摘要
含水层给水度μ值代表单位面积含水层中潜水位每下降一米时，饱水岩层所能释放出来的水量。所以在地下水资源评价中，给水度μ值起着决定性的作用。本文是在同一个水文地质单元，利用历年地下水动态资料和非稳定流抽水试验资料，采用不同方法，通过实例推求的μ值误差不大，可供有关单位参考使用。
specific yield μ value of aquifer represents water volume of saturated aquifer can releasewhen groundwater level of aquifer decrease 1 meter persquare. In evalution of groundwaterresources,the specific yield μ value plays an important role. The μ value was infered at asame hydrogeological unit,using the groundwater moving data and pumping test data of un-steady flow,adopting different ways and the error of μ value is small,it can be refered andused bv correlated units.
