Exploration of causality embodies a process of self-redemption that escorts us from the misery of ignorance to the serenity bestowed by knowledge.

研究方向(Research Interest)

径流组分划分河流流量一般可分为快速流和慢速流两个组分,其中慢速流通常被称为基流(Baseflow。基流代表来自地下水或深层土壤水补给的河流流量的稳定部分。通过探究环境示踪剂浓度(如电导率和浊度)与流量之间的关系(即C-Q关系),我们可以准确划分基流在总流量中的占比,从而为有效管理流域水资源、确保生态环境安全提供关键的数据支持。

 

多目标水文模型优化水文模型是分析流域内各种水文过程(如径流、蒸散发、下渗等)的有效工具。这些模型包含一些代表流域特定物理特性的待定参数,这些参数通常需要通过使用足够长时间的径流观测数据进行校准,以确保模拟结果的准确性。然而,仅仅基于观测径流进行单一目标的校准,可能会导致“异参同效Equifinality)”现象,即出现多组参数组合都能产生相似的模拟结果,但其中一些参数的取值可能并不符合物理约束。为了有效解决这一问题,我们可以纳入除径流外的其他水文观测数据(如蒸散发、土壤水分等)进行多目标校准。这样做不仅可以减少“异参同效”现象的发生,还能使水文模型更具物理代表性,从而更好地服务于流域水文模拟实践。

 

大气变量降尺度与误差修正一般网格化的气象再分析数据Climate Reanalysis Data)空间分辨率通常不高于0.1°(约10公里),这使得它们难以准确反映地形对近地面气象条件的复杂调制作用,进而造成山区水文模拟结果的不准确。为了克服这一局限,我们可以结合高分辨率的地形(如高程、坡度等)与地表工况数据(如土地覆盖、植被类型等),并运用物理规律和机器学习算法(Machine Learning),来构建高分辨率的气温、气压、湿度、入射长波辐射、短波辐射、风速和降水数据(分辨率可达1公里或更精细)。这些高分辨率数据将为水文模拟提供更精确的驱动信息,从而提高模拟的准确性。
