【摘要】 本研究利用美国环境保护局(USEPA)推荐的WASP水质分析模拟软件,对湘江株洲段2009年的镉浓度进行动态模拟,并进行总量控制的情景分析。对水文条件变化和源强变化2种情景下的河道镉浓度进行了预测。结果表明,WASP模型能较好重现镉浓度的时间变化规律。情景分析表明,水文条件和源强条件对镉浓度的影响在霞湾和马家河断面较为明显,且在枯水月份表现得更为明显。更多还原

【Abstract】 Dynamic simulation of cadmium concentration and the scenario analysis of cadmium total control in Xiangjiang River in the Zhuzhou City in 2009 was studied by using the WASP modle. WASP model is a water quality analysis simulation software recommended by USA Environmental Protection Agency. River cadmium concentrations in two scenarios of change on hydrological conditions and source strength were predicted. The results showed that the WASP model could well reproduce the time variation of Cd concentration. Scenario analysis showed that the influence of hydrologic and source strength conditions on the cadmium concentration was obvious in the Xiawangang and Majiahe section,and the performance was more obvious in dry months.更多还原
