摘　　要：为探讨采伐活动对丰林自然保护区森林地表蜘蛛的影响,于2018年6月28日至7月18日分别对阔叶红松林采伐前和采伐中进行取样调查.结果表明:(1)整个取样过程共采集蜘蛛975头,分属36物种,其中采伐前捕获635头,采伐中共捕获340头.(2)在该试验中,采伐前优势种有2种,占总数的45.75%,采伐中优势种有3种,占总数的70.88%,分别是采伐前和采伐中地表蜘蛛的主要组成部分.(3)采伐前与采伐中蜘蛛个体数量的差异性极显著(P<0.01),物种数虽差异性不显著但数量上有一定变化.采伐前蜘蛛群落多样性指数均大于采伐中的蜘蛛群落多样性指数,说明采伐活动对阔叶红松林中的游猎型蜘蛛群落有一定影响.To investigate the impact of logging activities on the forest floor spider Fenglin Nature Reserve, were sampled survey of former broadleaved Korean pine logging and harvesting on June 28 th 2018 to July 18 th. The results showed that:(1) A total of 975 spiders were collected during the entire sampling process, belonging to 36 species, of which 635 were captured before logging and 340 were captured during logging.(2) In this experiment, there are two dominant species before harvesting, accounting for 45.75% of the total, and three dominant species during harvesting, accounting for 70.88% of the total. They are the main components of surface spiders before harvesting and during harvesting.(3) Before harvesting and harvesting individual differences in the number of spiders significantly(P<0.01), but there are some changes in the number of species, although the number of the difference was not significant. Before harvesting the spider community diversity indexes of all logging in the spider community diversity index, indicating that logging activities have an impact on broadleaved Korean pine forest of wandering spiders community.
