摘要: 使用实地观察与样线调查法,以广东罗坑自然保护区的鳄蜥 Shinisaurus crocodilurus为研究对象,研究鳄蜥在春、夏、秋三季的移动情况,并分析其影响因子。结果表明:鳄蜥个体间单次移动距离差异极显著(F=38.184,P<0.001)。从季节上看鳄蜥的单次移动距离分别是,①春季:雄性成体>幼体>雌性成体>亚成体;②夏季:雄性成体>亚成体>雌性成体>幼体;③秋季:雄性成体>亚成体>雌性成体>幼体。往溪沟上游和下游的最大移动距离:雄性成体>亚成体>幼体>雌性成体。不同季节影响鳄蜥发生明显移动的因子不同,应根据鳄蜥不同季节的移动特点来制定相应的保护管理对策。

关键词: 鳄蜥, 移动, 影响因子

Abstract: By field observation and sample line survey, the movement patterns of Shinisaurus crocodilurus in spring, summer and fall at Luokeng Nature Reserve in Guangdong province of China, were studied and the influencing factors on it were analyzed. The results showed that: the single moving distance among individuals is significant different (F=38.184, P<0.001). The single moving distances of S. crocodilurus among different age group were different: ① In spring, male>juvenile>female>subadult; ②In summer, male>subadult>female>juvenile;③ In fall, male>subadult>female>juvenile. The maximum moving distance among the age group toward the upstream and downstream were also different: male>subadult>juvenile>female. Effecting factors on the movement of S.crocodilurus were different among the three seasons. The corresponding management strategies should be made according to the moving characteristics of S. crocodilurus in different seasons.

Key words: Shinisaurus crocodilurus, movement, influencing factors
