摘　　要：用最小二乘法生成一个低阶多项式方程组来拟合水库水位——库容关系曲线,并用电子表格求解此多项式方程组。此方法被应用于绘制清江水布垭水库的水位——库容关系曲线,其相对误差小于5%。A low order polynomials equation set is generated by least squares method to fit with the stage-storage curve of reservoir.The equation set is solved by electronic spreadsheet.This method is applied in working out the stage-storage curve of Qingjiang Shuibuya reservoir.The relative fitting error is less than 5%.

关 键 词：电子表格 拟合 库容曲线
