【Abstract】 In the present paper 8I species and subspecies of amphibia and reptiles including the historical records of Gansu Province, China have been given. They belong to 5 orders,I6 families and 4I genena. Among them 4 species are the new records in Gansu province.From the preliminary analysis of amphibia of our material,thereare I5 species and subspecies appertaining to Oriental realm, making up 62.50% of the total; 4 species and subspecies are found to be 16.67% of the total, belonging to Paleartic realm; other 5 speice and subspecies making up about 20.83% are of the two realms mentioned above.As to the reptiles, 27 species and subspecies belong to Oriental realm, making up 47.37% of the total; 25 species and subspecies are found to be 43.85% of the total, appertaining to Paleartic realm. Only 5 species and subspecies making up about 8.77% are of the two realms mentioned above. Obviously, the Oriental realm elements are predominating in both amphibia and reptiles.According to the record of fauna elements analysis, we regard Qinling mountains as a zoogeography demarcation line between Oriental realm and paleartic realm.Based on the results of stomach-contents examination of 18 amphibia and 22 species of reptiles, it has been shown that about 100 per cent are the common insectivorous or carnivorous forms, such as Bufo and Rana, which are dominant, the benifical coefficient usully arrives in 50 -97.8% per cent. All of snakes especially like to eat up rodents. Therefore they are benificial to crops, forests and herbages, and they should be put under protection. But snakes as mentioned above belonging to the genera of Agkistroden and Trimresurus are venomous snakes, which are harmful to mankind and domestic animals, ann should be controlled.更多还原
