| 摘 要： | 深入分析了分布式与半分布式水文模型的空间离散化方法,结合多种方法的优点对汉江流域下垫面信息进行离散化处理,既综合了子流域和地貌单元反映地形特征的优势,又引入"马赛克地块"面积分布函数,简单有效反映了不同植被覆盖影响.同时,为每个计算单元都进行了含有拓扑信息的编码,高效组织了众多空间数据,便于计算机自动处理,缩短计算时间.为构建分布式水文模型时尽可能全面反映下垫面空间异质性同时又尽可能少的引入参数打下了坚实基础.

| Abstract: | A new spatial discretization method for Hanjiang River Basin is proposed by combining the advantages of various previous methods.Not only integrated the advantages of sub-basins and geomorphologic units reflecting topographical features,but introduced the "mosaic block" area distribution function impacting different vegetation cover.Meanwhile,each calculated unit is endued with topology information coding,which efficiently organized a large number of spatial data to facilitate automatic processing and reduc... |
