Regional pollution assessment method and system as well as insulator pollution degree assessment method and system

The invention relates to a regional pollution assessment method and system as well as an insulator pollution degree assessment method and system. A sampling point-based regional pollution assessment method comprises the steps of obtaining the concentration of each pollutant at a sampling point and the concentration of each pollutant at each value assessment point based on the sampling point; and calculating a pollution degree of each value assessment point according to a pollution degree of the sampling point, the concentration of each pollutant at the sampling point and the concentration of each pollutant at the value assessment point. According to the methods and systems, the influence of the pollutant concentration in a background environment on the pollution degrees of the sampling point and the value assessment point is effectively considered, so that accurate regional pollution assessment is realized while the pollution degree manual sampling work is reduced; and the sampling point-based regional pollut
