This paper introduces briefly the same basic concepts about the grey systematic theory found by professor Deng Julong , and tries to forecast the ground water regime by means of the regime prediction model ( DM 1, 1 ) in this theory. In this paper predictable mathematical calculations have been made for the quoted long-term obsevational data of ground water in Baoding area of Hebei province, and the calculated results have been contrasted with the practically obsevational values. The results indicate that the model DM ( 1, 1 ) for the tendentious prediction of the systems is of good effects and the general water table level tendency of water regime in this area as drop-ping year by year.

本文扼要地介绍了邓聚龙教授创立的灰色理论的某些基本概念,并试图用该理论中的动态预测模型(DM(1.1))来进行地下水动态预测。文中对所引用的河北保定地下水长期观测资料进行了预测演算,并将演算结果同实测值做了对比。结果表明,DM(1.1)模型对系统的趋势性预测效果良好,本区地下水动态总的水位趋势是逐年降低的。

辽西位于华北板块北缘,辽西隆起带上,辽西地震活动与华北密切相关,在华北第四地震活动期中,辽西处于磁县—朝阳地震带和丹东—朝阳地震条带交汇处。根据灰色理论预测表明,辽西近期已不大可能发生六级左右地震,但其周围地区近几年很可能发生七级左右地震。

According to the grey system advanced by Prof. Deng Julong, this article analyses the groundwater system, and regards that the groundwater system is a grey system with a part of known and a part of unknown information.The output of this system is the water level data which we measured at a time. The periodical groundwater level data coming from standing observation wells throughout an area form a time sequence composed of the outputs in the times going on. The method of the recognition of residual errors through simple function in grey system is applied to handle the time sequence by the author. This method js based on grey system theory.Sets model DM(n, h) repeatedly. Then a residual model DM is set up using the differences of predictive and actual valnes obtained before and consequently the correct residual is worked out.By this way the precision of prediction may will be increased, The superposition of trend separated respondent model and residual separated respondent model leads to the dynamic model of the groundwater level of this area. The coincidental precision is high and the result of prediction is very satisfactory.

本文从我国学者邓聚龙教授提出的灰色理论出发,对地下水系统进行分析,认为地下水系统就是一个部分信息已知、部分信息未知的灰色系统,某一时刻我们测得的水位,就是该系统的输出。而各地区建立的常观井定时收集的地下水水位值,也就是系统在每时刻的输出所构成的动态时间序列。对于这种时间序列的处理,作者采用灰色预测中的单段函数残差辨识方法。该法以灰色理论为基础,多次建立灰色模型DM(n,h),将每次建模得到的预测值与实测值之差,再建立残差DM模型,得到修正残差,以提高预测精度。趋势离散响应模型与残差离散响应模型相叠加,便得到了某区地下水水位的动态模型,其拟合精度很高,预测结果十分令人满意。
