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。
Objective To investigate the distribution, species and flora of fleas in Liaoning Province. Methods using animal geography principles and methods. Results The Nulu child tiger was a watershed in the upper reaches of the Daling River and Liaohe River. The situation at the south foot of the mountain was magnificent. Due to the blockage of the warm air flow, the climate on both sides of the watershed changed a certain amount. Through investigation and study, it was found that the fauna and host fauna of this area changed their fauna composition, especially the endemic species. Therefore, it is suggested to amend the boundary of Mongolia Animal Husbandry District (1998) and North China District of Liaoning Province in the northwest of China, and divide the Fleas of Liaoning into seven provinces and six states. Conclusion When deciding on the fauna characteristics of a certain area, we can not simply consider the changes of the fauna and representative endemic species. It is also of great significance that the distribution of animals and the environmental conditions are of equal significance.
