摘　　要：为进一步查清安徽金寨富锌土壤资源分布及影响因素,基于金寨土地质量地球化学调查(1∶50000)成果,分析土壤Zn分布特征及影响因素。结果表明:土壤Zn含量最小值为18.4 mg/kg,最大值为474 mg/kg,平均值为77.9 mg/kg。圈定富锌土地面积1489.82 km^(2),占研究区面积的38.03%,主要分布在县域南部地区,Zn空间分布受土壤类型、土壤母质、土地利用方式、海拔及地质背景等影响显著,Zn含量与pH值、MnO、Fe_(2)O_(3)、有机质含量及海拔高度均呈正相关关系。研究成果为区内粮食安全生产、农业经济分区及富锌土地资源开发提供了科学支撑。In order to further investigate the distribution of zinc-rich soil resources and their influencing factors in Jinzhai County,Anhui Province,based on the results of the 1∶50,000 land quality geochemical survey of Jinzhai,the distribution characteristics of soil zinc(Zn)and the factors affecting it were analyzed.The results indicate that the minimum soil Zn content is 18.4 mg/kg,the maximum is 474 mg/kg,and the average content is 77.9 mg/kg.The area of zinc-rich soils was delineated as 1,489.82 km^(2),accounting for 38.03%of the study area,predominantly located in the southern part of the county.The spatial distribution of Zn is significantly influenced by soil type,soil parent material,land use,altitude,and geological background.Zinc content shows a positive correlation with pH,MnO,Fe_(2)O_(3),organic matter content,and altitude.The findings provide scientific support for food security production,agricultural economic zoning,and the development of zinc-rich land resources in the region.
