摘要：

以具北方土石山区典型特征的沂蒙山区为例,在分析土壤侵蚀过程的基础上,选取具生态学意义的侵蚀强度景观格局指数,从垂直维度上分析侵蚀景观格局变化特征。结果表明:土壤侵蚀景观格局具有显著垂直分带性。50～200带为低侵蚀稳定区,人类活动影响大,缀块成片分布,连通性强,形状较规则;400～800带为高侵蚀稳定区,自然因素起主导作用,缀块密度大且分散,形状较复杂;200～400带为侵蚀景观急剧变化区,侵蚀程度随高程增加而增大,自然因素作用增强。微度与轻度侵蚀景观、强烈与极强烈侵蚀景观具相同垂直变化趋势,此两组侵蚀景观变化趋势的差异主要分布于低于300带和高于500带处;中度侵蚀景观变化趋势可视为前两组侵蚀景观变化趋势的过渡。
