封禁措施对云南金沙江流域主要林分的生态功能影响

Shuitu Baochi Xuebao, 2007
通过封禁措施对林分的生态功能影响分析,认为：封禁后的云南松林和常绿阔叶林,在胸径或树高上都表现出明显的优势,且乔木上层盖度较大而均匀,优势种优势度明显,各优势种种群的年龄组成亦处于稳定状态,乔木树种多数更新良好,在垂直分布上呈连续分布,使整个群落在结构上处于稳定的状态;实施封禁措施的林分物种丰富度和多样性指数都明显高于未封禁的林分,且封禁时间越长,多样性指数越高。封禁后物种多样性指数总体上表现为常绿阔叶林〉针阔混交林〉针叶林〉灌丛;实施封禁措施,土壤得到改良,通透性能较好,封禁后的腐殖质层厚度 ...
