摘要
北山地区是我国严重干旱缺水地区之一。区内基岩分布面积高达70%以上,是重要的裂隙含水介质。风化裂隙水分布广泛,单井涌水量一般小于20 m3·d-1。风化裂隙水的富集主要取决于岩性、地形和构造条件的组合。岩性和构造是风化裂隙水富集的基本条件,地形是控制补给和富集的重要因素。
Beishan area is one of the typical drought and water lacking regions in China. The bedrock occupies more than 70% of total outcrop, and comprises important fractured water-bearing medium. The weathering fracture water is widely distributed in the area. Water yield of single well is mostly less than 20 m3. d-1. The enrichment of weathering fracture water mainly depends on the combination conditions of lithology, topography and geological structure. The lithological feature and geological structure are the foundation of weathering fracture water enrichment, and the topography is an important factor that controls recharge and enrichment of weathering fracture water in the area.
