摘　　要：本文在考证大量文献资料和定名标本基础上整理出六盘山不全变态类昆虫名录,共计12目70科236属382种。采用二元相似性系数公式SI=C/(A+B-C)对该区昆虫的区系特征及其相互间关系进行了分析。最后以下初步结论:六盘山不全变态类昆虫在世界动物地理区系中,突出古北区成分,共计219种,占已知总数的57.33%,古北界+东洋界混合成分次之,共计122种,占31.94%;在中国动物地理区系中,华北动物区成分113种,占29.58%,其他成分由高到低依次为:蒙新区>东北区>西南区>青藏区>华中区>华南区,表明该区昆虫在区系组成上的特殊性。By means of a large number of literature and named specimens the list of incomplete metamorphosis insects of Liupanshan have been sorted out,including 12 orders,70 families,236 genera,382 species,fauna characteristics of incomplete metamorphosis insects of Liupanshan and interrelation of various insect fauna were analyzed by formulas S I = C /（A ＋B-C）.Finally the conclusion is that ： Incomplete metamorphosis insects fauna of Liupan mountains,Palearctic realm s species（219）accounted for 57.33 % in total, Palearctic reahn and Oriental realm species （ 122 species） accounted for 31.94%, belong to typical Palearctic realm in the zoogeographical area of the world, the proportion of North China （ 113 species） was 29.58 % in Chinese zoogeographical fauna, other composition from high to low as follows： Mongolia Xin area, North East area, South West area, Qinghai-Tibet area , Central China, South China.
