    摘要:

    研究了福建省长汀县河田镇八十里河流域采用乔灌混交治理措施恢复的马尾松群落植物多样性研究。结果表明,严重侵蚀地经过整地、施肥、混交胡枝子等措施治理18a后,林下植物种类增加,计有22科30属33种。群落的地理成分以热带成分占优势,生活型以常绿灌木最多,多年生和一年生草本极少,高位芽植物在群落中占据主导地位。群落灌木中以胡枝子、黄瑞木、杉木、油茶和赤楠等树种的重要值较大,草本以芒萁占绝对优势,Shannon-wiener等多样性指数以灌木层最大,草本层次之,藤本层最小,而Shannon-wiener 均匀度指数藤本层的最大,草本层的最小。

    Abstract:

    The understorey plant diversity of artificial recovered Pinus massoniana community by intercropping with shrub species was studied in Hetian town, Changting county, Fujian province. The results showed that the understorey plant species increased 18 years after the seriously eroded land was restored by fertilizer applying and Lespedeza bicolor intercropping, with 22 plant families, 30 genus, and 33 species. The areal types of genus were mostly tropical distribution. The major life form was evergreen shrub, and perennial and annual herbs were few. Phanerophytes took the dominant position. The importance value of Lespedeza bicolor,Adinandra millettii, Cunninghamia lanceolata, Camellia oleifera and Syzygium buxifolium were high in the shrub layer. Dicranopteris dichotoma took the dominant position in the herb layer. Shannon wiener diversity index was highest in the shrub layer, followed by herb layer, and lowest in the vine layer. Shannon wiener uniformity indexes was highest in the vine layer and lowest in the herb layer.
