基于GLUE的土壤溶质运移参数反演及不确定性
质运移模型 参数反演 广义似然不确定性估计(GLUE)方法 不确定性分析
2018/11/5
溶质运移模型参数的识别结果常存在较高的不确定性,制约了模型的实际应用。以土壤中Cu2+运移过程为例,采用广义似然不确定性估计(Generalized likelihood uncertainty estimation, GLUE)并引入最大似然值(Maximum Nash-Sutcliffe,MNS)等三种定量指标,探讨了数值反演估计弥散系数等参数的不确定性。结果表明,非线性最小二乘法(Nonli...

利用GLUE方法不同算法分析TOPMODEL模型不确定性
不确定性 GLUE方法
2015/10/15
以丹江的西峡流域为研究对象,采用GLUE方法探讨TOPMODEL模型不确定性。分析不同似然函数算法、调节
参数、模型参数和结果预测区间的不确定性,结果表明不同算法的似然函数值既有差异又有相似性,值变化会引起不同
似然函数分布的变化,也影响模型参数与似然值的关系。分析不同阈值的90%置信区间的实测值覆盖率、预测区间宽度
及预测区间对称性等特征,结果说明阈值越小,预测区间的可靠性越高,但不确定性...
目前对水质模型进行参数率定通常利用计算机算法来实现,但由于水质模型日趋复杂的非线性结构往往会导致"异参同效"现象,无法通过单个似然度判断参数的取值是否能够取得真值.为避免这一情况,本文提出了一套基于GLUE法的多目标模型参数率定方法,并以WASP水质模型的应用为例,通过Sobol方法确定模型的敏感参数,并利用DO、CBOD、氨氮、硝态氮4项指标的似然函数对参数同时进行率定.结果表明,该方法既可以有...
