| 摘 要： | 以灰色系统理论为基础,建立了模拟区域内离散结点的灰色有限差分数值模型,并给出了其灰色求解方法。通过对成安县2004-09-25～2006-05-29时段的地下水位模拟,表明运用灰色有限差分模型计算的地下水位为一＂灰带＂,实测水位值正好包含于这个＂灰带＂之中,由此验证了所建立的灰色模型对地下水流模拟结果客观合理。该模型可以将模拟中的一些不确定参数视为一个灰范围,运用该模型对成安进行地下水量开采模拟,预测未来地下水位的动态变化,为研究区域地下水资源的合理开发利用提供了科学依据。 |

| Abstract: | Based on the grey system theory,grey finite difference numerical model of each discreted node is established in modeling region,and grey solving method of the model is given.Modeling groundwater level in Cheng'an from 2004-09-25 to 2006-05-29,the results demonstrates that the groundwater level value solved by the grey model is a grey band but that from measured water level data is precisely inCluded among the grey band.That verifies the modeling results of groundwater flow by the grey model are more objecti... |
