An Evaluation and Control Measures of Heavy Metal Pollution in Farmland Soil
This study focuses on the evaluation methods and control measures of heavy metal pollution in farmland soil.Using the grid method to collect farmland soil samples and perform preprocessing,the physical and chemical parameters of the soil samples are measured,yielding the results of heavy metal content.The study establishes a semivariogram model to analyze the spatial characteristics of farmland soil,calculating the heavy metal pollution index to obtain the evaluation results of the degree of heavy metal pollution in farmland soil.The study proposes a combination of biological,physical,and chemical control measures.Comparing the results with the standards for heavy metal pollution in farmland soil,it can be seen that the pollution level in the study area ranges from moderate to severe,highly consistent with the actual heavy metal pollution results in farmland soil.The assessment results for heavy metal pollution in farmland soil are highly accurate.Accordingly,corresponding control measures can be implemented to effectively protect and restore farmland soil,which has significant potential for promotion.
