| 摘 要： | 格尔木冲洪积扇右翼浅埋潜水层上、下段出现的水质变异,是在地层含盐背景下,地下水开采扰动和水位上升综合作用引起的。地层含盐量因溶出减少和区域水位下降,水质进一步恶化的可能性较小。格尔木未来水源地应尽可能选择在戈壁带左翼或右翼傍河区。

| Abstract: | The variation of water quality between the upper and lower part of shallowphreatic water in the right-wing of Golmud alluvial-pluvial fun is caused by the comprehen-sive action of groundwater mining disturibance and water level raising under the backgroundof salt bearing strata. The water quality cannot be deteriorated more because the regionalwater level declines and the salt amount dissolved from strata decreases. The future waterre-sources site of Golmud should be chosen at the riverside area of right or left wing of gobibelt. |
