淳安县两栖纲野生脊椎动物物种调查编目研究

Research on Investigation and Cataloguing of Amphibians Wild Vertebrate Species in Chun'an County

在淳安县生物多样性最富集的磨心尖、千岛湖、淳安湿地等区域开展野生脊椎动物实地调查的基础上,对该县两栖纲野生脊椎动物调查编目进行了研究。结果表明:淳安县两栖纲野生脊椎动物调查编目,共收录物种31种,隶属于2目9科21属;其中,国家二级保护动物2种,浙江省重点保护动物13种,IUCN红色名录极危(CR)1种,中国脊椎动物红色名录极危(CR)1种、濒危(EN)1种,CITES附录Ⅰ物种1种、附录Ⅱ物种1种;中国特有种18种。分布型以南中国型(S)为主体,有21种,占两栖纲物种总数的67.74%;地理区系以东洋种为优势,有28种,占两栖纲物种总数的90.32%。物种多样性D G指数、D F指数和G-F指数分别为2.91、4.80和0.39,与邻近的福建省5个动物地理省比较,淳安县爬行动物G-F指数高于福建2个动物地理省,低于福建3个动物地理省。

On the basis of the field survey of wild vertebrates in the areas of Moxinjian,Qiandao Lake and Chun'an Wetland,where the most biodiversity is rich in Chun'an County,the investigation catalogue of amphibian wild vertebrates in this county was studied.The results show that the investigation catalogue of amphibian wild vertebrates in Chun'an County contains a total of 31 species,belonging to 2 families and 9 families.Among them,there are 2 species under national secondary protection,13 species under key protection in Zhejiang Province,1 species in the IUCN Red List of Critical Danger(CR),1 species in the Red List of Chinese vertebrates(CR),1 species in Dangered(EN),1 species in Appendix I of CITES,1 species in Appendix II;there are 18 species endemic to China.The distribution type is mainly South China(S),with 21 species,accounting for 67.74%of the total number of amphibian species;the geographical area is dominated by oriental species,with 28 species,accounting for 90.32%of the total amphibian species.The species diversity D G index,D F index and G-F index are 2.91,4.80 and 0.394 respectively.Compared with the five animal geography provinces in neighboring Fujian Province,the reptile G-F index in Chun'an County is higher than the two animal geography provinces in Fujian and lower than the three animal geography provinces in Fujian.
