The Distribution Characteristics of Metal Pollution Generated by Mineral Resource Exploitation-Illustrated by a Copper Mine Region in Yalong River Basin
摘要
Abstract
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 con-centration, 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 abili-ty of degradation and dilution, and thus copper content was enriched at upstream, which was in high terrain area and close to mine point.However, the Cu content in soil was enriched at down-stream, which was in low terrain area and gentle slope.According to these rules, it was easier to e-valuate the pollution degree of other similar mining area with fewer but more pointed data.Mean-while, it also provided rational decision-making basis for mineral resource exploitation.关键词
