Study on the Contribution of CO2 Emission Reducing of Yellow River Upstream LONGyangxia and LIUjiaxia Cascade Reservoirs

In order to analyze the contribution of energy saving and emission reducing of Yellow River upstream LONGyangxia and LIUjiaxia cascade reservoirs, the compensation regulation simulation model of the Yellow River mainstream cascade reservoirs is adopted to study the dynamic characteristics of emission reducing contribution of Longyangxia and Liujiaxia reservoirs in three level years of 2005, 2015 and 2020. The result indicates that the emission reducing contribution of Longyangxia and Liujiaxia reservoirs are 15.8077 million ton, 16.1808 million ton, and 13.3092 million ton in 2005, 2015, and 2020 level years. The change laws of the Long-Liu compensation system emission reducing contribution is the same as the one of Longyangxia reservoir emission reducing contribution, which descends after ascending. The change laws of the Liujiaxia reservoir emission reducing ontribution is descending along with time.
