The Analyses Of The Species Diversity And Faunal Distribution Of Coleoptera In Beijing-Tianjin-Hebei Of China

Based on the determined specimens deposited in the Hebei University Museum, and therelated data from the literatures,1338species of626genera,51families,2suborders ofColeoptera are known from Hebei-Beijing-Tianjin of China. Hereinto, the suborderAdephaga included5families (9.80%),66genera (10.54%),188species (14.05%), and thesuborder Polyphaga included46families (90.20%),560genera (89.46%),1150species(85.95%). Data analyses show that the diversities of Polyphaga in the family, generic andspecific levels are highest, the top10of family category are275species (20.55%) of109genera (17.41%) of Chrysomelidae﹥186species (13.90%) of99genera (15.81%) ofCerambycidae﹥167species (12.48%) of63genera (0.06%) of Scarabaeidae﹥138species(10.31%) of40genera (6.39%) of Carabidae﹥84species (6.28%) of48genera (7.67%) ofCurculionidae﹥65species (4.86%) of30genera (4.79%) of Coccinellidae﹥45species(3.36%) of25genera (3.99%) of Tenebrionidae﹥41species (3.06%) of23genera (3.67%)of Staphylinidae﹥39species (2.91%) of20genera (3.19%) of Dytiscidae﹥32species(2.39%) of12genera (1.92%) of Silphidae.The data indicate that there are5(9.80%) monotypic families,22(43.14%) oligotypicfamilies and24(47.06%) polytypic families in the familial levels;364（58.15%）monotypicgenera,226（36.10%）oligotypic genera and36（5.75%）polytypic genera in the genericlevels. Besides, the result also show that the relation of Beetles quantity and geographicalarea in China:457（73.00%）common genera in the Palaearctic and Oriental Realms，626（100.00%）genera in the Northeast subrealm﹥472（75.40%）genera in the Central Asiansubrealm﹥457（73.00%）genera in the Indo-China subrealm；North China Region（626genera,100.00%）﹥Mongolo-Xinjiang Region（472genera，75.40%）﹥Mid-China Region（457genera,73.00%）﹥North-east Region（357genera,57.03%）﹥Qinghai-XizangRegion（327genera,52.24%）﹥South-west Region（302genera,48.24%）﹥South ChinaRegio（n254genera,40.58%）, these include163（26.04%）endemic genera of North China；The quantity of Beetles in geographical distribution is Plain Area（73.80%）>TaihangMountain Area（65.81%）> Yan Mountains Area（50.80%）>Basins Area（42.33%）> PlateauArea（38.98%）.
