通过对典型黑土区坡面、微型小流域和小流域3个尺度观测场地连续4 a的融雪监测
比较分析了融雪径流发生特征及其所占的比例。结果表明
该区融雪发生和持续时间取决于日最高气温和冬季总降雪量。降雪径流系数远大于降雨径流系数
部分年融雪径流量多于降雨径流量
坡面尺度的径流系数高于小流域尺度的径流系数。小流域的融雪径流最能代表汇入河流中的雪水量。降雪径流系数年际波动大
范围为3%~83.6%
融雪径流量占全年降水径流量的59.3%
在径流观测中不容忽视。
The snow melt runoff in different scale observation sites of slope
mini watershed and small watershed were monitored during past four years in the typical black soil area of Northeast China. The results showed that the beginning and duration of snow melt runoff was determined by the daily maximum temperature and the amount of snowfall in the winter. The runoff coefficient of snowfall was much larger than that of rainfall
and the annual amount of snow melt runoff was even more than that of rainfall in some years. The runoff coefficient in slope scale was larger than that in watersheds. The amount of snow melt runoff in small watershed could figure out the amount of snow melt into river. The runoff coefficient of snow had a large fluctuation
from 3 percent to 83.6 percent during the past four years
and annual mean runoff of snow melt was 59.3 percent of runoff of precipitation. Hence
the snow melt runoff can not be neglected in runoff monitoring.
