鄂伦春族世居黑龙江省大兴安岭地区,冬季的冷应激很强,但他们的冷适应水平未见研究报道。本文报告鄂族居民在局部和全身冷暴露时的体温及心血管反应,并与该地边防部队汉族战士比较。鄂族青年组(小于20岁)的反应与汉族战士相似,但壮年及中老年组冷暴露时,可保持较高的肢端温度。认为鄂族具有较强的耐寒力主要是长期适应于严寒所致,而非先天的因素所造成。 Oroqen lived in Daxinganling, Heilongjiang Province. The cold stress was strong in winter, but no research was reported on their cold adaptation level. This article reports the body temperature and cardiovascular responses of residents of ethnic Hubei during local and systemic cold exposures and compared them with the Han border soldiers of the border guards. The reaction of the Youth Minority in Hubei (less than 20 years of age) was similar to that of the Han soldiers, but the limbs and middle-aged and elderly people were able to maintain their extremity temperatures during cold exposure. It is believed that the strong cold tolerance of ethnic Hubei is mainly due to long-term adaptation to severe cold, but not caused by innate factors.
