Research On The Coordinated Development Of Ecological Economy In Liaoning Province Based On Ecosystem Service Value

Ecosystem services refer to the various services and support functions that humans can obtain from the ecosystem.They not only maintain a relatively stable dynamic balance of the environment,but also provide material support for various ecological service functions,and also play an essential role in human activities.A reasonable land use model can not only effectively protect the ecological environment and improve the service value of the ecosystem to human society,but also ensure the stable and sustainable development of the social economy.This research adopted remote sensing data analysis,ecosystem service value equivalent factor method,regression analysis and other research methods.According to remote sensing data,we analyzed the changes of land use patterns in Liaoning Province in the past 10 years,quantitatively analyzed the dynamics and transfer of land use,and summarized its change laws.Based on this,we used the equivalent factor method and correction to estimate the ecosystem services values of study region,and discussed its temporal and spatial variation characteristics.Finally,we evaluated the gross domestic product of different land use types,constructed an ecological and economic coordination degree model,calculated the ecological and economic coordination degree,and used relevant statistical models to explore the ecological and economic coordination degree of Liaoning Province and the main social and economic factors that affect the ecological and economic coordination degree of Liaoning Province.The research results of land use dynamic change showed that the main land use types in Liaoning Province were cultivated lands and forest lands.During the study period,the change range and dynamic degree of cultivated land and forest land were relatively low.The land use dynamic degree of Liaoning Province increased during the study period,but the comprehensive dynamic degree was low(0.61%).Cultivated land and forest land were the two most converted land types during the study period.The research results of ecosystem service value showed that the total ecosystem service value of Liaoning Province were 112.6991 billion CNY in 2010,112.5161 billion CNY in 2015,and 119.2886 billion CNY in 2020.The overall value of ecosystem services showed a growth trend after a slight decrease.The value of ecosystem services provided by cultivated land,grassland and construction land decreased year by year,while forest land,water area and unused land first decreased and then increased.The results of the study on the degree of ecological economy coordination showed that the overall performance of the ecological economy development type in Liaoning Province during the study period changed from coordination(2010-2015)to coercion(2015-2020),while the ecological economy of each land type had gradually became coordinated.Among the main social and economic factors,the whole society’s fixed asset investment growth and passenger traffic were the main factors that affect the coordinated development of the ecological economy in Liaoning Province.This study briefly discussed the above research contents and results,and put forward countermeasures and suggestions.We proposed to strengthen the planning and control of land use,improve the value of ecosystem services,and promote the Liaoning regional economic development policy at the same time,in order to promote the coordinated development of Liaoning’s ecological economy.This study expected to provide an important basis for the sustainable development of the ecological environment and social economy through the research conclusions.
