Abstract Aimed at tackling the stochastic variations caused by non-artificial natural factors and accidental factors such as nonpoint source contamination and point source contamination in geochemical maps for different continental and sea media of eastern Zhejiang coastal area, this paper puts forward a geochemical map formation method for different continental and sea media based on a suitable data-processing model and color area spatial distribution so as to improve the map face effects.
