补充资料：径流
| 径流 runoff 大气降水形成的，并通过流域内不同路径进入河流、湖泊或海洋的水流。习惯上也表示一定时段内通过河流某一断面的水量，即径流量。按降水形态分为降雨径流和融雪径流。按形成及流经路径分为生成于地面、沿地面流动的地面径流；在土壤中形成并沿土壤表层相对不透水层界面流动的表层流，也称壤中流；形成地下水后从水头高处向水头低处流动的地下水流。广义上，径流还包括固体径流和化学径流。径流是引起河流、湖泊、地下水等水体水情变化的直接因素。其形成过程是一个从降水到水流汇集于流域出口断面的整个过程。降雨径流的形成过程包括降雨、截留、下渗、填洼、流域蒸散发、坡地汇流和河槽汇流等。融雪径流的形成需要有一定的热量，使雪转化为液体。在融雪期间发生降雨，就会形成雨雪混合径流。影响径流的因素有降水、气温、地形、地质、土壤、植被和人类活动等。 |
