水文模型是认识水循环机理,进行水资源科学评价、合理利用的有效工具.迄今为止,国际上尚缺乏一个普适性强而易于应用的水文模型.本文基于自主研发的水文综合模拟系统(hydro-informatic modeling system,HIMS),面向不同应用,定制了小时、日、月等3个不同尺度的水文模型,并在洛河卢氏以上、泾河、无定河以及潮白河等流域取得了较为成功的应用.研究表明了HIMS系统的灵活性及较为广泛的适应性,有助于解决不同尺度的水文过程模拟难题.其基于遥感的区域尺度生态水文模拟功能也日益完善,有着较为广阔的应用前景.
Hydrological model is an essential tool for understanding the water cycle mechanism fully, evaluating and developing water resources rationally. So far, there is no universal and easy hydrological model at home and abroad. A hydrological model with three kinds of time scales and diverse function was developed in this study, based on Hydro-Informatics Modeling System (HIMS), a model developed independently. The model developed in this study was applied to simulate hydrological process in the Jing River basin, Wuding River basin, Chaobai River basin and the upper stream above Lushi of the Luo River. Besides, combined with Remote Sensing, water transport model based on soil-vegetation-atmosphere with regional scale and nutrient migration and transformation model were developed and applied to simulate the ecological water consumption of Sanmen Gorge of Yellow River and riparian degradation effect with N dimension of Guanting reservoir. The simulation achieved an expected result. So the study shows that the HIMS (including EcoHAT and HydroLib) has a universal adaptability and remarkable flexibility, and can contribute to simulate the hydrological process with different scales. At the same time, the eco-hydrological modeling of HIMS with regional scale based on Remote Sensing is increasingly improved.
