The Distribution Characteristics of Metal Pollution Generated by Mineral Resource Exploitation——Illustrated by a Copper Mine Region in Yalong River Basin
Mineral resources exploitation could make heavy metal pollution on water and soil. This paper took a copper mine in Yalong river basin in Jiulong as study area. The trend of copper concentration,DEM,slope,Euclidean distance and accumulation were obtained by sampling and GIS,then the distribution characteristics of copper were concluded as follows. Stream had the ability of degradation and dilution,and thus copper content was enriched at upstream,which was in high terrain area and close to mine point. Howeve...
