| 摘 要： | 针对综合水质模型参数众多，难以同时估算的特点，介绍了二种参数优化方法，分别为：基因法，罗森布瑞克法和单纯形法，在分析了每种方法特点的基础上，结合具体实例进行比较验证，最后提出先进行模型参数灵敏度分析，再选用基因法对灵敏度高的参数进行优选，将优选结果作为罗森布瑞克法和单纯形法初始值，并进一步优选的设计思路。

| Abstract: | Aiming at the characters of synthetic water quality model,involving many parameters and being difficult to evaluate them simultaneously,three parameter optimization methods are introduced,that is Genetic,Rosenbrock and Simplex.Based on analyzing the characteristic of each method,the comparison and validation among them are implemented.In the end,the design thought is put forward,that analyzing the sensitivity of the parameters firstly,choosing the Genetic to optimize the parameters whose sensitivity are high secondly,making the optimized result as the initial value of the Rosenbrock and Simplex method and doing the more optimized progress finally. |
