Analysis On The Spatial And Temporal Evolution Of Beijing Ecological Space And Research On Influencing Factors

Beijing is a mega-city with a rapid growing economy and large population.Behind the prosperity,its ever-growing ecological problems,such as unbalanced developing conditions in different districts and ecological spaces,and unequal allocation of ecological resources,could not be neglected.In order to realize a relatively balanced development of ecological environment in various regions and improve ecological environment through the realization of joint prevention and control,it is necessary to delve into the spatial and temporal evolution of ecological space in Beijing,and to quantitatively analyze the factors influencing the above process on this basis.The main research methods used are as follows:(1)literature review and induction(2)exploratory spatial data analysis(3)panel data model and spatial measurement method(4)other quantitative analysis methods.The results show that the overall ecological space area of Beijing is gradually reduced,showing the stage,direction and overall dispersion of local aggregation.The retention of ecological space varies in different regions.The evolution of time and space are of significant differences.Furthermore,the ecological environment deficit per capita in Beijing as a whole and in each district is under great pressure,but the deficit level shows a downward trend.In addition,the ecological footprint and ecological carrying capacity of each district are obviously different,and the spatial effect is significant.Moreover,the area of ecological space is the main object of the study on the influencing factors of the evolution of ecological space volume.The indicators of permanent residential population,GDP,social investment in fixed assets,total output in agriculture,forestry,animal husbandry and fishery,proportion of GDP of tertiary industry,total retail sales of consumer goods and disposable income of urban residents all have significant influences.But the factors of ecological spatial quality evolution are diverse,the spatial spillover effect is significant,and the variables have different effects on different spatial effects.The paper has initiatively made a unified analysis and quantitative study on the evolution of ecological space from the core aspects of mass and quality;then,it narrows the research scale by accurately depicting the current situation of ecological space in Beijing;furthermore,it provides referencing value on how to improve ecological quality more scientifically,effectively and objectively in the formulation of regulatory policies.
