摘　　要：为解决流域水资源开发利用过程中碳排放量计算和变化趋势预测问题,分析了流域用水能耗结构和二氧化碳排放机理,给出了取水系统、供水系统、排水与污水处理系统碳排放量计算方法,基于碳排放理论,构建了碳排放与耗水关联模型,并改进了传统的固定框架式IPAT模型,提出碳排放对生态环境的随机影响模型,进而以黄河下游东平湖流域为例,计算东平湖流域用水、碳排放量和排放强度。结果表明,东平湖流域近五年内平均年用水量为34 949×10^(4)m^(3),其中,农业用水(农林牧渔)占总用水量的79.1%;根据能耗计算,农业用水年平均碳排放量为405.59 kg,占流域平均碳排放总量的77.7%,其次为工业和生活碳排放量。To solve the problem of calculation and prediction of carbon emissions in the process of water resources development and utilization in a river basin, the structure of water energy consumption and the mechanism of carbon dioxide emission were analyzed. And then the calculation methods of carbon emission in water intake system, water supply system, drainage system and sewage treatment system were given. Based on the theory of carbon emission, a correlation model between carbon emission and water consumption was established. The traditional fixed-frame IPAT model was improved, and the stochastic impact model of carbon emission on ecological environment was put forward. Taking the Dongping Lake basin in the lower reaches of the Yellow River as an example, the water use, carbon emissions and emission intensity were calculated. The results show that the average annual water consumption of the Dongping Lake basin in the past five years is 34 949×10^(4)m^(3), of which the agricultural water consumption(agriculture, forestry, animal husbandry and fishery) accounts for 79.1% of the total water consumption. According to the calculation of energy consumption, the annual average carbon emission of agricultural water is 405.59 kg, accounting for 77.7% of the total average carbon emission in the basin. The second is industrial and domestic carbon emissions.
