| 摘 要： | 为了有效理解滇池非点源入湖过程,选择滇池流域宝象河开展暴雨径流初始冲刷效应的初步研究.2009年雨季,在其干流沿程上、中、下游设置3个断面进行了初期3场暴雨及河道水量、水质同步观测,并提出降雨净冲刷量、负荷净冲刷量以及净冲刷径流平均浓度EMCn的定义与计算方法.结果表明,宝象河TSS、TN、TP、高锰酸盐指数的EMCn、累积曲线M(V)随着河道沿程不透水地面比例和人口规模的增加而提高,TSS、TP负荷贡献率及其M(V)与降雨强度的变化趋势一致,而TN和高锰酸盐指数负荷贡献率则与降雨量表现正相关,其中TN中NO3--N所占比例随着降雨事件次数增加而逐渐降低;此外,提出的EMCn也被证实能有效消除各点位的基流及其负荷影响,相对冲刷径流平均浓度,更为真实反映且能放大沿程断面间、不同降雨事件间的暴雨初始冲刷效应的差异. |
| 关 键 词： | 河流暴雨径流 冲刷径流平均浓度 富营养化 非点源污染 滇池 |
