Study On Tangshan Industrial Ecosystem Adaptation Based On The Theory Of Ecological Niche

The global ecological environment system is facing unprecedented challenges,which is closely related to the long-term and high-intensity industrial development of human beings.Countries around the world pay more and more attention to the development of circular economy.China has also made unremitting efforts to build a resource-saving society and promote economic and social sustainable development.In the context of the coordinated development of Beijing,Tianjin and Hebei,Tangshan,as a century old industrial city and resource-based city,plays an important role in undertaking the transfer of the secondary industry in Beijing and Tianjin.Under the constraints of energy consumption and pollution,Tangshan is facing tremendous pressure of industrial structure transformation and optimization and upgrading.How to realize the development of industrial ecosystem and improve its adaptability under the current development environment and many constraints is the focus of current research.First of all,the relevant theories and literature at home and abroad were summarized,and it was found that there was almost no research on the single urban niche and industrial ecosystem adaptability.Secondly,this paper analyzed the economic and industrial development status of the whole country,Beijing,Tianjin,Hebei and Tangshan,and focused on the analysis of the secondary industrial structured by industry.Then,based on the theory of niche,a three-dimensional index system was constructed,and the niche of the whole country,Beijing,Tianjin,Hebei and Tangshan was quantitatively evaluated and compared by catastrophe progression method.Further,the combination weighting method of principal component analysis and entropy weight method and the system coordination degree model were used to evaluate the adaptability level of industrial ecosystem in Tangshan.Finally,on the basis of the research results,drawing on the advanced experience of industrial ecology construction at home and abroad,and considering the layout and development status of Tangshan industry,the paper made a tentative plan to optimize the industrial ecosystem of Tangshan City,and puts forward relevant policy recommendations.The main conclusions of the study are as follows: first,Tangshan City has a prominent niche advantage in social dimension,that is,urban infrastructure construction and residents' living comfort,and has a niche overlap with Beijing in economic dimension.Second,the adaptability level of industrial ecosystem in Tangshan city is most closely related to stability and sensitivity index.Four factors,namely basic development,factor investment,environmental treatment and pollution discharge,are the prominent problems restricting the improvement of the adaptability of industrial ecosystem in Tangshan city.The overall adaptability level and the coordination degree among factors are low.Third,the pension industry,a unified information research platform,new enterprises and landscapes in the virtual industrial park can be used as new nodes to play a positive role in taking advantage of Tangshan city's niche,improve the adaptability of the industrial ecosystem and promote the optimization of the industrial ecosystem.Figure17;Table11;Reference 63...
