Control Unit Zoning for Liaohe River Basin in Liaoning Province Based on GIS

Abstract:

Control units are the management districts for water environment management on river basin. The control unit zoning is the necessary process relating the watershed management to pollution discharge reducing. Control units for Liaohe river basin in Liaoning province were zoned and adjusted based on GIS technology. The control units were suggested to be classified into 5 first level control units, 56 secondary level control units and 97 third level control units. Meanwhile, the information system of control units for Liaohe river basin in Liaoning Province was designed and developed with GIS component technology, which could provide the decision support on the information management of control units, the protection of water resources, total amount control of pollutant, and scientific planning of water environment management for Liaohe river basin in Liaoning Province.
