Abstract

In this paper, a method that integrates 3D GIS visualization, spatial statistical analysis, spatial database, environmental management & evaluation model for evaluating soil heavy metals pollution is presented. Based on the above method and strategies, taking the nearby farmland in the LongJiao hill mine district of Daye City in the Hubei province as an example, we found that the results using integrative method is superior to traditional method. With the technology of DTM and 3D visualization, the quantity of two heavy metals (Cu,Cd) in investigated six kinds of heavy metals (As, Cr, Pb, Cu, Zn, Cd) was easily found that exceeds the soil environment quality standard GB15618-1995. The research discovers the new idea and method can improve the efficiency and precision comparing to traditional heavy metals investigation and evaluation method. Different with traditional 2D representation mode, the new method integrated 3D visualization can visually represent and adequately evaluate soil heavy metals pollution distribution situation in the mineral area.
