Evaluation method for heavy metal pollution control effect in rural areas of northern Anhui Province

Abstract

AbstractSoil is an important part of human survival, and people's lives cannot be separated from soil. At present, soil pollution in China is becoming more and more serious, especially heavy metal pollution. Based on this, a method for evaluating the effect of heavy metal pollution treatment in rural areas in northern Anhui was proposed. Taking Liulangguan Lane, Nanling, and Dapu in the south of Anhui Province as the study area, the PLSR model was used to collect soil heavy metal content in the area as sample data. The fuzzy comprehensive evaluation method was used to analyze the effect of heavy metal pollution control in rural areas. The results show that most of the soil quality evaluation grades are grades 2 and 3 and need to be retreated. And the evaluation accuracy of the method is always greater than 0.9500, and the evaluation results are more credible.
