| 中文摘要: |
| 本文针对点源和面源污染进入水体的途径和季节不同，而水体纳污能力也是随季节动态变化的特点，从既能充分利用水体对污染物的稀释自净能力，又能保护环境等多重目的出发，提出了将90%保证率枯水期设计水文条件下计算得到的纳污能力的差额作为点源排放总量控制定额，而将90%保证率丰水期设计水文条件下计算得到的纳污能力减去枯水期纳污能力的差额作为面源总量控制定额。并以滇池为例进行了滇池点源与面源总量控制定额计算，为滇池水污染控制提供依据。 |
| 英文摘要: |
| The method for determining the allowable total amount of pollutant discharged into river is proposed. In view of the fact that the pollutant carrying capacity of water body changes with the seasons, it is suggested that the pollutant carrying capacity calculated for dry season with 90% guarantee frequency may be taken as the controlled amount of pollutant from point sources, and the capacity by subtracting this amount from the capacity for flood season with 90% guarantee frequency should be taken as the controlled amount of pollutant from non-point sources. The calculation for the Dianchi Lake, Yunnan Province, is given as the example for demonstration. |
