| 摘 要： | 利用白化权函数描述水质分级,利用平均标准值法进行量纲一化,利用倒数法确定聚类权,建立了大凌河水环境质量灰色评价模型.根据大凌河污染物排放特点选择参评因子,以地表水环境质量标准为评价依据,对大凌河进行水质评价与分析.结果表明:上窝堡的水质等级为Ⅲ级,污染程度为中度；朝阳与义县的水质等级为Ⅳ级,污染程度为重度；凌海的水质等级为V级,污染程度为严重；大凌河部分水域已经不能满足用水要求,需要采取措施控制污染物排放.

| Abstract: | The grey clustering method uses whitenization weight function to describe the water quality classification,uses average standards to get non-dimension data,and uses inverse method to determine the clustering weight.By using this method,the system of Daling River water quality evaluation is established.According to the pollutant emission characteristics,impact factors are selected,then Daling River's water quality is evaluated based on the environmental quality standards for surface water.The results indicat... |
