摘要:
分布式水文模型相对与集总式水文模型,以其具有明确物理意义的参数结构和对空间分异性的全面反映,能更好地模拟真实的降水径流形成等水文过程.将区域尺度上的土壤水力侵蚀过程视为水文循环的一部分,基于对水土流失过程分析,考虑尺度问题的影响,对其中部分环节进行概化,借鉴前人对区域土壤侵蚀问题因子研究的成果,分析总结了建立基于GIS的区域尺度上分布式水蚀过程模型需要的参数,并讨论了参数的入选原则及其在模型中的应用方式.
Abstract:
Distributed hydrological model can reflect the real hydrological processes,such as the process from raining to surface runoff,because of its physical significance of the parameters and its fine representation of the special difference.The soil erosion by water is viewed as a part of hydrological circle here.Based on the studies of factors on soil erosion on a regional scale,and the analysis and the summarizing to the process,and the study of scales,the parameters needed in the distributed model of soil erosion prediction on a regional scale were given.Also the fundamental of parameters choosing and the application of the parameters in the model were discussed.
