Design of Technology Platform Architecture of the Basin Water-quality Target Management Based on Service GIS

Aiming at the integrated technologies of basin water-quality target management and GIS, comparing the advantages and disadvantages between the traditional modes and service GIS model, the hierarchical structure, general architecture and building steps of a GIS-based basin water-quality target management technology platform were proposed. According to the construction demand analysis, detailed architecture of water-quality target management technology platform in the Liaohe River basin was established.
