黑龙江省蛇类物种多样性调查及保护

Species Diversity Survey and Protection of Snakes in Heilongjiang Province

通过多年的野外调查和采集,共在黑龙江省31个县(市、区)获得蛇类标本592号。结合有关资料记载,证实黑龙江省蛇类隶属2科6属11种,约占我国蛇类总数的5·42%,均属于古北界物种,与国内其他省相比黑龙江省蛇类物种多样性水平较低,种群数量较少。建议加强对蛇类保护生物学的研究及其生境的保护,合理开发利用蛇类资源。

Through several years of field investigation, 592 specimens of snakes have been collected from 31 counties （cities and districts） in Heilongjiang Province. Based on this survey and historical records, there are totally 11 species of snakes belonging to 6 genera, 2 families. They amount to 5.42% of the total number in our country and all of them are Palaearctic species. Comparison with other areas, species diversity level and population number of snakes are lower in Heilongjiang Province. It has been suggested that study on the conservation biology of snakes and protection of the ecological environment should be strengthened, and the snake resources should be utilized reasonable in Heilongiiang Province.
