摘　　要：为建立适用于实际问题且精度较高的水质模拟模型,基于多参数最优化估值原理,以深圳市原水系统中的多个水库为例,建立了多参数最优化估值模型,并基于粒子群算法对多库水质联合模拟模型中的水质参数进行优化求解。计算结果表明,该模型求得的水质参数合理、可行,且模型计算精度可满足工程应用要求,为城市原水系统水量水质联合调控提供了参考依据。In order to establish water quality simulation model which is more accurate and applicable to the actual problems, the optimal principle of valuation for water quality multiple parameters is used to optimize the model parame ters. Taking multi-reservoirs of the raw water system in Shenzhen City for an example, a valuation model of multi-param eters optimization is established. In addition, based on the particle swarm algorithm, the parameters of the simulation model for water quality of multi-reservoirs are optimized. The calculation result shows that the water quality parameters obtained by this model is reasonable and feasible. Besides, the model accuracy can meet the engineering application requirements, which provides important reference basis for joint regulation of water quantity and quality of city raw water system.
