Research On Man-land System Space Equilibrium Of Yellow River Delta Efficient Ecological Zones

With the rapid development of China's economy in the past 30 years,the intensity of regional development has been enhanced,the speed has been accelerated and the spatial scale has been expanded.The spatial equilibrium pattern has changed dramatically,because of the carrying capacity of regional resources and environment has decreased and the damping effect of resource environment on social and economic activities has gradually increased.Based on the characteristics of the economic,social,resource and ecological environment of the Yellow River delta efficient ecological economic zones,in the perspective of regional sustainable development,this paper analyzes the characteristics of the "three-dimensional space","supply demand",and " three-dimensinal target " to achieve the spatial balance of the three levels of the Yellow River delta efficient ecological economic zones.Respectively,to build "three-dimensional space","supply demand" and "three-dimensional target" indicator system,using the entropy TOPSIS method to quantitatively evaluate the spatial equilibrium pattern of sustainable development of the Yellow River delta efficient ecological economic zones from three levels,which is of great significance for the study of spatial equilibrium pattern of typical ecological fragile man-land system.The paper draws the following conclusions:(1)There are 7 types of land and sea spatial equilibrium types in the "three-dimensional space" of the Yellow River delta efficient ecological economic zones,which are mainly composed of ? production-living space lag type,? ecological space lag type and IX high level spatial equilibrium type.The low level of development of the "production space" is concentrated in the urban areas of the northern wing,showing a clear spatial distribution of the south and north,the southern region higher and the northern region lower.The low level of development of the "living space" is concentrated in the urban areas,showing the southern region higher and the northern region lower,and the development level of the "ecological space" in eastern wing is better than that of the western wing.(2)There are 5 types of spatial types of resources and environment in the "supply demand" of the Yellow River delta efficient ecological economic zones,which is dominated by the ? high level of spatial equilibrium type and the ? lack of development type.19 counties and cities in the regional supply capacity,demand intensity development is not the same,and the spatial distribution of the situation is quite different.The areas with strong supply capacity are concentrated in the the central region,and the areas with weak supply capacity are concentrated in Gaoqing,Binzhou urban area and Zhanhua.The areas with large demand intensity are concentrated in the central region,and the areas with less demand intensity are concentrated in the west wing areas.The imbalance of regional demand intensity is affected by economic base,resource endowment,government policy and social development,(3)The equilibrium of economic,social and ecological environment under the "three-dimensional goal" includes five types of the Yellow River delta efficient ecological economic zones,which are mainly composed of ? economic-social lag type and ? high-level spatial equilibrium type.19 counties and cities have low-level spatial equilibrium model,but also have a high level of spatial equilibrium model.Higher areas of economic development are concentrated in the central and eastern districts of the county,the lower areas are concentrated in the western region of the county;the higher levels of social development concentrated in the central counties,the lower areas concentrated in the west of the county;urban areas with high levels of development of the ecological environment concentrated in the western counties and cities,the lower areas concentrated in the eastern wing of the county.Economic,social and ecological subsystems,the intensity of the interaction between the economic,social and ecological subsystems is generally better than that of the eastern wing and the west wing.(4)The spatial equilibrium state assessment of the Yellow River delta efficient ecological economic zones from the perspective of regional sustainable development in the three aspects of " three-dimensional space","supply demand" and "three-dimensional goal",shows that he sustainable development of man-land system in the Yellow River delta efficient ecological economic zones is not only faced with the space equilibrium,but also faced with the problem of space imbalance.East wing area in the space is not balanced counties(cities)mainly concentrated in Hanting District,Laizhou City and Shouguang City.The counties(cities)in the middle of the region are mainly concentrated in Lijin County and Boxing County,but in the middle of the " three-dimensional space" level,the central region is in a spatial imbalance.The west wing area is a region where the spatial distribution of the hilly area is concentrated in the Yellow River delta efficient ecological economic zones,where the "three-dimensional space" and the "three-dimensional goal" are not balanced.The county(city)covers almost all the western wings.In the three dimensions,the "ecological space" is the most important factor in the overall improvement of the regional "three-dimensional space".(5)The relationship between "human" and "land" in the Yellow River delta efficient ecological economic zones is not yet coordinated.In order to promote the spatial pattern of sustainable development in the Yellow River delta efficient ecological economic zones,the coordinated development of man-land relationship should speed up the industrial structure adjustment and implementation of eastern area efficient,high-end and high-quality industrial development strategy,accelerate the transformation of economic development.Multi-pronged approach to promote the sustainable development of the western region,to build a rational development strategy,standardize human development activities,to seek "production space","living space" and "ecological space" balanced development.Innovation and industrial development system,promote the "production space" to green growth transformation,innovation social governance system,comprehensive management of "living space",innovation and ecological civilization system,attention to "ecological space" construction.This paper is divided into seven chapters: the first chapter is the introduction,which mainly explains the research background of the thesis and the significance of selecting the high-efficiency ecological zone of the Yellow River delta efficient ecological economic zones as the research object.At the same time,it elaborates the research content,technical route and research method.The second chapter is a summary of domestic and foreign research,from the perspective of geography,economics,management,ecology and other diffferent subject to compare "human system" study at home and abroad.It sorts out,sums up the regional sustainable development research,finds the Yellow River delta efficient ecological economic zones human system existing research deficiencies,and puts forward the innovation of this article.The third chapter is the basic theory and the concept of discrimination.Based on the theories of regional sustainable development theory,man-land relationship theory and spatial equilibrium theory,this paper analyzes the related concepts such as regional sustainable development,ecological fragile man-land system and regional sustainable development perspective.The fourth chapter is the study of different types of spatial equilibrium in the efficient ecological zone of the Yellow River delta efficient ecological economic zones.This paper constructs the interaction model between "human" and "earth" from three aspects: "three-dimensional space","supply demand" and "three-dimensional goal" from the perspective of regional sustainable development,and develops the spatial equilibrium type the study.The fifth chapter is the analysis of the driving mechanism of the spatial equilibrium pattern of human and local systems.The influencing factors of spatial equilibrium of man-land system are analyzed from four aspects: natural environment foundation,industrial structure change human demand and regional development strategy.The sixth chapter is the suggestion of the balanced development of man and land system in the efficient ecological zone of the Yellow River delta efficient ecological economic zones.From the control of the "people" and "ground" interaction in eastern wing,central and western wings,improve the "three-dimensional space" coordination,and so on to optimize the ecological fragile man-land system "people" and "ground" interaction suggestions on spatial structure.The last chapter is the conclusion and the prospect,through the research content and the results of the comb,summarize the basic conclusions of this paper,and put forward the research outlook.Among them,the fourth chapter and the fifth chapter is the main chapter of this thesis.
