秦岭南坡两栖爬行动物的利用与蛇类食性分析

THE ULTILIZATION OF AMPHIBIA AND REPTILIA AND THE ANALYSIS OF FOOD OF SNAKES IN THE SOUTH FLANK OF TSINGING RANGE

巍巍秦岭,重峦叠嶂,是我国中部一大山系,把陕西省横隔成南北两部分。在动物地理学上作为古北界与东洋界之间的一大屏障,因此研究秦岭的动物区系具有十分重要的意义,曾引起不少学者的关注。David(1875),Sowerby(1912),Pope(1935),胡淑琴等(1966)分别报导了秦岭中段两栖爬行动物调查资料,但秦岭东、西段的南坡迄今未见有报导。我们于1978年5—10月,1979年6—9月,1980年7—10月,先后对秦岭东西段南坡的两栖爬行动物做了调查。

The expedition on amphibia and reptilia during 1978-1980 in the south flank Tsingling Range, attained 425 specimens of amphibia belonging to 11 species (subspecies), 7 generas, 7 families, 2 orders, and 476 specimens of reptilia belonging to 29 species (subspecies), 20 generas, 8 families, 3 orders, and 2 new records of Shanxi Province. Frontal variation of lizard (Eumeces xanthi Guenther) and geographical variation of pit-viper (Agkistrodon halys (Pallas)) were descrided. According to analysis on food habits of 18 species snakes, the result shows that many snakes fed on mice. It is beneficial to the agricultural development. The use and suggestion: 1 . Protecting frogsj 2. Protecting giant salamander;3 . The utilization of black snake,
