摘要
根据塔克拉玛干沙漠科学考察,运用环境同位素水文地质学方法,对沙漠中现代河床、古河道、沙漠下伏古冲洪积洪泛平原三种典型地段地下水的补给源、径流特征、排泄途径等综合分析,表明沙漠中大部分地下水来源于周边细土平原带的侧向补给,河水影响范围有限,降水影响极小。地下水径流因条件差异而不同,排泄以蒸腾作用、毛细蒸发及溢出蒸发三种方式为主。
The artical in terms of environment isotop hydralogy and geological survey synthesize have analysed three ground water of typical area where modern floor, ancient bloor and ancient alluvial-flood deposit plain underlain desert in Taklimakan desert. It is proved that a lot of ground water come from side charge around clay plain zone, River to flow into desert limited affect ground water precipitated water affect little. Ground water character by run off don't like eacher other because medium factor have difference. There are three primary discharge way, transpiration, capillary evoporation, overflow evoporration.
