- Abstract:
-
Lao wanchang Lateritic gold deposit in Guizhou is a kind of karst-collapse-originated Lateritic gold.The perennial and devastating mining leads to a mass of limestone exposing to the earth’s surface and becoming a new rock desertification.On the dry environment area,bryophytes have become the main soil crust plants.In order to explore the characteristic of soil crust bryophytes on gold deposit,we studied the bryophytes of limestone and lateritic gold sites in Lao Wanchang Lateritic Gold Deposit of Qinglong in Guizhou in August,2007.Based on the extensive investigation and identify of the bryophyte specimens,35 species in 23 genera of 10 families were found.There were no Hepaticae in this two area.There were16 species belonging to 11 genera of 5 families on limestone,26 species belonging to 20 genera of 5 families on lateritic gold sites.On limestone and lateritic gold sites,there were 6 same genera and 7 same mosses.The species of Pottiaceae were the main soil crust bryophytes in this two area.The similarity coefficient of genera and species are quite low.The bryophyte communities of the soil crust on limestone are pure communities while those on lateritic gold sites are mixed.
