摘要
拉萨河地区的雨水方程为 δD=7.2 δ1 8O+ 12 .36 ,表现出该地区为较强烈蒸发特征。氢、氧同位素空间分布特征 :墨竹工卡以北 ,δD,δ1 8O东部高 ,西部低 ;墨竹工卡以南 ,δD,δ1 8O东部低 ,西部高。这种区域性分布特征与孟加拉湾降水云气的形成、运移过程及拉萨河地区的自然环境。
The atmospheric precipitation equation of δD = 7.2δ 18 O + 12.36 indicates intense vaporation in the Lasa River Area.The sptial distribution of isotope H and O is characterized by higher δD and δ 18 O for the east area of the northern Mozhugongka and lower for the west area of northem Mozhugongka.In the southem Mozhugongka,δD and δ 18 O are higher in the westem area than in the eastem area.The distribution character is related to the formation and migration of precipitation floating clouds and to the natural evironment and climate condition in Lasa River area.
