摘要:
为了探索抚育经营对森林群落多样性指数及蓄积量的影响，采用典型样地取样法，把位于同一地点的杉木马尾松群落分成2部分，一部分进行中度抚育，另一部分不抚育，10 a后对2部分乔木树种的多样性指数及蓄积量进行研究。结果显示，未进行抚育的群落内乔木层物种多样性Shannon-Wiener指数（H’）为2.029 0，Simpson指数（D）为0.853 7，Pielou均匀度指数（J）为0.881 2，总蓄积量为30.627 4 m3；抚育后的群落内乔木层物种多样性H’为2.190 0， D为0.851 8，J为0.790 0，总蓄积量为54.213 1 m3。抚育后群落的多样性指数H’明显提高，Simpson指数D大致相等，Pielou均匀度指数（J）有所下降，森林总蓄积量显著提高。说明适当的森林抚育措施可以提高群落的生物多样性和蓄积量。
Abstract:
This article dealt with the effects of tending management on forest community diversity index and volume. The community composed of Cunninghamia lanceolata and Pinus massoniana （Lamb.）in the studied area was divided into two parts by typical plot sampling. One part was moderately tending, the other remained unchanged. After 10 years, the diversity index and volume of tree species in the two parts were analyzed. The species diversity indexes of tree layer in the community without tending were shown as followed, Shannon Wiener index (H’) was 2.029 0, Simpson index (D) was 0.853 7, Pielou evenness index (J) was 0.881 2, and the total volume was 30.627 4 m3.The species diversity indexes of tree layer in the community after tending, shown as H’ was 2.190 0, D was 0.851 8, J was 0.790 0, and the total volume was 54.213 1 m3. After tending management, H’ of the community increased, D was approximately equal, J decreased, and the total forest volume increased significantly. It was concluded that appropriate forest tending measures could improve the biodiversity and volume of the community.
