| 生物多样性资源本底调查是加强生物多样性科学保护和管理的重要基础,可为制定科学的保
护措施和管理策略提供支撑。2022 年6 月上旬和8 月中下旬,采用样线法和走访调查法,对澧县县域两栖爬行动物资源进行了调查。结果表明,样线调查共发现两栖动物2 目8 科 23 种,爬行动
物2 目10 科26 种;采用eDNA宏条形码技术共检测出两栖动物16 种、爬行动物1 种,其中5 种为样线法未调查到的物种。 动物区系组成以东洋界物种(26 种)为主,其次为广布种(23 种),无古北
界物种分布,其中虎纹蛙、乌龟和宽脊疣螈为国家二级重点保护野生动物;33 种为湖南省地方重点保护野生动物;29 种为具有重要生态、科学、社会价值的陆生野生动物;分别有4 种、10 种、7 种被《中国生物多样性红色名录》列为濒危(EN)、易危(VU)、近危(NT)等级物种。 |
| 英文摘要: |
| The background survey of biodiversity resources is an important foundation for strengthening
the scientific protection and management of biodiversity, and provides an effective basis for formulating
effective protection measures and management strategies. In early June and mid to late August 2022, the
amphibians and reptile resources in Lixian County were surveyed using the sample line method and the
visit survey method. This survey recorded 23 species of amphibians from 2 orders and 8 families, and 26
species of reptiles from 2 orders and 10 families. A total of 16 amphibian and 1 reptile species were detected using the environmental DNA (eDNA) meta barcoding technique, five of which were species not
surveyed by the sample line method. The composition of the fauna was dominated by 26 Oriental species,
followed by 23 widespread species, with no Palaearctic species recorded. Among them, Hoplobatrachus
chinensis, Mauremys reevesii and Tylototriton broadoridgus were listed as national second-class key protected wild animals; 33 species were listed as Hunan provincial key protected wild animals; 29 species
were terrestrial wild animals recognized for having important ecological, scientific and social value; 4,
10, and 7 species were respectively categorized as endangered ( EN), vulnerable ( VU), and near
threatened (NT) in the China Biodiversity Red List. |
