在大兴安岭林区不同采伐区选择典型样地，采用Patrick丰富度指数、Simpson多样性指数、Shannon—Wiener多样性指数及Pielou均匀度指数，研究了不同采伐方式对兴安落叶松林林下物种多样性的影响。结果表明：适度的间伐干扰有利于生物多样性的提高，随着采伐干扰强度和频度的增大，生物多样性会下降；皆伐更新不利于生物多样性的保护，会降低物种多样性指数，改变生物多样性结构；渐伐符合森林更新及林下重要物种对外界环境变化适应的要求，有利于生物多样性和整个生态系统的稳定。

Typical plots were established in Daxing＇ an mountain with different cutting methods using species richness, Simpson diversity index, Shannon-Wiener index and evenness index. Meanwhile, effects of different cutting methods on species diversity for Larix Gmelini forests, the results indicated： Moderate interference can improve biodiversity, With increasing of intention and frequency of cutting; Whatever we consider from renewing of the forest or protecting biological diversity, because it is subversive for biodiversity; once biological diversity is damaged , It is very hard to recover, so we should try our best to reduce the interference and stop clear cutting, which match long benefits of human being.
