| 摘 要： | 由于地下水埋深受气象因素影响呈现年周期变化，且因气候的波动和生态环境的变迁，使地下水埋深在不同年份相同阶段并不相同。将时间序列的季节模型用于人民胜利渠古黄河背河洼区、漫滩区月平均地下水埋深动态建模之中。计算结果表明，模型为疏系数季节模型，模型精度显著高于自回归模型。

| Abstract: | The groundwater table is always varied in the same stage of different year because the groundwater table is changed yearly and periodically effected by the meterological factors and the fluctuating weather and the variable ecologic environment. The seasonal model of time series is used for modelling the monthly average groundwater table of the depression area of the old yellow river in the People' s Victory Canal District. The calculation results show that the precision of jibe dispersed coefficient seasonal model is much higher than the autoregression model. |
