摘　　要：以淄博市博山区土地质量调查工作为基础,研究了该区硒的地球化学特征,探讨了土壤富硒来源和影响因素。研究发现:博山区土壤中硒的背景含量远高于全国土壤背景值,达到0.43 mg·kg^(-1);研究区50.09%的土壤处于足硒状态,42.89%的土壤处于富硒状态,富硒土地资源丰富。土壤硒含量的分布受成土母质、土壤类型和有机质等影响明显,主要受成土母质控制,具有明显的继承性;广泛出露的富硒岩层(特别是煤矿层)是影响土壤含硒量高低的主要因素。Based on the land quality survey in Boshan District,Zibo City,the geochemical characteristics of selenium in this area were studied,and the sources and influencing factors of selenium in soil were discussed.The results showed that the background content of selenium in Boshan soil was much higher than the national background value,reaching 0.43 mg·kg^(-1).50.09%of the soil in the study area is total selenium,42.89%of the soil in the state of selenium,rich land resources.The distribution of selenium content in soil was influenced by soil parent material,soil type,and organic matter and was mainly controlled by soil parent material with apparent inheritance.Widely exposed selenium-rich strata(especially coal mine strata)are the main factors affecting the level of selenium content in the soil.
