2015—2022年中国大鲵在浙江省的发现记录及保护现状

On the recorded discovery incidences from 2015 to 2022 and protection status of Chinese giant salamander in Zhejiang Province

中国大鲵(Andrias davidianus)是我国特有的国家二级重点保护野生动物,了解并掌握其种群现状是开展有效保护的前提和基础.然而,由于种群分布及动态等信息的缺乏,限制了其保护与管理工作的发展.系统整理浙江省大规模实施中国大鲵增殖放流后的工作信息,以及2015—2022年浙江省有关中国大鲵发现记录的新闻报道、文献资料等信息,进一步分析中国大鲵发现记录的时空规律.结果表明:浙江省增殖放流点主要集中在衢州、丽水等水资源较丰富,人为因素干扰小的山区;浙江省有关中国大鲵的发现记录有66条,2015—2022年均有中国大鲵的发现记录,发现时间集中在2月及4—7月,这5个月合计记录为45条,占中国大鲵记录总数的68.18%.随着人们保护意识的提高和各个自然保护区的科学保护,有关中国大鲵的发现记录近年来正在不断上升.研究初步调查了报道发现的中国大鲵在浙江省的分布状况及保护现状,为下一步加强大鲵保护管理提供了基础数据.

The Chinese giant salamander(Andrias davidianus)was classified as a unique national secondclass key protected wild animal in China.Understanding and mastering the population status was usually reckoned as the premise and basis for effective protection.However,the lack of information on its population distribution and dynamics limited its protection and management.A systematically organized information was investigated on the proliferation and release of A.davidianus in the history of Zhejiang Province,as well as news reports incidences and literature materials related to the discovery records of Chinese giant salamanders from 2015 to 2022,and then a further analysis of the temporal and spatial patterns of A.davidianus discovery inci-dences records was carried out.The results indicated that the proliferation and release points in Zhejiang Prov-ince were mainly concentrated in mountainous areas such as Quzhou and Lishui,which were rich in water re-sources and had less human interference.There were 66 records of the discovery incidences of A.davidianus in Zhejiang Province.From 2015 to 2022,there were all records of A.davidianus,with the discovery time concentrated in February and April to July.A total of 45 incidences were recorded in these 5 months,account-ing for 68.18%of the total recorded A.davidianusincidences.With the improvement of people′s awareness of conservation and the scientific protection of various nature reserves,the discovery records of A.davidianus were constantly increased.The presented investigation of the distribution and protection status of the A.david-ianus discovered in Zhejiang Province could provide basic data for future in strengthening the management of A.davidianus.
