| Abstract: | [中文摘要]：采用时间序列分析法对位于石羊河下游的民勤县地下水水位进行了模拟预报。结果表明，模型总体拟合较好，精度较高，平均相对误差仅为0．086％。但由于人类活动影响加剧，总体上模型预报值较实际值偏大，尤其表现在水位极小值处。因此，随着开采量的不断增大，为了提高预报精度，需要随时对模型进行修正。同时针对水位下降过快的现状，有关部门应采取相关措施进行遏制。
[英文摘要]： This paper simulated and predicted groundwater level of Minqin County located m the downstream Shiyang River by time-series analysis method. The results show that the model generally had a good effect and high precision, and its average relative error was only 0. 086%. HOwever, due to the more and more severe influence of human activities, the predicted values were generally larger than the observed values, especially at the small-extreme values of the water level. Therefore, with the successive increase of the exploitation volume, in order to raise the prediction precision, the model needs revising at any moment. Meanwhile, considering the status of too fast decrease of water level, some measures should be taken to prevent it by the related departments. |
