Water environmental information data has spatial and temporal characters.The storage and visualization expression of spatial-temporal data have important methodological significance for describing the changes of the objective substances and assistant decision-making.Dynamic segmentation technology is a kind of linear reference model,which can accurately describe the linear elements such as rivers.Based on GIS platform,the dynamic segmentation technology and water environment model were integrated to construct the spatial-temporal data structure of water environment.And the visualization expression and time-series analysis of water environment spatial-temporal data were realized.The level of water environment assistant decision-making was enhanced.
