Research On The Delimitation Of The Ecological Space Of Territorial Resilience Based On The "three Births" Game

With the acceleration of urbanization process and the constant expansion of city and rural construction land,ecological space has been seriously squeezed and encroached by production space and living space,and the proportion of land spatial structure of "production-life-ecology" tends to be out-of-balance.The traditional thinking of bottom line protection with "ecological red line" as the main body is unable to solve complex problems of ecological environment system.To this end,it is necessary to change from bottom-line thinking to precausal thinking,and to build a resilient ecological protection space in order to effectively improve the protection capacity of land ecological space.This paper takes the resilient ecological space of land as the research object,uses methods such as statistical analysis,spatial analysis and game analysis,centers on the competition process of production-living-ecological spaces and investigates the action mechanism of the evolution of land ecological space in the competition.By constructing the game pay-off matrix of production-living-ecological spaces,the optimal decision scheme of the allocation of land production-living-ecological spaces is obtained,and the study of land resilient ecological space delimitation is completed based on the suitability of land ecological space and conflict analysis of production-living-ecological spaces.Firstly,through the analysis and study of the space-time evolution pattern of production-living-ecological spaces in Tianjin,it is concluded that under the dual driving action of urbanization and industrialization,the proportion of the area of living space and industrial and mining production space in Tianjin has been increasing year by year over the past 16 years,and the demand for construction land expansion has been met by occupying agricultural production space and ecological space,thereby leading to prominent structural contradictions of the land of production-living-ecological spaces.Meanwhile,management and control of ecological space has become the key task of ecological protection.Secondly,this paper uses evolutionary game model to analyze the evolutionary game process and influencing factors of the optimal allocation of production-living-ecological spaces,and comprehensively considers and balances regional economic society and ecological protection and construction.Local governments scientifically reward or punish the behaviors of protecting or destroying the ecological environment,so as to produce positive benefits and increase the possibility of achieving optimum equilibrium of the game.Thirdly,based on the study of the game relationship of the production-living-ecological spaces of land,the direction of ecological space optimization is explored in two dimensions of space conflicts and ecological suitability.The results show that the conflict intensity of production-living-ecological spaces in Tianjin is continuously increasing and the conflicts present a pattern of"Low intensity conflicts reduce year by year,high intensity conflicts concentrate and expand in series".There are great differences in the composition of conflict level between different spatial types.Thereinto,the conflict intensity of ecological space is the lowest.Highly suitable areas of land ecology are mainly concentrated in Jizhou District and Beidagang Wetland Nature Reserve.The ecology suitability of the four districts around the city and the five districts in outer suburbs is generally low.Binhai New Area,an accumulation area of regional construction land,has the lowest ecology suitability.Fourthly,in view of the production-living-ecological game,spatial conflicts and ecological suitability evaluation,using GIS platform,the resilient ecological space in Tianjin is divided into four types of ecological protection area,ecological restoration area,ecological cultivation area and ecological agriculture area,and they together account for 30.24%of the total area of the research area.As to resilient ecological space,on the premise of strictly executing the hard constraints of the ecological red line,the room for optimization and adjustment is reserved,and the adjustable range of resilience is clarified to act as a buffer and safety guarantee to resist external disturbance and conflicts and maintain the stabilization of the ecosystem,thus reducing and avoiding the ecological damage caused by forcible occupation of the ecological space.
