摘要
在云南省大理市苍山火烧迹地采用陷阱法初步研究了火干扰对苍山云南松林步甲群落的影响。其中未火烧迹地步甲群落由7属14种组成;火烧迹地步甲群落由6属8种组成,样地间多度没有显著差异。未火烧迹地步甲群落物种组成不同于火烧迹地,但部分火烧迹地与未火烧迹地接近;健步甲Carabussolidior是森林生境良好的指示物种(IndVal=0.9489,P=0.001)。研究显示,火干扰已经改变了云南松林步甲群落组成,降低了步甲群落的多样性。
The impact of forest fire disturbance on carabid beetles in the forests of Pinus yunnanensis was studied by means of plot sampling investigation on the burned sites and the control plots in Cangshan of Yunnan. Fourteen carabid species of seven genera were captured in non-burned plot; eight species of six genera were captured in burned plot. No significant difference was found in abundance among these plots. Species composition of the non-burned plot was different from that of the burned plot, while some burned plots were similar to the non-burned plots. Carabus solidior was indicator species for the forest （IndVal=0.9489, P=0.001）. As a result, we conclude that the species composition of Pinus yunnanensis in Cangshan on carabid beetles had changed by the fire, which also reduced the diversity of carabid beetles.
