摘　　要：以安徽省潜山市全区表层土壤为研究对象,系统采集了8278件土壤样品,对土壤硒含量的分布特征及其主要影响因素进行了分析研究。结果表明:潜山市表层土壤硒含量整体偏低,平均值为0.184 mg/kg,全区表层土壤以足硒和潜在硒不足为主,两者面积占比为89.61%,硒不足土壤面积占比为5.41%,富硒土壤面积占比为4.98%,无硒中毒土壤。从空间分布来看,潜山市富硒土壤主要分布于槎水镇、水吼镇、官庄镇、天柱山镇和塔畈乡一带,具有一定富硒资源开发潜力。潜山市表层土壤硒含量受成土母质、土壤类型、土地利用方式等因素综合影响。潜山市富硒土壤主要分布于林地图斑,高背景值和有机质含量可能是土壤富硒的重要因素。In this study,a total of 8278 topsoil samples were collected from Qianshan City,Anhui Province to analyze the distribution characteristics and main influencing factors of selenium content in the soils,indicating a low soil selenium content in Qianshan City as a whole,0.184 mg/kg in average.The adequate selenium and potentially inadequate selenium dominate in the topsoil in the city,accounting for 89.61%in area,the inadequate selenium covers 5.41%,and rich selenium 4.98%,without selenium-poisoning soil.Selenium-rich soil mainly distributes in towns of Chaosui,Shuihou,Guanzhuang,Tianzhushan and Tafan,where there is potential for development of selenium-rich resources.The selenium content of topsoil in Qianshan City is affected by the parent material,soil type and land use.Selenium-rich soil mainly falls in forest map spots in Qianshan City,and high background level and organic matter content may be important factors for selenium-rich soil.
