In order to accurately judge the start and end time of snowmelt period, the upstream of the Danba basin, the main source of snowmelt runoff in Daduhe River, was taken as an example. Based on hydrometeorological data from 2009 to 2020, set pair analysis method, systematic clustering method and K-means clustering method were used to calculate the snowmelt period in the dry season (November to the next May), and the rationality of the staging results was evaluated. The division scheme of final snowmelt period in the basin was determined. The results show that the main snowmelt period is from January 11 to May 10, the preceding period is from November 1 to January 10, and the following period is from May 11 to May 31, which is the beginning period of rainfall runoff (there is still some snowmelt runoff). The research results can provide reference for the classification of snowmelt periods in high latitude areas.

为准确判断融雪期起止时间,以大渡河融雪径流主要来源区的丹巴以上流域为例,基于2009~2020年的水文气象资料,分别采用集对分析法、系统聚类法和K-means聚类法对流域枯季(11月~次年5月)融雪期进行分期计算,并对分期结果进行合理性评估,确定流域最终融雪期划分方案。结果表明,大渡河丹巴以上流域的主融雪期为1月11日~5月10日,其前的11月1日~1月10日为退水期,其后的5月11日~5月31日为降雨径流开始期(仍有部分融雪径流)。研究结果可为高纬度地区的融雪期划分提供参考。

为准确判断融雪期起止时间,以大渡河融雪径流主要来源区的丹巴以上流域为例,基于2009~2020年的水文气象资料,分别采用集对分析法、系统聚类法和K-means聚类法对流域枯季(11月~次年5月)融雪期进行分期计算,并对分期结果进行合理性评估,确定流域最终融雪期划分方案。结果表明,大渡河丹巴以上流域的主融雪期为1月11日~5月10日,其前的11月1日~1月10日为退水期,其后的5月11日~5月31日为降雨径流开始期(仍有部分融雪径流)。研究结果可为高纬度地区的融雪期划分提供参考。

In order to accurately judge the start and end time of snowmelt period, the upstream of the Danba basin, the main source of snowmelt runoff in Daduhe River, was taken as an example. Based on hydrometeorological data from 2009 to 2020, set pair analysis method, systematic clustering method and K-means clustering method were used to calculate the snowmelt period in the dry season (November to the next May), and the rationality of the staging results was evaluated. The division scheme of final snowmelt period in the basin was determined. The results show that the main snowmelt period is from January 11 to May 10, the preceding period is from November 1 to January 10, and the following period is from May 11 to May 31, which is the beginning period of rainfall runoff (there is still some snowmelt runoff). The research results can provide reference for the classification of snowmelt periods in high latitude areas.
