长江水质评判及预测的数学模型

The mathematical model to the water quality evaluation and predication of Yangtze River

长江水质的污染程度日趋严重,为了保护长江水资源,必须对长江水质进行评价和预测,进而采取措施来治理水质的污染。本文运用模糊数学理论建立了"长江流域水质综合评判"模型,对长江水质进行了全面的定量的综合评判。应用灰色系统理论,建立了灰色预测模型,从而科学地预测出长江未来水质污染的发展趋势。

The pollution of Yangtze River becomes gradually serious. In order to protect the water resources of the river, some measures must be adopted to deal with the pollution after evaluating, estimating the fluid matter. In this paper, making use of the fuzzy mathematics theories to build up the＂ integrated adjudication of the fluid matter of Yangtze River ＂ model, the fluid matter of the river is adjudicated in an overall fixed amount way. Applying the gray system theories to build up the gray predicting model, the development trend of the pollution can be predicted with science ground.
