摘　　要：为研究消落带滑坡引发的土壤重金属污染,以秭归段的消落带为例,选取了五个具有代表性的区段,采集了土壤样品,并对其中Pb、Cu、Cr、Cd、Zn和Ni等重金属的含量进行了测定。实验结果表明,淹没区的重金属含量相较于库岸区和消落区,呈现出普遍偏高的趋势,特别是Zn和Cu的含量更为显著。而在库岸区,虽然Zn和Cu的污染也处于中污染水平,但相较于淹没区,其生态危害程度较低,说明该区域的生态系统对重金属污染的抵抗力较强。相对而言,消落区的重金属含量较低,生态危害最小。To study the soil heavy metal pollution caused by landslides in the subsidence zone,this paper takes the subsidence zone in Zigui section as an example.Taking five representative sections as the research object,soil samples were collected,and the content of heavy metals such as Pb,Cu,Cr,Cd,Zn,and Ni was measured.The experimental results show that the heavy metal content in the submerged area is generally higher than that in the reservoir bank area and the subsidence area,especially the content of Zn and Cu is more significant.In the reservoir bank area,although the pollution of Zn and Cu is also at a moderate level,the ecological hazard level is lower compared to the submerged area,indicating that the ecosystem in this area has a strong resistance to heavy metal pollution.The heavy metal content in the subsidence area is relatively low,and the ecological harm is minimal.
