基于监测网格对广东中山香山省级自然保护区陆生脊椎动物的编目调查

Terrestrial Vertebrate Survey Based on Monitoring Grid System in Zhongshan Xiangshan Nature Reserve,Guangdong Province

2018年1月至2020年10月,在广东中山香山省级自然保护区划分16个2km×2km的监测网格,每网格内布设1条监测样线及1台红外相机,开展陆生脊椎动物编目调查。样线调查重复8次,红外相机累计工作日14012d,记录独立有效拍摄384次。共记录陆生脊椎动物22目62科168种,其中两栖类1目5科16种、爬行类2目14科36种、鸟类14目36科106种、兽类5目7科10种。有国家Ⅰ级重点保护物种2种、国家Ⅱ级重点保护物种21种、广东省重点保护物种13种。红外相机记录兽类中,相对多度较高物种为小灵猫(RAI=1.877)和果子狸(RAI=0.271)。该研究首次对广东中山香山省级自然保护区开展系统的陆生脊椎动物编目调查,为保护区乃至中山市的野生动物保护管理提供重要的本底资料和科学依据。

From January 2018 to October 2020,we conducted terrestrial vertebrate survey in Zhongshan Xiangshan Nature Reserve,Guangdong Province, based on 2×2 km monitoring grid system. We divided the nature reserve into 16 monitoring grids, set up 1 line transect and 1 camera trap in each grid. We repeated the line transect survey 8 times through the 3-year survey, with a survey effort of 14,012 camera-days,we obtained 384 independent detections. The survey recorded a total of 168 species belonging to 62 families and22 orders,including 16 amphibian species belonging to 5 families and 1 order,36 reptile species belonging to 14 families and 2 orders,106 avian species belonging to 36 families and 14 orders,and 10 mammal species belonging to 7 families and 5 orders. We recorded 1 species of first-class National Protected Wildlife,15 species of second-class National Protected Wildlife,11 species of Guangdong Provincial Protected Wildlife. Among the mammal species recorded by camera traps,the relative abundance index(RAI)was used to assess the regional species abundance. The 2 most abundant mammal species with a higher RAIs in the Xiangshan Nature Reserve were Viverricula indica(RAI=1.877)and Paguma larvata(RAI=0.271).This study was the first systematic survey on terrestrial vertebrate in Xiangshan Nature Reserve,Guangdong Province,which could provide a background information and scientific basis for wildlife conservation and management in Xiangshan Nature Reserve and Zhongshan city.
