF, but seldom was found on trees in PKLF. Shanonon-Wiener index of MEBF and mature PKLF were 3.32 and 1.70, respectively. MEBF showed more complexity in terms of species composition and community structure than PKLF, thus higher stability was expected in MEBF. Unfortunately, there were signs that MEBF had been severely affected by human activities. Thus, it is suggested that the protection of montane primary forests should be strengthened by means of minimizing anthropogenic disturbances, as well as integrating artificial horticulture practices, in the process of a better management of forest resources.
