摘要
讨论了长江水质的评价与预测问题.利用多指标模糊概率综合评价和水质指数(W Q I)综合评价等方法分别对长江近两年多的水质状况进行对比,分析,检验与定量综合评价.建立相应的线性规划与线性回归模型,找出主要污染物高锰酸盐和氨氮的分布地区.并对长江未来10年的水质污染趋势进行了预测分析,统计了每年最少处理的污水量.
It is discussed the evaluation and forecast of the Yangtze River water quality. It is compared the state of Yangtze River water quality in recent two years, and evaluated comprehensively by multiple index fuzzy probability, WQI of water quality and so on. Base on it, corresponding model of linear programming and multiple linear repression is constructed. According to comparison and analysis, it comes to conclusion the reign where there are distributed more of pollutions-Ammonia Nitrogen and Permanganate, predict the tendency of pollution of Yangtze River water quality in next ten years, and sum up the least quality of sewage water which should be handled.
