Abstract:

【Abstract】　Objective　To study the distribution,species and faunal regions characteristics of siphonaptera in Liaoning province. Methods　The principle and method of zoogeography were used in this study. Results　 Nuruer Tiger Mountain is the watershed of Daling river and the upstream of the Liaohe river. Because of its obstruction to warm air current, the climate on both side of watershed changed differently. It was found that the zone of   siphonaptera and host animals fauna elements changed through investigation, especially the quality change of a representative special species. So, it suggested that the boundary of Chinese zoogeographic fauna of Xinjiang and Inner Mongolia and East China region in northwest of Liaoning province was amended, and the siphonaptera area of Liaoning province was divided into 7 province and 6 states. Conclusion　The fauna characteristics should not judge according to merely the fauna element and the change of representative special species, the unity of animals distribution and environment conditions also plays an important roles.
