Abstract

The invention discloses a quantitative research method for changes of heavy metals in soil around a mining area along with natural factors. Soil heavy metals in a China typical non-ferrous metal mining area buffer area range are used as research objects; the spatial statistics method is adopted, the distribution characteristics and migration rules of a series of natural factors of mining area soilheavy metals along with terrains (altitude and gradient), wind directions and rivers are analyzed; then discussion is conducted on arrangement of sampling lines, the change rule of heavy metal at thehigh altitude and the difference between upwind and downwind directions and upwind direction heavy metal concentrations, and a research result provides a scientific basis for comprehensive prevention, control and remediation of heavy metal pollution of surrounding soil.

Description

technical field [0001] The invention relates to the technical field of soil heavy metal detection, in particular to a quantitative research method for the change of soil heavy metals around mining areas with natural factors. Background technique [0002] Heavy metals in soil are persistent, difficult to decompose, easy to accumulate and highly toxic, posing a threat to nature and humans. Nowadays, the soil around the mining area is suffering from serious heavy metal pollution. Accurately grasping the distribution characteristics of heavy metals in the soil around the mining area is the premise of preventing and controlling soil heavy metal pollution. [0003] At present, domestic and foreign studies on the distribution of heavy metals in the soil around the mining area mainly focus on two aspects. On the one hand, it is to compare the statistical characteristics of heavy metal content in soil in different areas around the mining area, and to judge the distribution of heavy m...
