陇西黄土高原石质山区地下水勘查与开发利用探讨

陇西黄土高原位于甘肃省中部,是我国最干旱缺水的地区之一。近年来,在黄土高原区周边及高原内相对隆起的石质山区先后找到了可供利用的地下水,较好地缓解了部分地段的人畜用水。但在开采利用过程中均不同程度出现了水位下降、水量衰减的现象,且幅度较大,制约着该类水的进一步开发利用。本文在对其原因进行分析的基础上,对该类地下水的勘查与开发利用进行了分析和探讨。

Survey and Development of Underground Water in Rocky Mountainous Area of Longxi Loess Plateau

Longxi loess plateau is situated at the central of Gansu Province; it is one of most drought area in China. Recently, utilizable groundwater has been discovered in the rocky mountainous area within and around plateau, it resolved partly demand of local people and livestock.
