摘　　要：子午岭位于鄂尔多斯盆地中南部,“鄂尔多斯盆地地下水勘察”是我国近些年来开展的一项重要的水文地质工作,期间运用多种先进技术方法,对地下水赋存规律取得了好多新的认识。其中发现子午岭地区白垩系地下水的运移与常规的认识不同,高大的地表水分水岭并不完全是地下水的分水岭,这对正确评价白垩系地下水资源奠定了良好的基础,同时勘查工作揭示的这一自然现象,也为广大水文地质工作者正确认识和分析地下水系统有所启发。子午岭仅是地表及浅部环河组地下水的分水岭,而深部洛河组地下水不受子午岭影响,地下分水岭在子午岭以东。白垩系洛河含水组地下水在子午岭以东接受降水和地表水补给后,越过子午岭向西迳流,最终在马莲河排泄。Investigation （in Shaanxi） and research project of undergraound water in the Cretaceous system in Ordos Basin have got the following considerations： the Ziwuling is the water shed between the surface water and shallow water of the Huanhe Formation, and the undergound water in deep-seated Luohe Formation is not affected by Ziwuling. The underground water shed is in the east of Ziwuling. Received replenishment from precipitation and surface water, the Cretaceous underground water in the east of Ziwuling flows over Ziwuling to west and finally to the Malianhe River.
