| The three functional spaces of agricultural production space,urban and rural living space,and blue-green ecological space are the most important components that support the normal and healthy operation of the Earth and human ecosystem,and are the main objects of China’s territorial space planning and management in the new era.Studying the game evolution process of the three types of functional spaces during the past "multi planning conflict" period can provide a reference for formulating more scientific and reasonable land space planning and regional coordinated development strategies in the future.From the perspective of game theory,combined with traditional spatial evolution process analysis,based on 30 m resolution land use data(1980,1990,2000,2010,2020),and using the Arc GIS10.8 spatial analysis platform,this study developed a quantitative research framework for spatial game processes,and proposed a measurement method for spatial game types and spatial game intensity.At the county level,This paper quantitatively studies the game evolution process of three types of functional spaces in Henan Province over the past 40 years,and further reveals the driving force mechanism of the evolution process of the spatial game using a grey correlation model;Use spatial autocorrelation analysis to identify key regions with typical spatial game phenomena,and use the MOP-PLUS model to predict the game evolution results of the three types of functional spaces in key regions in the future.The main results of this study indicate that:(1)From 1980 to 2020,the spatial game process of various counties in Henan Province has significant spatiotemporal differences and spatial agglomeration characteristics.The game intensity of the three types of functional spaces decreased from low to high,and the spatial game types returned from positive sum to zero sum and then to positive sum.The year 2000 was an important turning point for the intensity and type of spatial games.The period 1990-2000 was the period of maximum game intensity for the three types of functional spaces,as well as the period of maximum spatial transfer intensity and landscape pattern change intensity.(2)The higher the level of urbanization,the greater the intensity of spatial game,and the stronger the conflict between functional spaces.Urban centers with higher levels of urbanization are represented by a zero sum game at the expense of agricultural production space.County areas on the urban fringe and urban development axis often have the most variable types and intensities of spatial game,and are also the areas with the highest degree of coordinated development among the three functional spaces.(3)The game and conflict between urban and rural living space and agricultural production space mainly occur in counties in plain areas,while the game and conflict between urban and rural living space and blue-green ecological space mainly occur in the periphery of cities with high urbanization level,while the conflict between agricultural production space and blue-green ecological space mainly occurs in more remote mountainous areas.(4)In the future,under the guidance of the concept of life community development,as the focus of urbanization shifts to counties,different development strategies should be formulated based on the specific circumstances of different counties and districts,to improve the degree of cooperation between different functional spaces and optimize the spatial layout by improving the connectivity of similar functional spaces,balancing their spatial scale and landscape advantages based on development needs and major contradictions,and so on,To better promote the coordinated and sustainable development of the three functional spaces.(5)The tertiary industry,terrain niche index,and population size are the main factors that affect the evolution process and spatial heterogeneity of the three functional spatial games.The spatial game intensity in Zhengzhou and its surrounding areas is high and has significant spatial autocorrelation.(6)Based on the multi-objective function of the MOP-PLUS model,the spatial game process of three types of functional spaces in Zhengzhou in the next 10 years is simulated under multiple scenarios.The results show that the best land for both ecological and economic benefits is 60% for agricultural production space,30% for urban and rural living space,and 10% for blue-green ecological space. |
