Abstract:

Objective: Forest ecological compensation is an important measure to deal with environmental degradation and balancing regional development. Combined with the theory of forest ecosystem service flow and based on the direction of forest ecological benefit, horizontal compensation standards for forest ecological benefit from water retention service were studied in order to provide a scientific basis for improving the cross-provincial watershed forest ecological compensation mechanism. Method: Taking the Tingjiang (Hanjiang) river basin as an example, the equivalent factor method, water footprint method and gravitational model were used to study the overflow value of forest water retention services and their spatial transfer in the watershed under study to determine the compensation standards balancing the benefits between the receivers and the suppliers of compensation, Result: 1) The spillover value of forest water retention service in Longyan City, Zhangzhou City and Sanming City in the upstream area of the Tingjiang (Hanjiang) river basin was approximately RMB 804.49 million , RMB 58.57 million and RMB 130.38 million respectively. Guangdong Province should pay a total of about RMB 993.45 million in ecological compensation funds for water conservation to Fujian Province. 2) The region with the widest radiation area provided by Sanming City, Zhangzhou City, and Longyan City was Meizhou City, and Meizhou City undertook the main ecological compensation funds. 3) Longyan City received the most water-containing horizontal ecological compensation funds, accounting for 80.98% of the total compensation funds. The largest forest ecological compensation amount for forest water retention paid by Meizhou City, accounting for 88.89% of the total ecological compensation funds. Conclusion: The upstream areas of the watershed all have the spillover value of forest water retention services, with different radiation range and radiation amount to the downstream areas. The horizontal ecological compensation funds paid by the downstream beneficiary areas of the studied watersheds do not exceed 1% of the local GDP, which has good feasibility in compensation practice and it provides a scientific basis for the formulation of horizontal compensation standards for forest ecological benefits in watersheds.
