Abstract 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.

Key words Bio-availability;Regulation technique;Selenium
