摘　　要：在对欧式距离模型进行优化的基础上,根据不同评价指标对矿山生态环境影响程度的不同,得出评价指标的权重,以环境指标为轴,以Ⅰ等级环境质量水平为原点,结合不同因子权重求出待评价对象的变权欧氏距离。通过对某金属矿山生态环境进行监测,用变权欧氏距离方法建立评价模型,可知月恢复治理/破坏土地面积这一指标对环境影响最大,并得出了环境质量等级以及具体细化数值。与其他评价方法相比,变权欧氏距离可以得出矿山生态环境质量等级和具体等级数值,能够精确地反映出矿山生态环境质量水平。Based on the optimization of euclidean distance model,the weights of evaluation indexes were obtained,according to the different influence degree of the evaluation index to ecological environment of mines. The paper set environmental index as the axis,environmental quality level as origin,obtained the weighted Euclidean distance of the evaluation object combined with the weight of different factors. Through the monitoring of the metal mine ecological environment,an evaluation model was established by using the Euclidean distance method,which determined the ratio of recovery area and damage area every month as the index that had the largest impact on the environment,and proposed environmental quality grade and the detailed number. Compared with other evaluation methods,variable weighted Euclidean distance could not only draw the level of ecological environment quality of mine,but get the specific rating,and reflected the ecological environment quality level of mine accurately.
