摘　　要：本研究旨在综合评价滇中南华地区的土壤养分、土壤环境、土壤质量和绿色富硒富锗产地土壤环境质量。通过分析在滇中南华地区开展的1:250000土地质量地球化学调查工作获得的630份表层土壤样本数据,依据国家和行业相关标准对上述指标进行评价。结果显示,研究区土壤养分总体为中等—较丰富水平,一等、二等养分充足的土壤占37.19%,三等土壤占42.35%;土壤环境整体较好,一等土壤(无风险)占比达到80.19%,二等土壤(风险可控)占比为19.41%,三等土壤(风险较高)占比仅为0.40%;土壤质量综合等级总体为优质—良好水平,一等(优质)和二等(良好)土壤占比达到60.26%;达到AA级绿色富硒产地标准的土壤占比为2.78%,面积为63 km^(2);达到AA级绿色富锗产地标准的土壤占比为28.5%,面积为646 km^(2);达到AA级绿色富硒富锗产地标准的土壤占比为2.78%,面积为63 km^(2)。研究区土壤养分较为充足,土壤环境总体较好,具有发展绿色富硒富锗食品的广阔前景。本研究对在滇中地区建立绿色富硒富锗种植、养殖实验基地以及开发绿色富硒富锗农畜产品提供了科学依据,助力了南华地区生态农业建设、地方经济发展和乡村振兴事业,对滇中地区发展绿色农业和土地利用规划有一定的参考作用。The study aimed to master the soil nutrients,soil environment,soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua of central Yunnan.Based on the 630 surface soil samples data obtained from the 1:250000 land quality geochemical survey in Nanhua of central Yunnan,the soil nutrients,soil environment,soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua County were evaluated according to relevant national or industry standards.The results showed that soil nutrient content in the study area was medium-highly rich,with 37.19%of the soil having sufficient nutrients of the first and second grades,and 42.35%of the soil having sufficient nutrients of the third grade.The overall soil environment was good,with first-grade soil(risk-free)accounting for 80.19%,second-grade soil(risk-controllable)accounting for 19.41%,and third-grade soil(higher risk)accounting for only 0.40%.The comprehensive grade of soil quality was generally high-quality and good,and the proportion of first-grade(high-quality)and second-grade(good)soil reached 60.26%.The proportion of soil that meets the AA grade green selenium-rich production area standard was 2.78%,and the area was 63 km^(2).The proportion of soil that meets the AA grade green germanium-rich production area standard was 28.5%,and the area was 646 km^(2).The proportion of soil that meets the AA grade green selenium-rich germanium production area standard was 2.78%,and the area was 63 km^(2).The soil nutrients in the study area were relatively sufficient,the soil environment was generally good,and it had broad prospects for the development of green selenium-rich and germanium-rich foods.This study provided a scientific basis for the establishment of a green selenium-rich and germanium-rich planting and breeding experimental base and the development of green selenium-rich and germanium-rich agricultural and livestock products in central Yunnan,and contributed to the constru
