遥感水文耦合模型的研究进展

遥感水文的耦合模型在目前生态环境领域,特别是在水资源的应用和管理中其作用日益重要,具有大流域尺度上快速应用、实时动态监测等优点。结合国内外近年来取得的研究成果,文章综述了遥感水文耦合模型的研究进展。首先介绍了遥感技术在水文学中的应用,讨论了它的分类发展概况,接着介绍了几种主要的遥感水文耦合模型及其应用实例,包括SCS(SoilConservationServices)模型、SiB2(SimpleBiosphereModelversion2)简化生物圈模型、SRM(SnowmeltRunoffModel)融雪径流模型以及SWAT(SoilandWaterAssessmentTool)模型,最后展望了遥感水文耦合模型未来的发展趋势,指出尺度问题上的时空变异性仍是其发展的关键,与GIS(Geographicinformationsystem)及其他空间技术的相结合是其未来发展的重要方向,从而为水文学、水资源的预测评价等研究提供参考。

Advances in the coupled model of remote sensing and hydrology

Coupled models of remote sensing (RS) and hydrology, applicable to large scale watersheds in real-time with dynamic monitoring, play an important role in ecological and environmental investigations, especially in the management of water resources. This paper synopsizes the advances in the application of coupled models in recent RS and hydrological studies both at home and abroad. The paper starts by introducing the applications of RS technology in hydrology, divulging on its classification and development. Then it introduces major RS and hydrology coupled models, including SCS (Soil Conservation Services), SiB2 (Simple Biosphere Model version 2), SRM (Snowmelt Runoff Model) and SWAT (Soil and Water Assessment Tool). Finally, the intended development direction of the paper is presented, noting the crucial role of spatial and temporal variational scale problems, combinational methods of GIS (Geographic Information system) and other spatial analytical techniques. The findings of the paper would add to the existing body of knowledge on prediction and evaluation of water resources and hydrology.
