摘　　要：通过阐述硒在土壤中的含量和分布特点,了解不同土壤类型中硒含量的分布和差异,明确硒元素在土壤中的普遍迁移规律,重点总结了影响硒在土壤中生物有效性的因素,系统说明如何通过调控技术提高土壤中硒的生物有效性。对于探索生物地球化学循环中硒元素的迁移规律,提高土壤中硒的生物有效性提供参考。The content and distribution characteristics of selenium in soil were expounded,to understand the distribution and difference of selenium content in different soil types.The general migration law of selenium in soil was clarified and factors affecting the bioavailability of selenium in soil were summarized emphatically.And how to improve the bioavailability of selenium in soil through regulatory techniques was systematically elaberated.This study provides a reference for exploring the migration of selenium in biogeochemical cycles and improving the bioavailability of selenium in soil.
