Value Assessment of Ecosystem Service Function of Ecological Public Welfare Forests in Wenchang City

Based on the measurement parameters and index in the Specifications for Assessment of Forest Ecosystem Services in China(LY/T 1721-2008),the value of ecological service functions of ecological public welfare forest in Wenchang City was evaluated and analyzed.The results show that the total value of ecosystem service function of ecological public welfare forests in Wenchang City is about 4.020 billion yuan,of which storage capacity,water purification,soil fixation,fertilizer(N,P and K fertilizer) conservation,carbon sequestration,oxygen release,forest nutrient accumulation,providing anion,absorbing SO_2,absorbing fluoride,absorbing NxO,absorbing soil heavy metals,dust retention,noise reduction,sterilization,forest protection,forest biodiversity protection,and forest recreation(ecological tourism) are about 1.510 billion,582.256 million,3.769 million,268.220 million,116.360 million,2.747 million,22.682 million,42.817 million,1.722 million,74,600,131,900,187.918 million,77.409 million,28.721 million,43.090 million,180.696 million,571.036 million,and 108.677 million yuan

Market-based instruments for ecosystem services:framework and case study in Lishui City,China

Introduction:Effective provision of ecosystem services(ES)and improvements in well-being of residents can be realized through policy interventions of stakeholder behavior.Of the several policies,market-based instruments(MBIs)have become the focus of global attention.Outcomes/others:To couple the theory with practice and solve the key problem of unclear definition of property rights,the framework of MBIs is designed.First,property rights of market creation must be clearly defined,verifiable,transferable,enforceable,and have policy continuity.Then,four key characteristics of MBIs need to be considered in the case design,namely those involving ES,stakeholders,trading mechanisms,and guarantee mechanisms.The Pledge Financing of the Right of the Ecological Public Welfare Forest(PFREPWF)in Lishui City is a typical case of China’s current marketization,which is a supplement and improvement to the ecological compensation policy.Based on clearly defined contract rights,Lishui City has realized the integration of ecological compensation and credit creation.Discussion:The case design still has the problems of lack of quantification and lack of correlations with ES.Conclusion:The theoretical and practical analysis around the market mechanism has reference value for solving market failures and providing environmental services.
