Comparison of forest ecosystem services value evaluation methods: a case study of Sichuan Province, China.

The survival of human and sustainable development of the society both closely rely on forest ecosystem services. Employing two different methods, this paper based on benefit transfer method calculated the forest ecosystem services value of Sichuan province, China. The results showed that the total forest ecosystem services value had a steady rate of increase in Sichuan province from 2008 to 2018, and meanwhile, the different evaluation methods resulted in significant deviation of estimation outcomes. This paper considered the differences of biomass and socioeconomic development which were ignored in prior studies. The Carnegie-Ames-Stanford approach was employed to estimate the net primary productivity of different forest species. Further, the S type R. Pearl growth curve was employed to estimate people’s willingness and ability to pay for forest ecosystem services. This paper provided implications to help forest managers and policy makers pay additional attention to the evaluation systems choosing on forest ecosystem services value and the differences of biomass and socioeconomic development by using benefit transfer method method.
