摘　　要：河道的最小控制流量和最大纳污控制量(简称“双总量”)是维系河流健康的决定性因子。论文初步建立了基于水资源合理配置的河流“双总量”控制研究技术框架,并对唐山市月尺度的“双总量”控制指标进行核算。通过水资源合理配置,除个别枯水年份和连续枯水年份外,唐山市河道的最小控制流量均可得到满足。在基准年、2010年和2020年3个规划水平年,唐山市规划河流COD的最大纳污控制量分别为16 357.57、12 659.19和11 572.50t/a;NH3-N的最大纳污控制量分别为907.80、660.27和580.09t/a。在统一水资源配置平台上制定的“双总量”控制指标,从根本上保障了竞争用水条件下河流生态需水,客观确立了规划水平年河道纳污能力的年内分配,并整体上提高了河流的最大纳污能力。Minimum controlling flux（MCF） and Maximum controlling pollutant load（MCP） （for short as ＂dual gross＂） are the key indexes for integrated regional water quality and quantity management and to sustain the ecological health of the rivers. The technical scheme for the dual gross control research has been erected primarily in this manuscript,and with such a scheme,the monthly dual gross control indexes have been derived.With the rational water resources allocation,the MCF in Tangshan can be complied except the low water year and continuous low water years.The maximum controlling COD load of rivers in Tangshan in the basic planning year,2010 and 2020 are 16 357.57t/a,12 659.19t/a and 11 572.50t/a,respectively,and the maximum controlling NH3-N are 907.80t/a,660.27t/a and 580.09t/a accordingly.With dual gross control indexes sustained by the unified water resources allocation platform,the eco-water requirement of rivers can be guaranteed under the condition of the water users competition;and the distribution of the pollutant carrying ability in a year can be derived subjectively ;at the same time, the MCP can be improved.
