辽宁省蚤类地理区划研究

目的调查研究辽宁省蚤类分布、种类及区系划分特征。方法采用动物地理学原理和方法。结果努鲁儿虎山脉是大凌河与辽河上游的分水岭，其南麓形势雄伟，由于对暖气流的阻挡，使分水岭两侧气候发生一定变化。通过调查研究发现，这一地带蚤类及宿主动物的区系成分发生了改变，尤其是具有代表性的特有种发生了质的改变。因此建议对（1998）中国动物地理区划蒙新区与华北区在辽宁省西北部划界线进行修正，并将辽宁省蚤类区系细划为7个省、6个州。结论判定某地区动物区系性质时，不能单纯依据动物的区系成分，代表性的特有种类发生的变化，认为动物分布和环境条件的统一性同样具有重要意义。

The regional area of siphonaptera in Liaoning

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.
