模糊数学法在大气环境质量评价中的应用方法探讨

环境质量评价是环境科学的重要组成部分。影响环境质量的因素很多,如何选择合理的模型并充分地利用有限的监测信息,客观地描述环境质量优劣状况,为环境整体规划及环境污染防治提供依据,是环境质量评价的基本任务。文章通过具体实例介绍了模糊数学法在大气环境质量评价中的应用,并根据大气污染因子的复杂性,采用超标法赋权并归一化,按最大隶属原则,通过模糊数学模型对实例中某城区大气环境质量进行了单因子评定及综合评定。

Application of the fuzzy math method to atmosphere quality evaluation

Evaluation of environment quality plays an important role in environment science. As a great many of factors affect the environmental quality,it is a basic task to select a rational valid pattern and make full use of limited information from monitors so as to describe the environment quality objectively and provide a basis for general environment planning and preventive treatment of environment pollution. In this paper,a fuzzy math method is applied to evaluating the quality of atmosphere,and according to the principle of maximum membership grade,the atmosphere quality of a certain city is evaluated by using the fuzzy math model. Both single factor evaluation and multi-factor comprehensive evaluation are carried out.
