Calculation of air environment compensation benefits of Yellow River upstream cascade reservoirs
This paper gives the connotation and calculation method of air environment compensation benefits of reservoirs,and establishes a compensation regulation model for cascade reservoirs system.This model is applied to the mainstream cascade reservoirs of Yellow River,and the air environment compensation benefits and dynamic variations of Longyangxia and Liujiaxia reservoirs in the three level years 2000,2010 and 2020 are studied in details.Results show that the total compensation benefits of these two reservoirs to the mainstream reservoirs in the three years are 35.5674,36.4068 and 29.9457 million yuans,respectively.The time variation of these benefits shows a trend of descending after ascending as the Longyangxia case,while Liujiaxia reservoir shows monotonic descending.
