摘　　要：分析山东省17个地市小麦-玉米轮作方式的耕层土壤样品的有效铁,结果表明:山东省农田土壤有效铁平均含量22.92 mg/kg,高于山东省土壤的平均水平,其变化范围为3.01～201.60 mg/kg;不同土壤类型土壤有效铁含量依次为棕壤>砂姜黑土>潮土>褐土;山东省不同地貌类型的土壤有效铁含量分布特点呈明显的区域性,表现为东高西低,中部的鲁中山区也有部分的高含量区分布。The paper analyzed the available Fe content in the wheat-maize rotational cropping soils in 17 cities of Shandong Province. Results showed that the average available Fe content in farmland soils of Shandong Province was 22.92 mg,/kg, above the average level in the soil of Shandong Province, which ranged from 3.01 -201.60 mg/kg; the content of available Fe in different soil types decreased in the order of brown soil 〉 Shajiang black soil 〉 fluvo-aquic soil 〉 cinnamon soil. The distribution of soil available Fe content was characterized by obvious regional features, it was high in the east and low in the west, high content of available Fe could also be found in some areas of Central Shandong Prov- ince.
