基于地理信息系统的生态水文模型研究进展

Progress of ecological hydrological model based on geographic information system

在明确生态水文学及生态水文模型概念的基础上,重点阐述了基于GIS生态水文模型数据集优化的研究进展,探讨了目前基于GIS实现生态水文耦合相关研究存在的显著问题,即尺度转换、耦合点和耦合方法.并根据当前问题阐述未来生态水文模型发展方向,建立大尺度和适用广泛的生态水文模型将是下一步研究的重点.

On the basis of clarifying the concepts of ecological hydrology and ecological hydrological model,the research progress of GIS-based ecological hydrological model data set optimization is emphasized,and the significant problems existing in the related research of ecological and hydrological coupling based on GIS are discussed,namely scale conversion,coupling points and coupling methods.Aiming at the current problems,the future development direction of the eco-hydrological model is elaborated.The establishment of large-scale and widely applicable ecological hydrological models will be the focus of future research.
