摘要：
In order to reveal the mercury (Hg) emission and exchange characteristics at the soil-air interface under different vegetation cover types, the evergreen broad-leaf forest, shrub forest, grass, and bare lands of Simian Mountain National Nature Reserve were selected as the sampling sites. The gaseous elementary mercury (GEM) fluxes at the soil-air interface under the four vegetation covers were continuously monitored for two years, and the effect of temperature and solar radiation on GEM fluxes were also investigated. Results showed that the GEM fluxes at the soil-air interface under different vegetation cover types had significant difference (p < 0.05). The bare land had the maximum GEM flux (15.32 +/- 10.44 ng
