为评价黄河干流中卫新墩断面近年水质状况及水质变化趋势,文章采用综合污染指数法对新墩断面2004年以来的水质状况进行了分析。结果表明:新墩断面水质达到功能区水质要求,受到轻微污染,水质一般。在此基础上,文章利用GM(1,1)模型,借助Matlab软件,拟合了新墩断面未来水质污染变化方程,得出了新墩断面未来水质将进一步好转的结论。
為評價黃河榦流中衛新墩斷麵近年水質狀況及水質變化趨勢,文章採用綜閤汙染指數法對新墩斷麵2004年以來的水質狀況進行瞭分析。結果錶明:新墩斷麵水質達到功能區水質要求,受到輕微汙染,水質一般。在此基礎上,文章利用GM(1,1)模型,藉助Matlab軟件,擬閤瞭新墩斷麵未來水質汙染變化方程,得齣瞭新墩斷麵未來水質將進一步好轉的結論。

The water quality of the Xindun section is analyzed by comprehensive pollution index method since 2004in order to evaluate the Yellow River mainstream Zhongwei Xin dun section in recent years ,the water quality condition and water quality change trend ,.The re-sults show that Xindun section water quality can meet the requirements for quality function by slight pollution , water quality general.On this basis, using GM (1, 1) model, with the aid of Matlab software, fitting Xindun section future water pollution change equation , it is conclu-ded that Xindun section water quality will further improve conclusion in the future .
