Soil selenium content affects the absorption and accumulation of selenium in crops and ultimately affects human health; therefore, it is of great significance to study the characteristics of selenium content in soils and crops. Based on the previous agricultural geological survey and research carried out in Lintong area, and combined with data of Second National Land Survey, the agricultural geological survey and evaluation at the village level was carried out in Zhangba Village, Lintong District. Distribution characteristics of soil selenium content in each plot and selenium levels in crops were analyzed systemically, and the causes and influence factors of soil selenium was preliminarily studied. This survey found that selenium content of the soils and crops in Zhangba Village all met the standard of selenium enrichment. This finding provides strong support for land resource planning and management and rational utilization of selenium-rich soil resources in this area, moreover, it is of great significance to adjust planting structure, improve land use value, and promote development of selenium-rich agriculture.
