摘　　要：土壤中的重金属污染,尤其是镉的污染,对环境和人类健康构成了严重威胁。镉是一种非生物降解性污染物,可通过食物链累积并导致各种健康问题。为应对这一挑战,植物修复技术被广泛研究与应用,这些技术利用植物的自然能力去除、稳定或转化土壤中的重金属,但单独使用时往往效率不足。通过实验设计对比分析了单独植物修复与植物联合化学淋洗技术在去除土壤中重金属镉的效果。研究中采集了多个样本,通过设置不同的实验周期和监测指标。植物联合化学淋洗技术在提高镉去除效率和改善土壤质量方面表现优于传统单一植物修复方法,为土壤重金属污染的治理提供了更有效的技术方案。Heavy metal pollution in soil,especially cadmium pollution,poses a serious threat to the environment and human health.Cadmium is a non biodegradable pollutant that can accumulate through the food chain and cause various health problems.To address this challenge,plant remediation technologies have been widely researched and applied.These technologies utilize the natural abilities of plants to remove,stabilize,or transform heavy metals in soil,but their effi ciency is often insuffi cient when used alone.This article compares and analyzes the effectiveness of single plant remediation and plant combined chemical leaching technology in removing heavy metal cadmium from soil through experimental design.Multiple samples were collected in the study by setting different experimental periods and monitoring indicators.The plant combined chemical leaching technology performs better than traditional single plant remediation methods in improving cadmium removal efficiency and soil quality,providing a more effective technical solution for the treatment of heavy metal pollution in soil.
