摘　　要：为实现大气环境质量预测和模拟,通过对大气污染和水体污染过程分析,从污染物迁移转化空间形式出发,构建了基本的环境流体力学三维模型,并针对某市大气污染物排放情况改进了迁移模型。运用Matlab软件,推算出各污染物达标需要的天数。该模型的优点是可以适用于研究各种污染物污染过程,预测某一时刻某位置污染物浓度。最后,进行成本比较,提出了环境治理策略。In order to forecast and simulate the quality of atmospheric environment, proceeding from the spatial form of pollutants transfer and conversion, the author constructs a basic three-dimensional model of environmental hydrodynamics by analysing the processes of atmos- phere and water pollution, and consequently improves the transfer model in light of the emission situation of air pollutants in a certain city. Through the use of Matlab software, the number of days needed for satisfying the standards with regard to each pollutant is calculated. The model has the advantage of being able to be applied to a variety of pollution process researches, and to predict the concentration of pollutants at a certain location and at the given moment. Finally, cost comparison is conducted, and the strategies for environmental problems are pro- posed.
