    摘要:

    选取5个物种多样性指数, 对浙江省40个养护期内的废弃采石矿区的物种多样性进行了研究, 结果表明, (1)浙江废弃采石矿区内植物种类较多, 科属组成较为分散。从群落结构组成来看, 草本植物为优势群体, 草本植物引导种以豆科类植物和禾本科类植物居多。(2)草本、灌木和乔木植物群落丰富度指数和物种多样性指数都表现出一致的变化趋势, 草本植物群落的这些指数值明显高于灌木和乔木植物群落, 草本、灌木和乔木植物群落的群落均匀度指数都较高。(3)浙江省废弃采石矿区内草本植物乡土物种占主导地位, 其中以菊科类植物居多。

    Abstract:

    Five species diversity indices were chosen to carry out species diversity analysis of deserted quarry areas during the maintenance period after artificial vegetation restoration in Zhejiang Province. Results showed that the quantity of species in the areas was large, while the composition of families and genera was unintensive. To be exact, herbs acted as the dominant group in the community selecting leguminious plants and gramineae plants as the two biggest communities for the introduced species. Shrubs and trees were mainly planted rather than growing from seeds. The index of species richness and species diversity of herbs, shrubs, and trees showed a consistent trend, among which the index value of herb communities was significantly higher than the index values of the shrub and tree communities. In addition, the community evenness index values of herb, shrub, and tree communities all stayed in a high level. Local herbs in the areas played a dominant role and the majority was compositae plants.
