冰雪融水补给多发生在气温最高的夏季。 其特点是单位面积出水率高,这是由于在冰川发育的高山地区,蒸发少的缘故。 冰雪融水补给主要指在流域内的高山地区,永久积雪或冰川融水的补给。在干旱、半干旱或者部分较湿润的山区,冰雪融水是河流补给的重要组成部分,在某些特殊地区(我国新疆塔里木盆地),甚至成为水量的唯一源泉。
水源补给以冰雪融水和降雨混合为主,部分地区有地下水补给,形成了大量的沼泽草地和湖泊。
Water supply comes from the melting water of ice and snow as well as rainfall. Some places have groundwater in the form of swamp lawn and lakes.
结果表明,内陆河多为高山冰雪融水和雨水混合补给型河流,外流河多为以雨水补给为主的河流;
The results show that the inland rivers are mainly supplied by mountain snowmelt and precipitation, and the outflow rivers are mainly supplied by precipitation.
