煤矿城市大气质量评价的变权识别模型的建立及应用研究

利用煤矿城市各评价单元中大气评价因子的污染贡献率确定相应各个因子在各评价单元中的权重,充分体现不同单元内部相同因子之间的客观各异性;实现对属性识别理论模型的改进,建立变权识别模型;建立在有序分割和属性识别准则的功能基础之上的变权识别理论模型信息利用率高,能进行点位排序,划分出更细微的污染程度差别.最后对辽宁阜新矿业城市进行大气质量评价,将所得结果与综合指数法计算结果进行比较分析,给出变权识别模型的适用度,效果良好.

THE ESTABLISHMENT AND APPLICATION OF IDENTIFICATION MODEL WITH VARYING WEIGHT FOR AIR QUALITY EVALUATION OF COAL MINING CITY

In this paper, the weight of each evaluation gene of the coal mining city is determined by the pollution rates of them in order to establish a new concept called identification model with varying w eight. With standard data, relatively objective rules of classification respectively for units which are to be evaluated are founded. The new model which is based on order dividing and identification theory has the function of distinguishing little difference between the genes. And the work to determine the applicability of this model mentioned above is finished after the application of this model to air quality of coal mining city and then the comparison of results deduced from this model and comprehensive index. The result of analysis shows the new model is available.
