本文是通过分析甘肃董志塬西峰地区的一组抽水试验的资料,来探讨塬区黄土含水层饱水带地下水赋存特征及其运动规律。目前,对黄土层中地下水赋存状态的认识尚不一致,抽水试验之后,用现有公式计算参数,往往不敢确信计算的结果。这些均说明黄土层饱水带内水的赋存状态及运动规律,还不十分清楚。这个问题是黄土地区地下水资源评价的重要基础,因此研究黄土含水层中地下水的运动规律、不论是从理论上还是从实践上都是有意义的。
This article is based on the analysis of a group of pumping tests in the Xifeng area of Dongzhi Plateau in Gansu to investigate the occurrence and movement of groundwater in the loess aquifer in the highland. At present, the understanding of groundwater occurrence in the loess layer is not consistent. After the pumping test, the parameters are calculated by the existing formulas, and the results of the calculation are often not convinced. All of these show that the occurrence and movement of water in the saturated water zone of loess plateau are not yet clear. This problem is an important foundation for groundwater resources evaluation in the loess area. Therefore, studying the movement law of groundwater in the loess aquifer is of great theoretical and practical significance.
