摘要
为了探索建立生态环境质量评价的方法,尝试运用物元可拓的方法来建立生态环境质量评价模型,通过构造物元矩阵,运用两种方法计算权值,再根据计算出的关联度值大小对大气环境质量进行可拓识别。通过用该方法对城市大气环境质量评价实例分析表明,不同的权值计算法计算出的结果对最终的物元可拓识别的影响很大,但证明了在大气环境质量评价中合理的应用物元可拓的方法是切实可行的。
In order to study a new evaluation method of atmospheric environment quality, the model of atmospheric environment quality evaluation is established with the method of matter-element extension. The weight value is calculated with two method through matter-element matrix, and the atmospheric environment quality is evaluated according to associated degree calculated. The analysis of atmospheric environment quality for a city shows that the weight value has an important effecting in matter-element extension evaluation, but the application of matter-element extension method in evaluation of atmospheric environment quality is feasible.
