摘　　要：2003年11月～2004年9月在安徽省扬子鳄繁殖研究中心,观察了人工养殖的成年扬子鳄(Alligator sinensis)在饲养池和模拟自然生态环境的繁殖区中越冬后的繁殖行为.结果表明,在与扬子鳄自然洞穴的温度和水分条件相似但其他条件相差很大的人工环境中冬眠的扬子鳄具有繁殖能力.越冬后,这些鳄只能在具备其栖息地环境特点的场地成功繁殖,但不能在不具备这种环境特点的场地成功繁殖.本研究拓展了扬子鳄的人工繁殖技术,为扬子鳄人工繁殖场地的兴建提供参考资料.During the November of 2003 and the September of 2004, reproductive behavior of adult Chinese Alligators living in the artificial pool and the breeding region being imitated its habitat was observed in Anhui Research Center of Chinese Alligator Reproduction after artificial wintering. The results show that adult Chinese Alligators had a reproductive ability when they hibernated in the artificial surroundings with similar temperature and moisture content of their natural holes while with very different other conditions of the holes. After artificial wintering, these alligators could succeed in reproduction only in the field having an environmental character of its habitat, and couldn＇ t do in the other fields. This research is a development for the artificial reproductive technique of the Chinese Alligator, and will supply a reference data for the construction of its artificial breeding field.
