| 摘 要： | 依据长江流域水质监测资料,选用具有代表性的主要因子pH、DO、高锰酸盐指数、NH3-N,采用综合水质标识指数模型对长江流域进行了定量综合评价,评价结果表明,影响长江流域水质的主要污染因子是NH3-N和高锰酸盐指数;定量综合评价显示长江流域总体水质为Ⅱ类水,但有恶化为Ⅲ类水的趋势。据此,揭示了水质的时空变化规律。根据监测数据和水质报告,采用灰色模型预测了未来10年长江流域各类水质比例,预测表明,Ⅲ类以上可饮用水的比例在逐年减少。

| Abstract: | Based on monitoring data of water quality, main factors including pH, DO, CODMn and NH3-N were chosen to quantitatively assess water quality of the Yangtze River by identification index model of water quality. Results showed that overall water quality of the Yangtze River satisfies Class II, but it is deteriorating to trend of Class III, with NH3-N and CODMn as major pollutants, which accordingly revealed spatial and temporal variations of the basin water. Gray model was also used to forecast water quality ... |
