Abstract
At present, the practice of water ecological compensation has been widely carried out in China, and the compensation standard is determined according to the protection cost, water quality standard and monetary value of water ecosystem. Few scholars measure the regional spillover value of water ecosystem services from the perspective of supply and consumption. Therefore, this paper estimates the regional spillover value of water ecosystem services in order to provide a new idea for setting compensation standards. Compared with monetary accounting, non-monetary accounting of regional spillover value of water ecosystem services avoids the adverse impact of market price distortion on the objectivity and robustness of accounting results.In this paper, emergy analysis method is used to calculate the non monetary value of regional spillover water ecosystem services. Firstly, the emergy analysis method is used to calculate the total energy value of water ecosystem services; Secondly, water footprint is used to characterize the self consumption of water ecosystem services; Thirdly, the regional spillover energy value is calculated by the difference between the total energy value of water ecosystem services and their own consumption, and the regional spillover value of water ecosystem services is obtained through the conversion of emergy currency ratio. Finally, taking the Loess Plateau Sichuan Yunnan ecological barrier area as an example, the total value of water ecosystem services, water footprint and spillover value of 37 national key ecological functional areas for soil and water conservation and 66 national key ecological functional areas for biodiversity maintenance are calculated. The results show that the ecological spillover value of 62 counties in the Loess Plateau Sichuan Yunnan ecological barrier area is greater than 0, which can be ecologically compensated, and the water ecological spillover value of 34 counties is less than 0, which can not be ecologically compensated.
