Application of ecosystem value in policy system design: A case study of Fuzhou City, China.

On the basis of exploring the replicable, popularized and demonstrative accounting model of ecosystem value, it is critically needed to solve how to reasonably apply the accounting results of ecosystem value, form the application system of ecosystem value policy system, and promote the transformation of ecosystem service value from "accounting value" to "policy point". With the accounting of Fuzhou Gross Economic Ecological Product (GEEP) and Gross Ecosystem Product (GEP) as the starting point, we screened GEEP for indicators, calculated the green gold index and GEP per unit area, and analyzed the application mode in the policy and system design. The results showed that pollutant absorption, species conservation renewal energy values, wetland severe threat area proportion, air negative oxygen ions released volume, arable land occupancy rate, marine reclamation area proportion, carbon fixation quantity, oxygen release quantity, grassland cover change rate, coast protection area and environmental degradation cost of solid waste were the indicators significantly affecting the GEEP accounting results. The green gold index of Fuzhou City in 2015 and 2018 were 1.59 and 1.23, respectively, higher than that at the whole country level. The trends of GEP per unit area followed an order of wetland ecosystem> forest ecosystem> farmland ecosystem> grassland ecosystem> marine ecosystem. Based on the influencing factors of GEEP, green gold index and GEP per unit area, the management system and mode of "entering decision-making, planning, assessment and monitoring" of ecosystem values accounting results were constructed, which would provide a theoretical basis for the formation of a long-term mechanism for promoting the construction of ecological civilization in China.
