摘要
为揭示缺资料黑龙江上游地区洪水过程的降雨径流特征,利用GPM降水数据分析了流域2021年6月的两场典型洪水过程的降雨时空分布特点,通过构建基于遥感驱动的HEC-HMS水文模型,模拟了黑龙江上游洛古河至上马厂区间的洪水过程,定量研究了汇流区间径流与左右岸、干支流的径流贡献,并与2017年和2018年的历史洪水进行对比分析。结果表明:2021年6月两场洪水过程期间的降雨强度大于2017年和2018年历史洪水的降雨强度,降雨的空间分布各不相同。4场洪水过程中,研究区右岸径流贡献较大,以支流呼玛河的径流贡献为主,左岸支流径流贡献较少,主要为区间来水。
In order to reveal the rainfall-runoff characteristics of flood processes in the upper reaches of Heilongjiang river,this study ana⁃lyzed the spatial-temporal distribution characteristics of rainfall during two typical floods by using GPM precipitation data,constructed the HEC-HMS hydrological model driven by remote sensing,simulated the flood processes from Luoguhe to Shangmachang in the Heilongjiang main stream,quantitative studied the interval runoff and the runoff contribution of main and tributary rivers on left and right banks.The re⁃sults show that cumulative the rainfall intensity during the two flood events in June 2021 was greater than that of the historical floods in 2017 and 2018,and the spatial distribution of rainfall varied.In the four flood processes,the runoff contribution of right bank was the larger,and dominated from the Huma River,the runoff contribution from the left bank was less.
