摘要
在最小二乘参数估计法的基础上,运用模糊数学的方法,研究水文模型与实测点的拟合度,经逐步回归拟合最终确定模型参数,并且给出了最大拟合度参数估计的计算方法。并用该方法对陕西省桃曲坡水库灌区的续建配套与节水改造规划进行了进一步的理论分析。
The hydrology model and its degrees of fittings are studied on the basis of the least square parameter estimation and fuzzy mathematics. The model parameter is determined by gradual regression fitting, and the way of calculation of the largest fitting parameter estimation is provided. This method is used to analyze the further construction and water saving transformation of Tao Qu Po Reservior drainage in Shaanxi.
