摘要
青藏公路沿线发育着三个时期的风砂堆积物。其成因主要是寒区特殊的表生作用——广义的寒冻风化作用。盖砂层对于辐射平衡、热量平衡、水份状况、植被条件、冻土生存以及其本身和相邻地区的环境都有着重大的意义。
There are 3 periods of sand deposit along Qinhai-Xizang Highway
that originated from a particular hypergenesis in cold region, cryogenic
weathering. The sand deposit has important influences on many environmental
elements, such as radiation balance, thermal equilibrium, hydrologic
condition, vegetation etc, and also affects the formation and preservation
of frost soil and permafrost environment.
