Soil sampling point laying method and system based on occurrence environment similarity

The invention discloses a soil sampling point laying method and system based on occurrence environment similarity, and relates to the technical field of soil environment monitoring, and the method comprises the steps: firstly obtaining to-be-selected sampling points, and determining main environment factors affecting soil occurrence in a target area; based on the main environment factors, constructing an occurrence environment feature vector of each to-be-selected sampling point, calculating a distance between the occurrence environment feature vectors of the to-be-selected sampling points, and calculating an occurrence environment similarity between the to-be-selected sampling points; taking other to-be-selected sampling points of which the similarity is greater than a preset threshold value as a representative domain of each to-be-selected sampling point; and determining a final sampling point based on the representative domain of each sampling point to be selected. According to the method, the representati
