“潜水位变幅带给水度”是表示潜水位发生变化时,贮存或释放出地下水能力大小的一个参数值。它不仅在浅层地下水资源评价工作中占有重要地位,也是农田灌溉、排水工程规划设计工作中必不可少的重要参数。八二年以来,国内一些单位正在使用简易筒测法求潜水含水层的疏干给水度。八三年七月,在淮、海河流域地下水资源工作会议上,山东代表介绍了坑测法求潜水含水层疏干给水度的实验方法,受到与会代表的重视,认为此法简单易行,有其 “Subduction zone amplitude bring water” is a parameter value indicating the size of the ability to store or release groundwater when the diving position changes. It not only plays an important role in the evaluation of shallow groundwater resources, but also is an indispensable parameter in farmland irrigation and drainage engineering planning and design work. Since 1982, some units in China are using simple tube method to find the water supply for the diving aquifer. In August 2003, at the Huaihe River Basin Groundwater Resources Conference, a representative of Shandong introduced the experimental method for determining the depth of water supply for the submerged aquifer using the pit test method. The delegates emphasized that this method is simple, its
