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 2 2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 Shan-non- wiener均匀度指数藤本层的最大 ,草本层的最小。
This paper studied the plant species diversity of Pinus massoniana plantation restored by the control measures of interplanting of trees and grasses in Bashilihe River Basin, Htian Town, Changting County, Fujian Province. The results showed that the species of undergrowth increased after severe soil erosion, soil preparation, fertilization and mixed with Lespedeza heterophylla and other measures. The species of undergrowth increased, accounting for 22 species, 30 genera and 33 species. The geographical composition of the community is dominated by tropical components, with the largest number of evergreen shrubs in lifestyles, few in perennials and annuals, and high-budded plants dominate the community. In the community shrubs, Lespedeza, Huangruimu, Cunninghamia lanceolata, Camellia oleifera and Thunbergii were the most important species, while the herbaceous species was dominated by Megalobrama amblycephala. The Shannon-wiener and other diversity indices were the highest in the shrub layer, the herb layer, The smallest, while the Shan-non wiener evenness index is the largest in the vine layer, the smallest in the herb layer.
