Abstract: The definition and classification of water environmental capacity were standardized, the river water environmental capacity models, water resources and water environmental condition in Shandong Province were established according to the characteristics of hydrology. The computational procedures and methods for water environmental capacity adapted to rivers in north China were constructed, and the corresponding relation among the water functional zone, the discharge inlets to the river and point source discharge outlets were found. The estimation method for converting the water environmental capacity in waters into the maximal permitted discharge amount on land was put forward. The water environmental capacity and maximal permitted discharge amount meeting the condition of the water functional zone were calculated for 239 rivers and 547 water functional zones in Shandong Province, and thus the total amount control scheme of water pollutants was provided with a scientific basis.
