摘　　要：文章旨在探讨典型中小河流在突发重金属污染事件下的扩散特征。通过选定研究区域,进行采样与处理,并确立监测指标,系统分析了降雨径流条件下重金属污染的扩散特性。研究揭示了河流系统中重金属污染的扩散机理,并基于此构建了相应的污染扩散模型。结果表明,重金属污染在时间和空间上均呈现出特定的变化规律,对河流生态环境构成潜在威胁。不仅为理解中小河流重金属污染扩散提供了科学依据,也为相关治理措施的制定提供了理论支持。The purpose of this study is to explore the characteristics of sudden heavy metal pollution diffusion in typical small and medium-sized rivers.By selecting the study area,sampling and processing,and establishing the monitoring indicators,the diffusion characteristics of heavy metal pollution under rainfall runoff are systematically analyzed.This study reveals the diffusion mechanism of heavy metal pollution in the river system,and constructs the corresponding pollution diffusion model based on the analysis.The results show that heavy metal pollution presents a specific change law in time and space,which poses potential threat to the ecological environment of the river.This study not only provides a scientific basis for understanding the diffusion of heavy metal pollution in small and medium-sized rivers,but also provides theoretical support for the formulation of relevant pollution control measures.
