摘　　要：为优化环境改造方案有效性,设计新的重金属污染地区环境改造设计方案有效性评估方法。计算区域重金属容许最大负荷量,划分区域点源与非点源的输入输出特性,构建重金属污染地区环境改造设计方案有效性评估数学模型,通过指标结果判断环境改造方案的有效性。由实验结果可知:该评估模型的均值与标准差均小于现有模型,在评估效果测试中,该评估方法的准确性较高,该重金属污染地区环境改造设计方案的有效性评估方法较优,使用该方法可以得到更好的评估结果。In order to optimize the effectiveness of environmental transformation schemes,a new evaluation method for the effectiveness of environmental transformation schemes in heavy metal polluted areas was designed.The paper calculates the allowable maximum load of regional heavy metals,divides the input and output characteristics of regional point sources and non-point sources.It builds a mathematical model for evaluating the effectiveness of environmental transformation design scheme in heavy metal polluted areas,and judges the effectiveness of environmental transformation scheme through the index results.The experimental results show that the mean and standard deviation of the evaluation model are less than the existing models.In the evaluation effect test,the accuracy of the evaluation method is high,the effectiveness evaluation method of the environmental transformation design scheme in the heavy metal polluted area is better,and better evaluation results can be obtained by using this method.
