摘要： 为建立山东省临沂市沂蒙山区特殊地质背景土壤质量评价方法，在沂南县西南部研究区采集各类土壤样品1 029件，均分析了N、P、K、Mn、B、Mo、Cu、Zn、Co、V、Ni、Sr、Tl、Ti、As、Cd、Hg、Pb、Cr、Se、F、I、Ge、有机质、Na2O、SiO2、MgO、CaO质量分数及pH等29项指标。根据分析测试结果，建立了由土壤养分指标和环境指标组成的评价体系，并对该区土壤质量地球化学评价及其空间分布进行了研究。结果表明：研究区大部分土壤质量以良好、中等为主（土壤环境清洁，土壤养分丰富或中等）；研究区中部地区土壤肥力较好（w（N）>0.10%，w（P）>0.06%，w（K）>2.50%），西南部、东北部山区土壤肥力较差（w（N）<0.075%），土壤质量等级偏低。全区80%左右土壤的N元素、B元素、有机质均不足以满足常规农业生产需要，对常规作物生长不利。区内土壤环境质量水平总体较好，重金属元素分布受地质背景控制。
