Evaluation of Ecosystem Service Value in Wenzhou City Based on Land Use Change
[Purposes]Through the study of land use changes and ecosystem service value in Wenzhou City in the past 20 years,we aim to understand the ecological comprehensive improvement effect of Wen-zhou City,provide a scientific basis for spatial planning,ecological comprehensive protection,and policy formulation,and assist the urban development of Wenzhou City.[Methods]This article is based on land use data from 2000,2010,and 2020,and uses methods such as area transfer matrix and land use dy-namic degree to simulate and analyze the dynamic changes of land use in Wenzhou City from 2000 to 2020.Based on the improved Xie Gaodi Ecosystem Service Value Equivalence Table,the ecological ser-vice value of Wenzhou City during the research period is quantitatively analyzed.[Findings]① Wen-zhou City has the largest forest area,with both forest and water areas on the rise.Construction land has significantly expanded,seriously encroaching on surrounding farmland;② From 2000 to 2020,the over-all value of ecosystem services in Wenzhou City has been on the rise,with forest land accounting for the most significant contribution,accounting for over 80%;③Throughout the entire research period,indi-vidual ecosystem services were characterized by regulatory services>supportive services>supply services>cultural services.[Conclusions]The research results indicate that the ecological protection in Wen-zhou City has achieved significant results over the past 20 years,and the ecological environment has been significantly improved.
