简要介绍了概念性降水—径流模型的多目标参数优选方法,以新安江模型为例,从Pareto支配法(Pareto Domination Approach)原理出发讨论了四目标函数情形下Pareto最优参数空间(Pareto Optimal Set)的Pareto优先排序(Pareto Preference Ordering)求解策略。通过对汉江上游江口流域降水—径流的新安江模型的模拟检验,证明该方法能够为模型提供全局最优参数,好于传统的单目标参数优选结果。
This paper briefly introduces the multi-objective parameter optimization method of conceptual precipitation-runoff model. Taking Xin’anjiang model as an example, the Pareto Optimal Set (Pareto Optimal Set) is discussed based on Pareto Domination Approach principle. ) Pareto Preference Ordering solution strategy. By simulating the Xinanjiang model of precipitation and runoff in the estuary of the upper reaches of the Hanjiang River, this method is proved to be able to provide the global optimal parameters for the model, which is better than the traditional one-target parameters.
