水文学前沿科学问题之我见

认为水文时间序列年际演变、降雨空间分布及动态变化、水文现象与下垫面的关系、优先流、坡面流、水文尺度转换、水文模型的"异参同效"、水文非线性等问题是当前面临的主要水文学前沿科学问题。论述这些问题的科学内涵、突破的可能切入点,以及对水文学进一步发展的推动作用。指出水文学的前沿科学问题应与时俱进。期待有更多的学者,尤其是青年学者来关心、发现、探讨水文学前沿科学问题。

Discussion of some frontier problems in hydrology

The main frontier problems in hydrology at present are long-term variation of hydrologic time series, spatial distribution and dynamic variation of rainfall, the relationship between a hydrologic phenomenon and the underlying surface, preferential flow, overland flow, scale transformation, equifinality for different parameters, and hydrologic nonlinearity. The scientific content, breakthrough point, and contributions to further development of hydrology are analyzed with regard to these frontier problems in hydrology. These problems should be studied further. More researchers, especially young ones, will be expected to be concerned with, discover, and discuss these frontier problems in hydrology.
