Cost accounting of ecological protection in the upper reaches of Yongding River

This study takes the upstream area of the Yongding River Basin in Zhangjiakou City as the research area, the input cost of ecological protection in this area is estimated. The dynamic cost algorithm is used to calculate the direct costs of the districts and counties of Zhangjiakou City during the period of “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan”. The indirect calculation method is used to estimate the opportunity cost of protecting the local ecological environment in Zhangjiakou City. Results show that the total direct cost of ecological protection per year in Zhangjiakou City is 330 144 000 CNY and the total opportunity cost per year is 2 595 391 000 CNY. The obtained results can be used as an important scientific basis for the development of ecological compensation standards across the Yongding River Basin in Zhangjiakou City.
