Research On Three-Dimensional Ecological Footprint Of Jiangxi Province Based On Ecosystem Service Value

With the continuous expansion of population and rapid economic development,the contradiction between the ecological environment and human and land resources has become increasingly prominent.How to effectively evaluate the use of natural resources by humans and achieve regional sustainable development is a research topic that has aroused the government and academia highly valued.Jiangxi has a long history of agriculture,and the economic growth between its regions has always been maintained at a certain height.Quantitative measurement of the sustainable development level of Jiangxi Province is of great significance to the economic development and further rational planning of the region.The ecological footprint theory can measure the degree of human consumption of natural resources by analyzing the difference between supply and demand.The three-dimensional ecological footprint model makes up for the traditional model’s inability to distinguish between natural capital stock and flow by expanding indicators,so that the model has both time and space attributes.In view of this,this paper chooses to use the three-dimensional ecological footprint model when analyzing the changes in the ecological footprint of Jiangxi Province.In addition,the important factors that affect the results of the model measurement often only consider the supply services of the ecosystem,ignoring the regulation,support and cultural functions of the ecosystem,and fail to reflect the integrity of the ecosystem.This paper proposes to optimize the three-dimensional ecological footprint model based on the ecosystem service value theory when calculating the ecological footprint model factors to better reflect the differences in the ability of different ecosystems to provide ecological services.In a nutshell,the innovations of this article are mainly reflected in three aspects:(1)Calculated the ecological footprint model factors based on the value of ecosystem services,and optimized the model parameters;(2)Introduced footprint depth and breadth indicators,and expanded the dimensions of the ecological footprint model;(3)With the help of STIRPAT The model expands the three-dimensional ecological footprint influencing factor indicators,which can better reflect the actual situation of Jiangxi Province.This study firstly calculated the equilibrium factors and yield factors of the six major biological productive lands in Jiangxi Province from 2006 to 2018 based on the theory of ecosystem service value,and then established the ecological carrying capacity account and ecological footprint account in line with the actual situation of Jiangxi Province.Construct a traditional two-dimensional ecological footprint model to calculate the ecological carrying capacity and traditional two-dimensional ecological footprint of Jiangxi Province from 2006 to 2018;secondly,add indicators to construct a three-dimensional ecological footprint model,and complete the measurement and analysis of relevant indicators of the three-dimensional ecological footprint;Finally,according to the measurement results,the STIRPAT model between the three-dimensional ecological footprint per capita and the driving factors was constructed in conjunction with the actual situation of Jiangxi Province,and the R software was used to perform partial least square regression analysis to explore what caused the three-dimensional ecological footprint of Jiangxi Province.Variety.After empirical research,the conclusions of this article are as follows:(1)The values of ecological footprint model factors in different studies are quite different;(2)Jiangxi Province has always had an ecological deficit during 2006-2018;(3)In 2006-2018,the stock capital needs to be consumed every year to meet the production and consumption needs of Jiangxi Province.(4)The three-dimensional ecological footprint is affected by factors such as population size,affluence,and technological level.In order to solve the deficit problem and realize the sustainable development of Jiangxi Province,the suggestions made in this article are:(1)Reasonably regulate the population size and continuously optimize the population structure;(2)Promote the transformation of economic development mode and promote the optimization and upgrading of the industrial structure;(3)Strengthen scientific and technological innovation to science and technology improve the environment;(4)optimize the spatial layout of land use and increase the carrying capacity of the ecological environment.
