目前,无资料地区的水文研究已经成为了国际水文学界水资源水环境研究的热点问题之一。当前国际上解决无资料地区水文预报问题的常用方法有区划方法、单位线地区综合法、地貌瞬时单位线法和推理公式法等方法。本文针对区划方法,对无资料地区水文预报中的应用研究作了相关探讨。首先介绍了当今国际上区划方法在无资料地区水文预报工作中的研究现状,然后针对现存的问题,以及区划方法在无资料地区水文预报中的应用前景作出了相关阐述,为我国无资料地区的水文相关工作提供了可参考性建议,最后,本文结合当前国内和国际对无资料地区的水文预报研究相关工作总结,为我国无资料地区水文预报研究工作提出了未来的研究方向。
At present, the hydrological research in the unpolluted area has become one of the hot issues in the research on water environment of international hydrology. At present, there are some commonly used methods to solve the hydrological forecasting problem in the unpolluted area internationally, such as zoning method, comprehensive method of unit line area, instantaneous unit line method of geomorphology and reasoning formula method. In this paper, for the zoning method, the application of hydrological forecasting in non-material areas is discussed. Firstly, the current international research on zoning methods in hydrological forecasting in non-material areas is introduced. Then, the existing problems and the application prospect of zoning methods in hydrological forecasting in non-material areas are explained. Finally, this paper combines the current domestic and international research on hydrological forecasting in the non-material area, and puts forward the future research direction for the hydrological forecasting in the non-material area of our country.
