摘　　要：由于在利用原有方法进行镉污染地质生态修复监测时,受复合污染现象的影响而无法进行镉污染地质生态修复监测指标筛选,在土壤厚度为0 cm~20 cm的范围内,存在测得的镉活性数据偏差较大的问题,因此提出一种新的镉污染地质生态修复监测方法并对其进行效果评价。根据土壤内镉活性相关指标对镉污染地质生态修复监测指标进行筛选。随机在镉污染地质生态修复地区进行布点,并在布点处实施土壤镉污染地质生态修复采样。检测土壤镉污染地质生态修复样品,根据筛选的指标选取其对应的检测方法。Due to the influence of complex pollution phenomenon,it is impossible to screen the monitoring indicators of geological ecological restoration of cadmium pollution when the original method is used to monitor the geological ecological restoration of cadmium pollution.In the range of 0~20 cm soil thickness,there is a big deviation of measured cadmium activity data.Therefore,a new monitoring method of geological ecological restoration of cadmium pollution is proposed and its effect is carried out through evaluation.According to the related indicators of cadmium activity in soil,the monitoring indicators of geological ecological restoration of cadmium pollution were screened.The samples were randomly distributed in the cadmium contaminated geo ecological restoration area,and the soil cadmium contaminated geo ecological restoration sampling was carried out at the location.The corresponding detection methods were selected according to the selected indicators.
