人为干扰对巨桉人工林林下植物多样性和土壤理化性质的影响

Effect of human disturbance on species diversity and soil physicochemical properties of Eucalyptus robusta plantation

  • 摘要: 研究不同强度人为干扰(L:轻度干扰、M:中度干扰和H:重度干扰)对四川雅安苍坪山公园桉树人工林物种多样性和土壤理化性质的影响。结果表明:共记录维管植物75种,隶属52科71属;灌草层物种多样性指数均无显著差异性(P>0.05);随着干扰强度的增强,灌木层物种多样性指数呈现先增加后减小的趋势,草本层物种多样性指数呈现先减小后增加趋势,全氮、速效磷、有机质、速效钾和全钾含量均呈现出减小的趋势;pH值、全氮、全磷、速效钾和全钾含量与草本层物种多样性密切相关;灌木层多样性指数与含水量呈显著负相关。

     

    Abstract: Anthropogenic interference of different intensities (L:mild interference、M:moderate interference&H:severe disturbance)on species diversity and soil physical and chemical properties of Eucalyptus robusta plantation in Cangping Mountain Park, Ya'an, Sichuan. The results showed that a total of 75 species of vascular plants belonging to 71 genera in 52 families were recorded. There was no significant difference in the species diversity index of shrub layer (P>0.05). With the increase of disturbance intensity, the species diversity index of shrub layer showed a trend of first increasing and then decreasing, and the species diversity index of herbaceous layer showed a trend of first decreasing and then increasing, the contents of total nitrogen, available phosphorus, organic matter, available potassium and total potassium all showed a decreasing trend. The contents of pH values, total nitrogen, total phosphorus, available potassium and total potassium were closely related to the species diversity of the herbaceous layer. The shrub layer diversity index was significantly negatively correlated with water content.
