Research on the diversity and impact factors of arbuscular mycorrhizal fungus in typical mercury mining area

The study goals is to (1) determine the arbuscular mycorrhizal fungus(AMF) spatial diversity in Wanshan Hg mine; (2) compare spatial difference of AMF community structure from different Hg content area; (3) evaluate the correlation between soil Hg content and AMF community structure; (4) screen the dominant strains of AMF for the application of AMF in the ecological restoration of mercury mining area.
