青藏高原强紫外辐射适应机制研究进展

ADVANCES IN RESEARCH ON THE ADAPTATION MECHANISM OF STRONG ULTRA VIOLET RADIATION ON THE QINGHAI-TIBET PLATEAU

紫外辐射常来自于太阳光照射,若在可控范围内可起到杀菌作用,但过量紫外线辐射会引起生物体表皮红斑效应、色素沉积、加速老化等;青藏高原由于其较高的海拔和复杂的生态环境,紫外辐射程度较强,其对于生物有较大的影响,使得生活在青藏高原上的生物在较长时间内形成了各自应对强紫外辐射的机制。本文从青藏高原特殊的地理环境、强紫外辐射的影响入手详细阐述了生物对于此环境下的适应机制以及研究进展,为相关领域的研究提供基础,同时也可促进紫外辐射相关预防措施和治疗方案的研究。

Ultraviolet radiation often comes from sunlight,which can playa bactericidal effect ina controlled range,but excessive ultraviolet radiation can cause epidermal erythema effect,pigment deposition,accele rated aging and so on.Because of its high altitude and complex ecological environment,the Qinghai-Tibet Plateauhasa strong degree of ultraviolet radiation,whichhasa great impact on organisms,whichmakes the organisms living on the Qinghai-Tibet Plateau form their ownmechanisms to cope with strong ultraviolet radiation fora long time.Starting with the special geographical environment of the Qinghai-Tibet Plateau and the influence of strong ultraviolet radiation,this paper expounds in detail the adaptationmechanism and research progress of organisms to this environment,which provides the basis for the research in related felds.at the same time,it can also promote the study of preventivemeasures and treatment schemes related to ultraviolet radiation.
