广东乳源南水湖国家湿地公园两栖爬行动物多样性调查研究

为掌握广东乳源南水湖国家湿地公园两栖爬行动物多样性现状,2016年3月至2018年10月,采用野外调查和走访调查相结合的方法,在湿地公园选取8条具代表性的样线开展调查研究。调查发现,湿地公园两栖爬行动物共3目21科74种,其中两栖动物1目7科21种,爬行动物2目14科53种;记录国家Ⅰ级重点保护野生动物1种,国家Ⅱ级重点保护野生动物1种;发现湿地公园新记录种34个,其中两栖类12种,爬行类22种。动物区系具有明显的中亚热带区系特点,两栖动物以华中—华南区共有种及东洋界广布种占优势,爬行类以东洋界为主体。当前湿地公园的两栖爬行动物仍面临一定盗猎压力及栖息地遭破坏威胁。基于专项调查数据,针对湿地公园两栖爬行动物多样性及其保护提出加强自然栖息地保护及被破坏生境的恢复工作等保护管理建议。

Diversity of Amphibians and Reptiles in Ruyuan Nanshuihu National Wetland Park of Guangdong

8 representative transects were selected from March 2016 to October 2018 to research the diversity of amphibians and reptiles in Ruyuan Nanshuihu National Wetland Park of Guangdong based on field investigation and interview.74 species of amphibians and reptiles in 21 families of 3 orders were found in the park,including 21 species of amphibians in 7 families of 1 order and 53 species of reptiles in 14 families of 2 orders,as well as 1 species of level I key state-protected wildlife and 1 species of level II key state-protected wildlife.34 new species were recorded including 12 species of amphibians and 22 species of reptiles.The fauna of amphibians was dominated by the common species of Central China—South China distribution and the widespread species of the Oriental realm,while the fauna of reptiles was dominated by the Oriental realm.The amphibians and reptiles in the park were still threatened by hunting pressure and habitat destruction at present.Based on the special investigation data,the paper suggested to strengthen the protection of natural habitat and the restoration of damaged habitat for the diversity of amphibians and reptiles in the wetland park.
