黄河中游为我国黄土主要堆积区。因黄土土质疏松,易于侵蚀,故沟系发育,水土流失严重。加之气候干燥少雨,属半干旱气候带,缺水问题严重。尤其是西北部梁峁区,不少地方人畜用水都很困难。过去人们总认为黄土中无水,有一种说法是,“黄土透水不含水”。近年来随着工农业建设的迅速发展,需水量日益增大,迫使人们不得不进一步探索大自然的奥密——寻找地下水。可喜的是, The middle reaches of the Yellow River are the major loess accumulation areas in China. Loess due to loose soil, easy to erode, so the development of furrows, soil erosion serious. Coupled with the dry and dry climate, is a semi-arid climate zone, water shortage problem. In particular, Liangbei District in the northwest, many local people and livestock are very difficult to use. In the past, people always thought that there was no water in the loess. There is a saying that “loess is permeable to water without water.” In recent years, with the rapid development of industrial and agricultural construction, water demand is increasing day by day, forcing people to further explore the mysteries of nature - looking for groundwater.
