Study On The Function Compound System Of “Production-Living-Ecology” In Chengdu-Chongqing Economic Circle

The spatial functional system of urban agglomeration requires positive interaction and coordi nated development of “production-living-ecology” functional system.As an important urban com munity in the western part of China,it is necessary to study and analyze the complex system of “p roduction-living-ecology” function in Chengdu-Chongqing Economic Circle.This paper conducts a comprehensive study of urban agglomeration functional system from t he perspective of complex systems,and builds a theoretical model of “production-living-ecology”functional complex system with the help of system theory.Based on the scale of urban agglomerat ions and interdisciplinary perspectives,the development goal of the “production-living-ecology” f unctional complex system is defined as the sustainable development of the system,and the goal ne eds to be realized through the improvement of the development level of “production-living-ecolog y” function and the coupling and coordinated development of “production-living-ecology” functio n.Then,the “production-living-ecology” functional complex system is studied from the perspecti ves of development,coordination and interaction.This paper tries to discuss the development mec hanism and law of “production-living-ecology” function in urban agglomeration from the perspect ive of system integration.Based on the above framework,this paper studies the development level,the degree of coupli ng and coordination development and the influencing factors of the “production-living-ecology” f unctional complex system of Chengdu-Chongqing Economic Circle,and draws the following con clusions:(1)The three subsystems show an overall growth trend from 2011 to 2020,and the devel opment level at the end of the study is ranked as ecology function,production function,living func tion;The production function and living function have the trend of “multi-polarization” developm ent,while the ecology function appears the trend of “two-wing” development to “central collapse”.(2)Although the development of production functions,living functions and ecology functions of t he research units are not synchronized during 2011-2020,the coupling coordination degree of “pro duction-living-ecology” functional complex system has increased,from “high coupling and low c oordination” to “high coupling and middle coordination”;The spatial distribution shows the chara cteristics of “Chengdu-Chongqing dual-core development and central belt collapse”.From 2011 to2020,Moran’s I of the coupling coordination degree of the overall “production-living-ecology” fu nctional complex system in the research unit was significantly negative and the absolute value incr eased year by year.The local Moran scatter in 2011 and 2020 mainly distributed in the second qua drant,forming “low-high” subsidence area.(3)Economic scale,scientific and technological level and ecological service are the main barriers to the development of the subsystems of overall produ ction,living and ecology function of the research unit.There are three types of grey correlation val ues,among which “production function> ecology function> living function” type accounted for 81.25% of the total in the study area.Based on the above analysis,this paper adheres to the coordin ated development strategy of urban agglomeration with overall planning and differential positioni ng;Promote development for the benefit of all and promote the construction of urban agglomerati on living functions;To promote better alignment between well-functioning governments,efficient markets and organic societies.
