摘要
通过科学规划采样点位,系统采集工业区土壤样本,深入分析土壤pH值及不同地层重金属含量变化规律,揭示污染扩散特征。针对分析结果,提出了一系列修复策略,包括回填表土以改善土壤结构、应用植被修复技术促进重金属吸收与固定、实施土壤基质改良以调节土壤环境。实践表明,这些修复技术的综合应用,不仅有效改善了土壤pH值,还显著降低了土壤中重金属的含量,为工业区土壤修复提供了科学依据与技术支撑。
By scientifically planning sampling points and systematically collecting soil samples from industrial areas,the changes in soil pH and heavy metal content in different strata are analyzed in depth,revealing the characteristics of pollution diffusion.A series of remediation strategies were proposed based on the analysis results,including backfilling topsoil to improve soil structures,applying vegetation remediation techniques to promote heavy metal absorption and fixation,and implementing soil matrix improvement to regulate soil environment.Practice has shown that the comprehensive application of these remediation technologies not only effectively optimizes soil pH value,but also significantly reduces the content of heavy metals in soil,providing scientific basis and technical support for soil remediation in industrial areas.
