Research On The Coordination Between Ecosystem Service Value And Economic Development Based On LUCC

Land is the cornerstone of human survival and development,and it is also the platform for the stable operation of the ecological environment and socio-economic system.Ecological system is represented by land use type(land use cover),while socio-economic system is represented by human's land use mode.Human activities act on land resources to change their structure,thus causing changes in the types of land use and its area and spatial position,and thus causing changes in the structure and function of the ecological environment system.Based on the land use data of the Poyang Lake Ecological Economic Zone in2005,2010 and 2015,the ecosystem service value assessment method was used to calculate the ecological service value provided by land use in different periods of construction of the Poyang Lake Ecological Economic Zone.Utilize the ecological benefits generated.At the same time,the relationship between regional environmental protection and economic development is discussed by constructing the coordination index of ecological environment and economic development.Based on the changes in the driving force of ecosystem service value based on land use/cover change,the relationship between land type change and ecosystem service value is analyzed,which can serve the management of land use planning and integrated basic ecosystem service value.The research results are as follows:(1)land use classification: Poyang lake ecological economic zone has a high land use rate of 99.54%,of which the cultivated land accounts for 37.40%,which is a typical type of agricultural dominant land.But each county city land type has the big difference.During the study period,the land use of Poyang lake ecological economic zone changed dramatically.(2)the ecosystem services value aspects: land use/cover change make area ecosystem service value in the study period has been reduced,the Poyang lake ecological economic zone ecosystem services value in 2005-2010 to reduce 1.138 billion yuan,2010-2015,ecosystem services value loss of 1.534 billion yuan,eventually ecosystem services value loss of 2.672 billion yuan.The change of ecosystem service value and the spatial change of ecosystem service value in Poyanglake ecological economic zone are basically consistent with the trend of land use/cover change.In recent years,the ecological benefits of land use in Poyang lake ecological economic zone have decreased,and the ecological environment is not optimistic.(3)coordination between ecological environment and economic development:from 2005 to 2015,the overall ecological and economic coordination degree of Poyang lake ecological economic zone was at a low level of conflict,indicating that the overall ecological environment and economic development of Poyang lake ecological economic zone were in an uncoordinated state.From 2005 to 2010,except Anyi county,Fuliang county,Yingtan municipal district,Guixi city,Yujiang county,Yugan county and Wannian county as potential crisis areas,all the other counties showed low degree of economic coordination.From 2010 to 2015,the ecological and economic coordination level of each county and city was a low-degree conflict zone except that Anyi county,Leping city,Fuliang county,Yingtan municipal district,Guixi city and Yujiang county were potential crisis zones.The index value of ecological and economic coordination in the whole region decreased from-0.0061 in2005-2010 to-0.0068 in 2010-2015.The coordination levels were all low-degree conflict zones,the coordination between ecology and economy weakened slightly,and the ecological and environmental pressure for economic development increased to some extent.The economic development of Poyang lake ecological economic zone lags behind the coastal areas,and the economic construction lacks momentum.But at the same time,to some extent,it has enough space to think about the future development mode.Since the 21 st century,sustainable development has been the subject of the human and the nature harmonious development,how to use the concept of sustainable development to optimize and adjust the development ideas and strategy,how to balance the relationship between economic development and environmental protection,avoid “Development before conservation” mode,coastal developed areas of the teaching of the traditional development model brings serious ecological destruction is one of the major problems of Poyang lake ecological economic zone is facing.Through the above analysis,this paper believes that land resources are the platform for the stable operation of the two ecosystems,the ecological environment and the social economy.The utilization structure is closely related to the coordinated development of the ecological environment and society.Under the background of comprehensive consideration of ecological civilization construction,land use Structural optimization is an important way to achieve a circular economy and resource-friendly city construction.
