【摘要】 在鉴定昆虫标本16目157科1979种54795号的基础上,对河北省8个自然保护区(林场)昆虫物种多样性进行了比较.结果表明,各样地的昆虫物种丰富度较高,生态环境和植物群落发育良好,昆虫群落处于较稳定的状态;各样地间的昆虫物种多样性差异较大,以雾灵山的昆虫物种多样性最为丰富;昆虫群落的物种构成与样地间的相互位置关系密切,地理位置越近,物种组成也越相似;昆虫群落的物种多样性受自然环境条件影响和人为活动干扰均较大.更多还原

【Abstract】 The insect species diversity of 8nature reserves(forest farm)in Hebei province were compared.The results showed that,species richness was relatively high,the ecological environment and plant community were well developed,and the insect community was stable in all the 8nature reserves.The insect species diversity were various among different nature reserves,and Wulingshan Mountain had the highest diversity.The species composition of insect communities were closely related to the geodistance.Closer geodistance resulted in more similar the species composition.The species diversity of insect communities were large affected by natural environment and human activities.更多还原
