| 摘 要： | 为了分析不同下垫面材料径流污染物的输移变化，以ρ（CODCr）为指标，在室内进行了6种下垫面材料（原土夯实、钠盐处理土面、水泥土、塑料薄膜、三七灰土以及混凝土）径流试验，分析了ρ（CODCr）随着径流历时的变化情况．综合考虑下垫面的集流效率及对径流污染物的削减作用，确定适合庭院式集流场的最优下垫面．

| Abstract: | In order to analyse the transportation variation of the runoff contaminants of different kinds of underlaying surface materials, the laboratory experiment is carried out with the norm of ρ（CODCr） to study the runoff contaminants of six kinds of underlaying surface materials, which are the tamped crude soil, sodium salt treated soil, cement soil, plastic film, lime soil（the ratio of lime to soil is 3：7）and concrete. The variations of ρ（CODCr） for different runoff duration are analysed. Then taking the affluxion efficiency and removing effect on runoff contaminants into consideration, the optimal underlaying surface for courtyard affluxion field is determined finally. |
