摘要: 以石门国家森林公园典型南亚热带杉木(Cunninghamia lanceolata)林为对象,对林分内乔木层、灌木层、层间层、草本层的组成及多样性进行调查分析。结果表明,调查区内杉木林乔木层主要树种为杉木、木荷(Schima superba)、马尾松(Pinus massoniana)、罗浮柿(Diospyros morrisiana)、华润楠(Machilus chinensis)、鸭脚木(Schefflera octophylla)等,杉木占比39.7%~68.7%,其他阔叶树占比31.3%~60.3%;林下植物灌木有50种,层间层有21种,草本有19种,具有较高的植物多样性,林下植物总体Shannon-Wiener多样性指数为2.73。该研究为南亚热带杉木林尤其是石门国家森林公园杉木林保育及促进森林植被向更高级阶段演替提供重要依据。

Abstract: The present study aimed to investigate the composition and diversity of arbor, undergrowth, inter and herbaceous layers of the represented south subtropical Cunninghamia lanceolata forest in Shimen National Forest Park. It was found that C. lanceolata accounted for 39.7% to 68.7% of the composition of the arbor layer while other tree species (e.g. Schima superba, Pinus massoniana, Diospyros morrisiana, Machilus chinensis and Schefflera octophylla) occupied about 31.3% to 60.3% of the composition of the arbor layer. There were 50 species of undergrowth plants and shrubs, 21 interlayer species and 19 herbaceous species, evidencing high plant diversity in the forests. The overall Shannon-Wiener diversity index of undergrowth plants was 2.73. The results provide an important basis for the conservation, development and promoting the succession of forest vegetation to a higher stage in south subtropical zone, especially for Shimen National Forest Park.
