以空气质量扩散模式为载体,可以将影响空气质量的各种因素纳入到一个共同的体系中综合研究,进而揭示空气污染问题的本质特征和发展变化规律,为空气质量科学管理提供理论支持.科学地选取空气质量扩散模式是计算结果能够反映客观实际的前提,比较不同模式模拟结果的优劣是模式选取的主要依据之一.对空气质量模式的中的ISC3和CALPUFF模式的应用进行了比较,分析了模式模拟值与实测值差异,对于利用空气质量扩散模式寻求空气污染解决途径以及预测污染态势具有一定的实际意义和参考价值.%With the air quality diffusion model as the carrier, a variety of factors which affecting the air quality could be taken into a common system for the comprehensive study, and then the essential characteristics and development law of air pollution could be revealed, providing the theoretical support for scientific management on air quality. With scientific selection of the air quality diffusion models as the prerequisite, the calculated result could reflect objective reality, and comparison on the calculations of variety diffusion model was one of the main basis for model selection. This paper compares the application of ISC3 and CALPUFF of the air quality diffusion models were compared, and the differences between simulated and observed values were analyzed. This had certain practical significance and referential value for seeking the approach to air pollution and pollution situation forecast by air quality diffusion model.
