| Abstract: | The advantage and shortcoming of using genetic algorithm(GA) to optimize parameter in pollution damage index assessment model was discussed.The paper present a linear regression optimized method for parameters of pollution damage index assessment model,which simplified the optimization process sharply and made practical application more convenient.After using this method to atmospheric quality assessment,the paper got a universal index formula of atmospheric environmental quality assessment,proved the feasibility of linear optimization eventually through compared assessment results of it with the GA optimization. |
