【摘要】 随着现代工业的不断发展，城市环境问题日趋严重。直接影响人们的生存环境，影响经济、社会、环境的协调发展。大气环境污染，已经成为人们倍受关注的城市环境污染问题之一。为了有效地冶理大气环境污染，首先须对大气环境质量作出科学评价。这对客观认识城市大气污染现状，预测其发展趋势，并有效地进行大气污染控制，实施可持续发展战略具有重要意义。 本文在收集武汉市大气监测数据及有关资料(如气候、地理、功能区的规划等)和分析研究大气环境质量评价方法的基础上，针对大气环境的多耦合性与复杂动态性，并考虑到环境质量评价中评价主体、监测资料、评价标准及环境要素的不确定性，提出用运模糊数学综合评判的方法进行大气环境质量评价。本办法通过确定大气污染评价因子和其评价等级的界定，建立降半梯形隶属函数，运用超标倍数加权法计算权重并进行归一化处理，建立起加权平均型武汉市大气环境质量评价数学模型。又进一步引入了数据库和C什语言计算机程序便于数据接口，避免了繁琐的人工计算。 结果表明：此模型不仅注意到分级界限的模糊性，而且在信息利用率和判别精度上和别的评价方法相比有很大优势。该方法科学、简便、精确、所得结果与武汉市大气环境质量现状相符合，具有较强的实际应用价值。更多还原

【Abstract】 With the development of modern industry, the environment of city becomes more and more serious. It directly affects the environment of people’s life and the development among economy, society and environment. The air pollution is one question of environment in city, and is motioned by more and more people. In order to efficiently control of air pollution, we should make scientific assessment to air quality. So the research for it is very important which we objective and accurate study the current situation of air pollution in city and predict the development trend, also efficiently control of the air pollution to make the strategy of the sustainable development.Based on collecting the air quality dates for weather, geography, the arrangement of city and studying the method on atmospheric environment quality assessment, the Paper assesses the atmosphere environmental quality with the method of fuzzy comprehensive judgement. Considering that environmental system is complicate, changeable and multiplefactor affacted, on the basis of the fuzzy machematies principles, stipulates assessment grade, this paper discusses how to establish judging method Standard and factors, sets up falling trapezoid subordinate function for the system and rati of the environmental factors by the method of over standard with weight. The weighting average mathematics model is founded. Dada base and computer procedure is also introduced into this model by C++ language, which offers the judgment access to Database and avoids troublesome Calculating by manpower.The result prove: This model not only considers the fuzziness of classification limit but also has better strenght on enhances the precision and utilization radio of information than other method. Therefore , the method is scientific simple, accurate. It is successful applied to analyze and evaluate the atmosphere environment quality in rent years of Wuhan city, The conclusion is close to the reality.更多还原
