基于组合模型的城市空气质量评价优化法

City Atmospheric Quality Optimal Assessment Based on Combined Model

摘要: 本文提出一种新的空气质量评价方法，即应用组合原理，以拟合优度法确定权重组合三个模型(API法，云模型及粒子群投影寻踪法)，并将之应用于香港空气质量评价中，实例表明该方法增加了评价性能，具有较强的可靠性和全面性，为城市空气质量综合评价方法提供了一种新思路。

Abstract: This paper puts forward a new atmospheric quality assessment method that is, according to the combinatorial theories, using Goodness of Fit method to get weights to combine three models which are air pollution index method, cloud model and Projection Pursuit Grade method. The combined model is applied to the Hong Kong atmospheric qual-ity assessment; the results show the method increases the evaluation performance, possesses more reliability and com-prehension, and provides a new idea for the city atmospheric quality synthetically assessment.
