Research On Coordinated Development Of Land Use-Ecological Environment-Economic Development In Jiangxi Province

With the continuous development of society,whether land use is compatible with the ecological environment and economic development has attracted more and more attention.Land use is the basis of ecological environment and economic development.Ecological environment provides guarantee for economic development and land use.Economic development provides technical support for improving land use efficiency and protecting the ecological environment.The three systems of land use,ecological environment,and economic development affect each other.If a problem occurs in one system,it will affect the coordinated development of the entire society.At present,extensive land use is more serious,especially the rapid expansion of urban areas and the phenomenon of hollowing out of rural areas.The downward pressure on socio-economic development has increased,and the ecological environment problems such as sharp declines in forest resources and water pollution have become increasingly prominent.Based on this,research on the coordinated and coordinated development of the three systems of land use-ecological environment-economic development in Jiangxi province,find out the inherent development law between the three systems,accelerate the coordinated development of the three systems,and promote Regional coordinated development plays an important role.This paper analyzes the coupling and coordination of land use-eco-environment-economic development in time and space in Jiangxi province from2010 to 2018 by referring to relevant research content,using comprehensive evaluation models,grey correlation analysis methods,coupling degree models and coupling coordination degree models.The development status is selected at the spatial level in 2010,2015,and 2018 as the time cutoff.Using Arc GIS 10.2 software to analyze the spatial and temporal evolution of the coupling and coordination status of 11 prefecture-level cities in Jiangxi province.The degree of coupling and coordination among prefecture-level cities in2019-2025 was predicted.The results show that:(1)On the time scale,from 2010 to 2018,the coupling degree of land use-ecological environment-economic development in Jiangxi province is a high-level coupling,and the coupling status is good.From 2010 to 2018,the degree of coupling and coordination has also increased year by year,from 0.4586 in 2010 to 0.9417 in 2018.The average annual increase in coupling degree is 11.70%.The type of coupling and coordination has also been adjusted from the dysfunctional economic recession in 2010 to the lagging type in 2018 The year of high-quality coupling and coordination of land use lagging type,as a whole,from the verge of imbalanced decline adjustment to high-quality coupling and coordination,from economic development lag to land use lag.The coordinated coordination of land use-ecological environment-economic development at the prefecture-level cities as a whole has maintained a relatively steady and rising trend,indicating that the development of the three systems of land use,ecological environment and economic development in prefecture-level cities has been more stable in2010-2018.coordination.(2)From the perspective of space,in 2010,2015,and 2018,in terms of the degree of coupling and coordination between land use,ecological environment,and economic development in Jiangxi province,the pattern of spatial differentiation was higher in the north and lower in the south.It also reflects that the focus of Jiangxi’s social and economic development is in the north,and that the overall coupling and coordination degree of local cities at various levels has been relatively stable from 2010 to 2018.(3)From the perspective of important related factors,the more relevant among the land-use subsystems are the average GDP,the area of urban built-up areas,and the population density.Big.The use of pesticides in the ecological environment subsystem,the centralized treatment rate of sewage treatment plants,and the energy consumption per unit of GDP are more closely related to the ecological environment system.In the economic development subsystem,the urbanization rate,GDP per capita,and actual use of foreign capital are more closely related to the economic development system.
