| 中文摘要: |
| 为促进正安县76541 km2富硒耕地分区利用进行富硒特色农作物种植，通过统计分析7 433件表层土壤、灌溉水、大气干湿沉降物、农产品及其根系土壤、成土母岩等介质样品的测试结果，从空间分布、成土母岩耕地土壤、不同土壤类型、不同土地利用等条件下分析正安县土壤硒含量地球化学特征，运用叠图法进行富硒耕地利用分区划分。研究结果认为正安县富硒耕地质量总体良好，再结合绿色安全耕地质量标准进行利用分区研究，划分出富硒农产品首期推广区、富硒耕地优选开发区等两种类型区共27个区块，分别提出利用方向和针对性科学建设措施。结合贵州省2025年乡村振兴工作部署中乡村特色优势产业发展要求从农业地质角度为正安县富硒特色农业产业发展提供科学依据，最终促进农民增收。 |

| In order to promote the zoning and utilization of 76541km2 selenium rich farmland in Zheng’an County for the cultivation of selenium rich characteristic crops， the test results of 7433 samples of surface soil， irrigation water， atmospheric dry and wet sediments， agricultural products and their root soil， parent rock and other media were statistically analyzedThe geochemical characteristics of soil selenium content in Zheng’an County were analyzed under spatial distribution， parent rock farmland soil， different soil types， and different land usesThe stacked graph method was used to divide the utilization zoning of selenium rich farmlandThe research results indicate that the overall quality of selenium rich cultivated land in Zheng’an County is goodBased on the green and safe cultivated land quality standards， a zoning study was conducted to divide the land into three types:the initial promotion area for selenium rich agricultural products， the preferred development area for selenium rich cultivated land， and the area for suggested restoration or industrial structure adjustment， totaling 27 blocksThe utilization direction and targeted scientific construction measures were proposed respectivelyTo provide scientific basis for the development of selenium rich characteristic agricultural industry in Zheng’an County from the perspective of agricultural geology， in accordance with the requirements for the development of rural characteristic advantageous industries in Guizhou Province’s 2025 rural revitalization work deployment， and ultimately promote farmers’ income increase |
