| 摘 要： | 以内蒙古乌梁素海人流水体为研究对象,考虑湖泊水质的随机性和灰色不确定性,以灰色概率统计理论为基础,引人灰色-随机风险率方法,通过计算并分析2006年、2007年和2008年入湖断面各水质参数存在的超标风险性,反映不同水质参数的污染强度和污染历时的变化过程.结果表明,入湖水体总氮总磷浓度超标风险率呈现逐年上升的趋势；总氮...

| Abstract: | With the development of society and economy it is widely believed that water environmental pollution has seriously affected our daily life.Mouth water body of Wuliangsuhai Lake in Inner Mongolia is taken as the research object in this study.To considering randomness and gray uncertainty of lake water quality based on the theory of grey probability and statistics by introducing grey-stochastic risk method,over standard risk of each water quality into water section is been calculated and analyzed from 2006 to... |
