| 摘 要： | 为了深入认识二代野猪放牧对夹金山针阔混交林物种多样性特征和土壤理化性质的影响,以便为该区域针阔混交林的生态稳定性维持以及科学放牧提供参考,该研究在全面踏查的基础上,根据牧道数量、面积、野猪行为特征及活动范围划分4种放牧干扰强度(由强到弱依次为I、II、III、IV),并设置无干扰状态作为对照(CK),探讨不同放牧干扰强度对物种多样性和土壤理化性质的影响以及二者之间的作用关系。主要结果:(1)共记录到维管植物172种,隶属于55科117属,轻度干扰(IV)下乔灌草的科、属、种数目均达到最高。(2)乔灌草3层多样性指数对干扰强度的响应基本一致,IV级干扰下丰富度指数(S)、Shannon多样性指数(H′)和Simpson优势度指数(D)达到最大,高于CK,随干扰增强多样性水平均趋下降;各干扰强度间Pielou均匀度指数(E)差异不显著。(3)相比于CK,野猪放牧致使土壤含水量、最大含水量、全氮含量下降,放牧压力越大,下降比例越大;土壤孔隙度、全磷、速效磷、有机质含量在IV级干扰时有所增加, I–III级干扰下明显削减;土壤密度随干扰增强而增大。(4)冗余分析结果表明:土壤有机质含量、速效磷... |
