【摘要】:为定性了解不同洪水频率下汇流参数m,平均比降J两个参数对推理公式法进行无资料地区产流模拟的影响,利用LH-OAT全局敏感度分析方法对推理公式法进行参数敏感性分析。以两个不同分区的小流域(山西省方山县圪洞沟和孝义市下堡河流域)汇流为例,研究确定不同洪水频率下推理公式法参数的敏感性,确定参数敏感程度和变化规律,为模型参数率定提供数值参考。研究表明,推理公式法参数对洪峰值敏感性排序为mJ;m和J的敏感性随着洪水频率的减小呈现减弱趋势,两个参数随洪水频率变化的速率为V_mV_J。
[Abstract]:In order to find out qualitatively the influence of two parameters, I. e., the confluence parameter m and the average ratio drop J under different flood frequency, on the simulation of runoff production in non-data area by the method of inference formula, The LH-OAT global sensitivity analysis method is used to analyze the parameter sensitivity of the reasoning formula method. Taking the confluence of two small watersheds (Gedonggou, Fangshan County, Shanxi Province and Xiapu River Basin, Xiaoyi City) as an example, the sensitivity of reasoning formula parameters under different flood frequencies is studied, and the sensitivity and variation of parameters are determined. It provides a numerical reference for the determination of the model parameter rate. The results show that the sensitivity of mJ;m and J to the flood peak sensitivity of the inferential formula method decreases with the decrease of flood frequency, and the variation rate of the two parameters with flood frequency is VmVJJ.
