摘　　要：应用杨赤中滤波推估法,利用二项系数加权游动平均对观测值序列进行逐遍滤波,建立估值数学模型,求得各个方格中心高程估值。再由水库工程的溢洪道高程设计值与各方格中心高程的差值,求得各方格的体积,汇总即得库容量。讨论了不规则边界处理算法。With Yang chizhong's filtering estimation method, the filtering of the observed value sequence is made once and again by binomial coefficient weighted moving average. The mathematical model of the estimate value is established and the elevation difference of each square grid center is derived. According to difference between design elevation of reservoir' spillway and elevation of each square grid center, the volume of each square grid is calculated and collected, the reservoir cubage is obtained accordingly. The processing algorithm of anomalistic boundary is discussed.
