中文摘要:

宁夏地区已记录的甲虫种数超过1000种（亚种），是构成该地区昆虫多样性的主要成分。本文对宁夏六盘山、贺兰山和罗山3个国家自然保护区已知甲虫种类的数量做了分析比较，得到以下不同的研究结果：六盘山、贺兰山和罗山分别有甲虫35科243属482种（亚种）、30科211属355种（亚种）、30科182属287种（亚种）；从动物地理区系看，3区甲虫的广布型种类所占比例很高，分别占总种数的88.17%、85.91%和86.41%，尤以古北型+中国-日本型为突出。3区仅在古北界分布的类型所占比例较低，分别为11.83%、17.30%和13.59%。3区均无特有属存在，特有种所占比例非常小，分别占总种数的1.87%、0.28%、0.70%；六盘山、贺兰山和罗山甲虫的F指数、G指数和G-F指数依次为：F指数32.9064、29.4920和28.9752，G指数5.1998、5.0281和4.9669，G-F指数0.8420、0.8296和0.8286；贺兰山和罗山甲虫具有的相同种数最多，相似性系数为中等不相似水平，六盘山和罗山，六盘山和贺兰山甲虫的相似性系数均为极不相似水平。

英文摘要:

The beetles of Ningxia have been exceeded 1000 species/subspecies, which were the most important composition of beetles diversity. By analyzing and comparing the beetles of Liupan Mt., Helan Mt. and Luo Mt., different comparing results were obtained. The results showed that, 482 species/subspecies of beetles were recorded in Liupan Mt., belong to 35 families and 243 genera. 355 species/subspecies in Helan Mt., belong to 30 families and 211 genera. 287 species/subspecies in Luo Mt., belong to 30 families and 182 genera. The fauna geographical showed that Liupan Mt., Helan Mt. and Luo Mt. had the most widespread species, which were 88.17%, 85.91% and 86.41%, especially the species of Palearctic realm+Sino-Japanese realm. Palaearctic species only were 11.83%, 17.30% and 13.59% respectively. Peculiar species of three preserves were 1.87%, 0.28%, 0.70% respectively, and there was no peculiar genera exist. Analysis of the beetles diversity by G-F index, the F Indexes of beetles diversities of the Liupan Mt., Helan Mt. and Luo Mt. were 32.9064, 29.4920 and 28.9752. G Indexes were 5.1998, 5.0281 and 4.9669. G-F Indexes were 0.8420, 0.8296 and 0.8286. Helan Mt. and Luo Mt. had most same numbers of species of beetles, and the similarity coefficient was on moderately dissimilar level. The similarity coefficients of Liupan Mt. and Luo Mt., Liupan Mt. and Helan Mt were on extremely dissimilar level.
