摘要
运用统计学方法，以潜水位的时间序列为基础，通过对该序列的一阶、二阶统计量（均值Ｘ、方差σ２）分析，确定估计的置信区间宽度与观测数之间的关系，在此基础上。
Using the statistical method and taking the time series of groundwater level as a basis, the relationship between the width of confidence interval and observed data is estimated, according to the analysis of first order, second order statistical values of the series Through the estimation, optimum observation frequencies are determined in accordance with the width of confidence interval established by the requires of observation precision. For confined water especially main pumping beds where water levels have been continuously declined by violent overload mining, the method above mentioned cannot be used to optimize estimation, and their optimum operation is to be researched further.
