摘要
本文阐述了基于SWAT模型构建克兰河流域上游空间数据库与属性数据库的过程。结合研究区DEM,将土地利用、土壤类型重新编码和细化,构建了空间数据库,用SPAW软件计算模型参数,建立了土壤物理属性数据库,运用SWAT模型中的"天气发生器"模拟日太阳辐射,为分布式水文模型建立和应用提供了数据基础。
This paper expounds the process of constructing spatial database and attribute database of upper reaches of Kelan River Basin based on SWAT model.combined with the study area DEM,the land use,soil types were re-coded and refined,a spatial database was constructed,model parameters were calculated by SPAW software,soil physical properties database was established,and the"weather generator"in the SWAT model was used to simulate provided a data basis for the establishment and application of distributed hydrological model.
