Value Assessment Of Forested Wetlands Ecosystem Services In Longwan National Nature Reserve, Jilin Province

The wetland ecosystemservice function has been one of the cutting edge studies both here and abroad wetland studies.With in-depth study of the wetlands,the innovation of the research methods of ecosystem service function,andavailable research data more accurate,forested wetlands ecosystem services has become a hotspot research.Longwan National Nature Reserve.is part of the typical volcanic landscape,with the succession of communityformed various wetland types in the region,andthe forested wetlandsare widely distributed in the southwest of Houhe river.This paper confirms the distribution of forestedwetlands in the Longwan National Nature Reserve,based on the result of the forested wetlandsinterpretation and field survey.This paper explores the value assessment system of temperate forested wetlands ecosystem service function,it quantitatively analyzes the function of forested wetlands ecosystem service function in Longwan National Nature Reserve,and quantifies the service function of forested wetlands.The paper first constructs the evaluation index system of forested wetlands ecosystem service function,and aims at the ecological support of forested wetlands,the social service of material production,the three kinds of ecosystem service functions.The main evaluation methods of market value,shadow engineering,carbon tax,afforestation cost and other assessment methodswere used to tentativelyassessthe 8 functions of water conservation,carbon fixation,climate regulation,soil protection,biodiversity protection,product production,education research,tourism entertainmentof forestedwetlands.Finally,according to the results of forested wetlands assessment in Longwan nature reserve,we can provide basic data support for the related indicators,provide scientific reference for the management,protection and restoration workof forested wetlands ecosystem in Longwan nature reserve,and provide an important basis for the proper utilization of wetland resources.The evaluation results show that the Longwan nature reserve forested wetlands service function value is totally 291.57×106yuan,includingwater conservation 14.34×106yuan,carbon fixation2.22×106yuan,climate regulation145.81×106yuan,soil protection 76.78×106yuan,biodiversity protection 0.61×106yuan,product production 49.26×106yuan,education research 1.14×106yuan,tourism entertainment 1.42×106yuan.Compared with the other ecosystem service function evaluation in other areas,itexplains the importance of protecting the function of forested wetlands ecosystem services.
