摘　　要：为了全面掌握土壤质量现状,促进土地资源的科学合理利用和绿色生态农业可持续发展,实现生态功能最大化,以武安盆地为研究对象,在河北省平原区多目标区域地球化学调查(1∶25万)数据基础上,进行补充土地质量地球化学调查、取样和化验。采集和收集表层土壤样品分别为219、86件,系统分析武安盆地土壤样品中氮、磷、钾、锌、硒、铬、汞、有机质、pH值等30个项目的含量及分布规律,依据相关标准和规范综合评价土壤养分、环境、综合质量以及特色土地资源特征。评价结果显示,研究区土壤质量以一等、二等为主,占比分别为41.59%、52.94%,三等分布面积较小,占比仅为5.47%;特色富硒土壤面积66.76 km2,占比13.6%;特色富锌土壤面积123.36 km^(2),占比25.1%。研究区土壤养分总体中等,环境总体清洁,质量总体较好,特色富硒、锌土壤广泛分布,同时,土壤中富含多种对作物生长有益的元素,可为农业生产提供良好的基础条件。In order to fully grasp the current situation of soil quality,promote the scientific and ratio-nal utilization of land resources and the sustainable development of green ecological agriculture,and maxi-mize the ecological function,the Wuan Basin is taken as the research object,and based on the data of multi-objective regional geochemical survey(1∶250000)in Hebei plain region,supplementary land quality geochemical survey,sampling and laboratory testing were carried out.A total of 219 and 86 surface soil sam-ples were collected,respectively.The contents and distribution rules of 30 items including Nitrogen,Phos-phorus,Potassium,Zinc,Selenium,Chromium,Mercury,organic matter and pH value in soil samples from Wuan Basin are systematically analyzed,and soil nutrients,environment,comprehensive quality and characteristics of land resources are comprehensively evaluated according to relevant standards and norms.The evaluation results show that the primary and secondary soil quality in the study area are 41.59%and 52.94%,respectively,while the third-grade soil quality is small,accounting for only 5.47%.The character-istic Selenium-rich soil covers 66.76 km^(2),accounting for 13.6%,The area of characteristic Zinc-rich soil is 123.36 km2,accounting for 25.1%.The soil nutrients in the study area are generally medium,the soil envi-ronment is generally clean,and the soil quality is generally good.The characteristic Selenium-rich and Zinc-rich soils are widely distributed.At the same time,the soils are rich in a variety of elements beneficial to crop growth,which can provide good basic conditions for agricultural production.
