| 摘 要： | 采用目前测定物种多样性的几种方法，对马尾松、木荷、苦槠等针阔树混交林的乔木层物种多样性进行了测定和分析．结果表明，该混交林乔木层的物种多样性指数分别为３．３８６６，３．３４２７，０．５５９３，０．５１８７，０．６３４３和４７．９３８７％，均低于南亚热带常绿阔叶林和同一气候带的石灰岩常绿落叶混交林．对测定数据中均匀度（Ｅ）与种在个体数量上的变动系数（Ｃ）进行拟合，结果为：Ｅ＝－２．２０＋（５０．２０／Ｃ），ｒ＝０．９９７１．

| Abstract: | The species diversity of the tree stratum in the mixed forest of Pinus massoniana,Schima superba,Quercus myrisinaefolia,etc.has been determined and analysed with several present methods of determining species diversity.The results show that the species diversity indexes of the tree stratum of the mixed forest are respectively 3.3866 (with Simpson's method),3.3427(Whittaker's),0.5503(Shannon-weiner's) 0.5180(Brillouin's),and 0.6343(PIE);and the evenness is 47.9387%.These indexes are all lower than those of the evergreen broad leaved forest in the South-Asian tropics and those of the evergreen deciduous mixed forest in the same climatic belt. Fitting the evenness (E) of the determimed data to the variable coefficient of the Species in individual quantity,the results are as follows:E=-2.20 (50. 20/C),r=0.9971 |
