摘要
基于1∶5万土地质量地球化学调查采样分析获得土壤重金属元素和养分元素数据,对研究区进行土地质量地球化学分等。结果表明:(1)油山地区土地总体质量较好,以优质和良好为主;(2)油山地区圈定无公害富硒富锌土壤面积2651.08亩,无公害富硒土壤面积39317.67亩。农作物中水稻富硒概率较高,圈定3个以AA-A级绿色食品产地,建议当地可以优先开发绿色食品产地。
Based on 1:50000 land quality geochemical chemical survey sampling analysis of soil heavy metals and nutrient element data, the paper conducts geochemical grading of land quality in the study area. Results show that: 1) The overall quality of the land in Youshan area is good, with high quality and good quality. 2) The area of non-polluted Se-rich and Zinc-rich soil is2651.08 mu, and that of non-polluted Se-rich soil is 39317.67 mu. The probability of selenium-rich rice in crops is high, and three AA-A-level green food producing areas are delineated. It is recommended that local green food production areas be given priority.
