秦岭国家植物园陆栖脊椎动物多样性及区系分析

Species Diversity and Fauna of Terrestrial Vertebrates in Qinling National Botanical Garden

  • 摘要: 【目的】了解秦岭国家植物园陆栖脊椎动物资源现状,更好地掌握和保护该区域物种资源和生物多样性。【方法】通过对2019—2022年的野外调查并结合已有监测数据和文献记载,对该区域陆栖脊椎动物名录进行整理、更新及分析,包括分类、保护级别、濒危等级、区系及分布型等。【结果】研究结果表明,秦岭国家植物园分布有陆栖脊椎动物4纲29目99科208属306种,其中,两栖纲2目7科11属11种、爬行纲2目9科15属18种、鸟纲18目60科143属234种、哺乳纲7目23科39属43种,较《秦岭植物园科学考察报告》所记录的142种新增了164种。国家级和省级重点保护野生动物69种,中国特有种31种,受威胁物种25种。在动物地理区划上,以东洋界物种占优势(45.42%),兼有古北界物种(31.70%)和广布种(22.87%);从分布型来看,分属13个分布型,其中以东洋型、古北型、喜马拉雅—横断山区型的物种占明显优势,同时其他分布型也占有一定比例。通过对各类群进行G-F指数分析可知,鸟类的G指数、F指数和G-F均最高,哺乳类次之,两栖类最低。【结论】秦岭国家植物园处于东洋古北两界物种的交融汇集区,具有较高的陆栖脊椎动物丰富度,重点保护及特有物种较多;同时物种数呈明显增长趋势,说明物种多样性存在被低估的可能;在科、属多样性水平上,鸟类相对丰富,哺乳类次之,两栖类最低。因此,建议进一步增大调查范围和频次,采用多种技术开展物种本底调查。

     

    Abstract: 【Objectives】 To understand the status quo of terrestrial vertebrate resources in Qinling National Botanical Garden and to get better acknowledgment and protection of the species resources and biodiversity in this area. 【Methods】 Based on the field investigation during 2019-2022 and combined with the existing monitoring data and literature records. The list of terrestrial vertebrates in the region was collected, updated, and analyzed, including classifications, protection levels, endangered levels, fauna and distribution types. 【Results】 The results showed that there are 4 classes, 29 orders, 99 families, 208 genera, and 306 species of terrestrial vertebrates, including 2 orders, 7 families, 11 genera, 11 species in amphibia; 2 orders, 9 families, 15 genera, 18 species in reptilia; 18 orders, 60 families, 143 genera, 234 species in ave; 7 orders, 23 families, 39 genera, 43 species in mammalia. Compared with the 142 species recorded in the Scientific Investigation Report of Qinling Botanical Garden, 164 species were added. Among these, 31 species were endemic to China, 69 species were listed as national and provincial class key protected wildlife, and 25 species were threatened species. In terms of zoogeographical division, the Oriental species dominated (45.42%) with the existence of Palaearctic species (31.70%) and widespread species (22.87%). From the perspective of distribution types, the animals belonged to 13 distribution types, among which the Oriental pattern, Palaearctic pattern, Himalayan-Hengduan Mountain pattern species were dominant, and other distribution patterns also occupied a certain proportion. By analyzing the G-F index of each class, we found that the G index, F index, and G-F index of birds were the highest, followed by mammals and amphibians. 【Conclusions】 Qinling National Botanical Garden was located in the confluence area of Oriental and Palaearctic species. It had high terrestrial vertebrate richness and many key protected and endemic species. The number of species showed a significant growth trend, indicating that there was a possibility of underestimation of species diversity. At the level of family and genus diversity, birds were relatively abundant, mammals were second, and amphibians were lower. Therefore, it could be suggested to further increase the scope and frequency of investigation and use a variety of techniques to carry out the species background investigation.
