根据老虎沟冰川流域2011年强消融期(强消融期指7-8月份)的水文气象资料,分析了老虎沟冰川流域径流及径流温度的日变化过程和径流、径流温度与气温、降水之间的关系。结果表明:老虎沟冰川流域7月气温在早晨8:00左右最低,17:00达到最高;7月冰川径流在10:00左右最小,在18:00左右达到最大值。7月流量最高值约滞后气温最高值1h左右,流量最低值约滞后气温最低值2h左右;降水对径流既有正反馈也有负反馈,降水发生时,流量有可能增加也有可能减少。冰川径流温度主要分三个阶段,第一个阶段是前一天晚上20:00左右到8:00左右,这段时间的冰川径流温度变化很小,且温度始终处于低值;从8:00到12:00径流温度持续升高,12:00左右径流温度达到日最高值;12:00到20:00左右径流温度逐渐缓慢降低。径流温度和气温之间有较一致的起伏关系,但是冰川径流某一时刻的平均温度起伏很小且温度低,最低温度为0.1℃、最高温度为0.9℃。 According to the hydrological and meteorological data of the strong ablation period (July-August of July in August) of the glacial-glacier basin in Laogougou, the diurnal variation of runoff and runoff temperature, runoff, runoff temperature, temperature and precipitation in the glacialgou glacier basin were analyzed. Relationship. The results showed that the temperature of July in the glacier valley of Laohugou reached the lowest at about 8:00 in the morning and reached the highest at 17:00. The July glacier runoff was the smallest at 10:00 and reached the maximum at about 18:00. In July, the maximum value of the lagged temperature is about 1 h, and the lowest value of the lag temperature is about 2 h, which is the lowest lagging temperature. Precipitation has both positive and negative feedback on runoff. When precipitation occurs, the flow rate may increase or decrease. Glacial runoff temperature is mainly divided into three phases, the first phase is about 20:00 the night before to about 8:00, during this time glacier runoff temperature changes is small, and the temperature is always low; from 8:00 to 12:00. The runoff temperature continued to rise. The runoff temperature reached the daily maximum at about 12:00. The runoff temperature slowly decreased from 12:00 to 20:00. There is a more consistent fluctuation between runoff temperature and temperature, but the mean temperature fluctuation at a glacial runoff is small and the temperature is low. The minimum temperature is 0.1 ℃ and the maximum temperature is 0.9 ℃.
