%X According to the water function, the section of the Yellow River in Gansu is divided into three series sectors, the water resource protection sector, the para-resource protection sector and the comprehensive functional sector. A new conception of planned water environmental capacity of each sector and a scheme for the control of total sewage discharge were proposed. Taking COD, the idicator of organic pollution, as an example, the author calculated the environmental capacities of the sedors based on the U. S. "PDM-PC model", which was simplied for the boundary condition to form an approximate analytic formula. The results thus reckoned from the formula and the planned environmental capacities are both continuous risk values of environmental capacities on the random conditions of different objectives and different probabilities. And these provide more choices for the overall control of sewage discharge and environmental policy-making.
