| 为理解旅游道路交通导致的两栖类致死效应，于2007~2014年在环绕长白山国家级自然保护区的环长白山旅游公路、头道环区公路以及白山公路分别选取1条样线，采用直接计数法统计了交通致死的两栖类种类、数量、致死位置，共统计257次，累计调查样带总长2 441km。结果表明：道路致死两栖类种类有5种，累计致死个体数为7 910只，平均致死率为27.9只/ l0km；最容易遭受致死的两栖类动物是中国林蛙(Rana chensinensi)、东方铃蟾 (Bombina orientalis)、中华蟾蜍 (Bufo gargariza)，这三种动物占到致死总数的96.3%；两栖类道路致死高峰期主在8月份，其次较集中出现在4~6月的繁殖期；从年度致死来看，除了中国林蛙和大蟾蜍致死率呈小幅度变化外，其他种类致死率总体呈下降趋势；不同月份两栖类总致死率与交通量显著相关 (r=0.913,p=0.004)。相应的，提出了缓解道路对两栖类动物负面影响的措施。 |

| In order to study the effect of amphibians mortality caused by road traffic, one sample transect was choose separately on the Ring Changbai Mountain Scenic highway, Toudao road and Baishan road in the Changbai Mountain National Nature Reserve from 2007 to 2014. Amphibians road mortality species richnes, number, and location were recorded by direct counting method with the total length of sample survey was 2 441 km and 257 times. The results showed that 7 910 amphibians, belonging to 5 species were recorded as road killed with the average mortality was 27.9/ l0km. The most vulnerable species were Chinese Brown Frog (Rana chensinensi), Oriental Fire-bellied Toad (Bombina orientalis) and Asiatic toad (Bufo gargariza), for the mortality accounting for 96.3% of the total mortality. August was peak period for road mortality of amphibians, and then concentrated in breeding season from April to June. In the view of yearly mortality, all amphibian species tended to decline tendency except for Chinese Brown Frog and Asiatic toad, which only had small extent variation in different years. The monthly mortality was significant correlation with the monthly traffic volume (r=0.913,p=0.004). Accordingly, some protective measures of amphibians were provided. |
