SIMULATED ANNEALING AND KRIGING METHOD FOR IDENTIFYING THE SPATIAL PATTERNS AND VARIABILITY OF SOIL HEAVY METAL

摘要

Environmental data, including information regarding soil heavymetals, may contain significant uncertainty and exhibit a skeweddistribution with a complex and unexplainable spatial variation. Thisstudy identified the spatial patterns and variations of soil heavymetals(Cu, Cd, Hg, and Pb)in the northern part of Changhua County inTaiwan to clarity the characteristics and pollution of soil Heavymetals. The spatial maps of soil heavy metals were also estimated andSimulated using kriging and simulated annealing methods.
