Abstract—The capacity total control, in the field of water
pollution prevent, is more effective than the traditional
mandatory total control. In this article, GIS was applied into the
capacity total control of water pollutant. Using the ArcSDE
technology, a spatial geodatabase that included many kinds of
spatial information and attribute data was built. Based on it, a
spatial model system of the water pollutant capacity total control
(WPCTC) under GIS was developed by the redevelopment in
Delphi, VBA and ArcGIS environment. By applying many types
of GIS functions, such as buffer analyzing, linear referencing and
spatial distance measuring etc, this model system could greatly
increase the efficiency and precision of the total control, and had
the characteristic of visibility.
