摘　　要：爬行动物是受道路影响的主要野生脊椎动物类群之一,2019—2020年,采用路巡调查法对云南省普洱市思茅区爬行动物路杀现象进行了调查。结果发现,路杀爬行动物有7科22种100只,钝头蛇科的横纹钝头蛇Pareas margaritophorus、眼镜蛇科的银环蛇Bungarus multicinctus是路杀数量最多的物种,包括2种国家二级重点保护野生动物:闪鳞蛇Xenopeltis unicolor和三索蛇Coelognathus radiatus。爬行动物的路杀有3个高峰时间段,7:00—10:00时是最集中的路杀时间段。温度20—25℃是最集中的路杀温度范围。进一步的分析发现,爬行动物的路杀与其活动节律有关,7:00—10:00时的晒阳行为可能是路杀的主要诱因。Among the community of vertebrates living in the natural environment, reptiles are more prone to be affected by various road conditions like vehicle collisions which severely threaten their life. From 2019 to 2020, road driving survey was conducted on the roadkill of reptiles to describe road-kill composition and to estimate the main reasons of road-kills in Simao District, Pu′er City, Yunnan Province. The results showed that there were recorded 100 carcasses of reptiles belonging to 22 species within 7 families, among them Pareas margaritophorus of Pareatidae and Bungarus muliticinctus of Elapidae were more vulnerable to road mortality. It was also notable that two species of State Key Protected Wild Animal Species, Xenopeltis unicolor and Elaphe radiatus, were also been found in roadkill in this case. There were three peaks of reptile roadkill, 76 carcasses of reptiles recorded at 7:00—10:00, probably due to their higher activity, which was the hot moment of roadkill. The temperature ranges of reptiles roadkill were concentrated between 20—25 ℃. Furthermore, considering the physiological needs of reptile, such as thermoregulation, reptiles roadkill were coincident with their activity rhythm, especially during the peak period of basking between 7:00—10:00, which made them more prone to collisions.
