1. Topic analysis
Analyze the transmission characteristics of heavy metal pollutants, and establish a model to determine the location of the pollution source
In the third question, according to the spatial distribution map of heavy metal elements and the correlation between the elements, the propagation characteristics of the heavy metal elements are analyzed qualitatively and quantitatively. It is judged that the spatial distribution of metal elements is indeed point-source radial. The extreme points in the spatial distribution may be the pollution sources in the heavy metal transmission model, so we traverse the search, get the extreme points, and then filter in combination with the national soil environmental quality standards to find the main pollution sources of 8 heavy metal elements.
2. Transmission characteristics of heavy metal pollutants
We analyze the metal elements from the perspectives of qualitative and quantitative aspects, such as the path, mode and distribution pattern of propagation. As far as a single element is concerned, its propagation characteristics can be
