| The Bohai Rim region is vast,and the cities in the region vary widely in terms of economy,population,and resource environment.Areas with a high level of urbanization have more job opportunities,better living environment and living standards,but at the same time,due to air,water,soil and other pollution,the construction of ecological livability may lag behind.In addition to the weak social and economic development and the low living conditions of residents in the areas with low urbanization level,there are also complicated environmental problems,which lead to the contradiction between the construction of ecological livable and suitable for work in the Bohai Rim region.Combining the new development concept,this thesis constructs an evaluation index system for ecological livability and work suitability in the Bohai Rim region,analyzes the time series and spatial characteristics of the development of ecological livability and work suitability in the Bohai Rim,and analyzes the spatial and temporal differentiation of the coupling coordination level of ecological livability and work suitability.Finally,the geographic detector model is used to explore the driving mechanism of the coordinated development of ecological livability and industry in the Bohai Rim,and corresponding countermeasures and suggestions are put forward.The main research conclusions are as follows:（1）The overall urban ecological livability and workability in the Bohai Rim region showed a fluctuating decline and fluctuating growth,respectively,and the spatial differentiation characteristics of the two were significant.From 2010 to 2019,the spatial differences in the overall ecological livability and workability of the Bohai Rim were mainly caused by the differences in the levels of ecological livability and workability in the three regions.The agglomeration of ecological livability level spatial distribution is relatively weak,while the spatial distribution of workability level is relatively agglomerated and has an obvious positive spatial correlation.（2）From 2010 to 2019,the coupling degree and coupling coordination degree of ecological livability and industry in the Bohai Rim region showed a slow growth state,and the coupling coordination level showed a spatial distribution pattern of "high coastal areas and low inland areas".The coupling coordination level shows the characteristics of developing from the center to the outside relying on the urban agglomeration.In terms of the overall spatial trend,the coupling coordination degree shows a pattern of high in the middle and low in the surrounding areas.The coupling coordination degree has a positive spatial correlation,and the spatial distribution is in a clustered state.The coupling degree and coupling coordination degree of ecological livability and work suitability are not uniform in spatial distribution,and the spatial combination types are quite different.（3）Analysis of the driving mechanism of the coupling coordination degree between ecological livability and workability.On the whole,the development of appropriate industry plays a leading role in the coupling and coordinated development of the two systems.The coupling and coordinated development of ecological livable and work-suitable in Bohai Rim is not the result of a single factor or a single system,but closely linked with other factors to jointly affect the development of the coupling and coordinated system,and the influence of the interaction of two factors is greater than that of a single factor.（4）According to the research results and combined with the requirements of high-quality urban development in the new era,the development of urban ecological livability and workability is proposed from four aspects: developing weaknesses in accordance with local conditions,accurately making up for basic gaps,clarifying the difference mechanism of influencing factors and coordinating the formulation of optimized regulatory policies. |
