摘要
为反映和描述流域下垫面各个因子空间分布不均匀性和人类活动的影响,开发和建立小流域产汇流分布式模型。将流域划分为一系列的网格单元,可以计算出流域内每一网格单元上的径流过程,本模型在黑草河小流域上进行了率定和验证,模拟的降雨径流过程与实测洪水过程符合良好。
A distributed model for simulating runoff yield in small watershed is developed.The complicated influences of the underlying layer and human activities on runoff yield are taken into account.The simulated area is divided into regular cells and the generation process of the runoff in each cell can be calculated.Temporal and space variation of the watershed is reflected by the contributed characteristic of the cells.The model is calibrated and verified by the observation data of the Heicao River watershed.
