发布时间:2018-09-17 19:46
【摘要】:模型本身及其参数的不确定性使其模拟结果的可靠性备受争议,科学地认识模型的不确定性并对其进行定量的评价一直是环境模型研究的前沿,也是环境模型构建和应用过程中不可缺少的环节.通过敏感性分析,研究模型输入参数的变化对模型输出结果的影响程度,有助于了解并简化模型结构、提高参数率定效率、增进模型精度并增加模型应用的可靠性.本研究总结了敏感性分析在环境模型中的作用,并对常见的敏感性分析方法的原理、应用范围和优缺点进行了综述.最后,阐述了敏感性分析在环境模型模拟决策中应用的现状和未来研究方向.
[Abstract]:The uncertainty of the model itself and its parameters makes the reliability of the simulation results controversial. Scientific understanding of the uncertainty of the model and quantitative evaluation of it have always been the frontier of environmental model research. It is also an indispensable link in the construction and application of environmental models. Through sensitivity analysis, the influence of the model input parameters on the model output is studied, which is helpful to understand and simplify the model structure, improve the efficiency of parameter rate determination, improve the accuracy of the model and increase the reliability of the model application. This study summarizes the role of sensitivity analysis in environmental models, and summarizes the principles, applications, advantages and disadvantages of common sensitivity analysis methods. Finally, the present situation and future research direction of sensitivity analysis in environmental model simulation decision making are described.
