【摘要】 陇西黄土高原地区地下水的形成、埋藏受地质地貌条件的控制,基本上可分为黄土孔洞裂隙潜水,基岩裂隙潜水,河谷及断陷盆地砂砾石层孔隙潜水等类型。各种类型的地下水因埋藏条件,含水介质及分布位置的差别,因此,有着各自不同的补给、径流、排泄特征及由此所决定的特殊的动态特征。更多还原

【Abstract】 The formation and burial of ground water in west Gansu on the loess plateau are controlled by geological and geomorphological conditions. It can be divided into such types as latent water in loessal holes and slits, latent water in bedrock slits and porous latent water in river valleys and sand layers in fault basin, etc. Ground water of various kinds may have various behavious of supplements, runoff and drainages because of burial conditions, water-bearing medium as well as difference in distributing locations based on which the special dynamic behavious are determined.更多还原
