Abstract

The spatial distribution characteristics of copper in soil
of Lipu copper mining area was studied using geostatistics approaches combined
with GIS. The statistical analyses showed that a concentration of copper was
lognormal distribution. The Kriging interpolation maps reflected significant
spatial distribution of copper as influenced by both pollution and geological
factors. The present study indicated that GIS based geostatistics method could
accurately analyze the spatial variation of copper in the mining area. The content
of copper in the south was significantly higher than that in the north due to
paddy field land uses. In addition, the terrain of four terraces tilted to the
center and the broad irrigation accident occurred in the 4th trench in the south
of sampling area were also contributed to the higher concentrations of copper.
