Study On The Evolution Of The "Production-Living-Ecological" Functional Pattern And Its Driving Factors In Duolun County,Inner Mongolia

Based on the land use data from 1995 to 2017 in Duolun County,Inner Mongolia,a"Production-Living-Ecological" functional land use classification system was constructed,and the spatial analysis function of ArcGIS was used to obtain "Production-Living-Ecological" functional pattern distribution map.Using spatial autocorrelation analysis and correlation analysis,from the perspective of Production-Living-Ecological function,analyze the spatial and temporal evolution of the "Production-Living-Ecological" functional pattern;by assigning the land use type of the "Production-Living-Ecological" function,from spatial heterogeneity and spatial correlation In terms of aspects,it reveals the characteristics of the evolution of the pattern of "Production-Living-Ecological ".Second,determine the trade-offs and synergy between various functions and analyze the distribution pattern.Finally,the Logistic regression model is used to analyze the driving factors of "Production-Living-Ecological" function.the result shows:1.The "Production-Living-Ecological" functional pattern in Duolun County has certain regularity in time change,spatial change,spatial heterogeneity and spatial correlation;the concentration level of the "Production-Living-Ecological”function shows a downward trend,and the degree of fragmentation is getting more and more the higher.The evolution of the"Production-Living-Ecological" functional pattern presents obvious regional differences.Overall,the production function space expanded slightly,but the function value decreased slightly;the Living function space expanded significantly,and the function value also continued to increase;the ecological function space shrank significantly,but the function value increased.The three types of functions showed strong spatial autocorrelation characteristics at multiple scales,with obvious spatial aggregation characteristics.During the study period,the spatial autocorrelation index decreased,indicating that the degree of spatial fragmentation increased.2.The "Production-Living-Ecological" function of Duolun County has a spatial synergy relationship between production-Living function.Production-ecological function and Living-ecological function are in a trade-off relationship.There is a spatial synergy between the functions,and there is a trade-off relationship between production-ecological functions and Living-ecological functions.The characteristic of change with time is that the spatial synergy relationship of production-Living function shows a trend of gradually weakening with time.The spatial trade-off relationship of production-ecological function shows a tendency of gradually weakening towards the direction of collaboration with time.The Living-ecological function space trade-off relationship is gradually increasing with time3.The production function,life function and ecological function pattern of Duolun County are all greatly influenced by socio-economic factors,among which the population density is more strongly affected.The second influential factor is the natural impact factor.The natural impact factor has a greater impact on the production function,life function and ecological function.
