Study On The Spatial And Spatial Pattern Evolution Of "Three Lives" Along The Yellow Township Of Gansu Province

With the rapid economic development and urbanization process accelerating,the urban system is improving,the competition between regions is becoming more and more intense,and central cities and urban clusters become the main spatial forms for carrying development elements.As the rapid socio-economic transformation is not synchronized with the expansion of the main space,the unbalanced development of different functional spaces and the continuous deterioration of ecological environment,people are more and more urgent to realize a new spatial pattern of the national territory.As an important ecological security barrier and important water connotation area in northwest China and the center of socio-economic development of the province,the coordinated socio-economic development and reasonable layout of spatial structure in Gansu Province along the Yellow Townships are of great significance to narrow the intra-regional differences and contribute to high-quality regional socio-economic development.In this paper,we select the Yellow Town Belt in Gansu Province as the research object,follow the technical route of "identification-management-optimization",use remote sensing images,urban land use survey data and relevant statistical data as the main data sources,and use the period of 2005-2020 as the research period,adopt the dynamic attitude model,land use transfer matrix,comprehensive index analysis,and the kernel density estimation analysis,SPSS correlation analysis.The spatial analysis of "three lives" in Gansu Province along the yellow town belt is carried out by using methods such as kernel density estimation analysis,SPSS correlation analysis and Geoda spatial autocorrelation analysis to identify the spatial types of "three lives",construct a functional evaluation index system of "three lives",and analyze the spatial temporal distribution of "three lives" in the research area."Based on the above research results,we introduce the comparative advantage theory to determine the optimal spatial zoning of "three living" in the study area and put forward targeted countermeasures and suggestions,so as to provide scientific basis for ecological protection and high-quality development of urban clusters in the Yellow River Basin.This study provides scientific basis for ecological protection and high-quality development of urban clusters in the Yellow River Basin.The conclusions of the study are as follows:(1)The "three living" spaces along the yellow town belt(Gansu section)have relatively obvious geographical differentiation characteristics.From the characteristics of area change,the main spatial type in the study area is ecological space,the scale structure has not changed significantly;production space as an important part of the "three living" spatial land transfer,the scale and proportion of land gradually shrinks with the evolution of time,arable land protection is not optimistic;living space gradually The economic and demographic factors are the main factors driving the change of living space.From the structural change characteristics,the production and living space distribution in the study area has overlapping,with Lanzhou-Baiyin metropolitan area and Linxia Prefecture as the core expanding to the surrounding areas,and the ecological space distribution with Jingtai County,Yongjing County,Dongxiang County and the whole Gannan Prefecture as the core expanding to the surrounding areas,in general,the production and living space polarization direction and ecological space dispersion characteristics are obvious,and it is necessary to carry out It is necessary to carry out the optimization of the spatial pattern of "three lives".(2)The spatial land use trade-offs of the "three living" areas along the Yellow Township(Gansu section)are greater than the synergistic effects.In terms of spatial trade-offs and synergistic relationships,the synergistic relationship between production and living space is enhanced in the temporal scale,and the trade-offs between production and living space and ecological space are weaker,while the trade-offs between different secondary functional spaces are dominant and the synergistic relationship is weak.The same land use space under spatial scale shows significant synergy,and the global autocorrelation coefficients of different land use spaces have obvious trade-offs,and the trade-offs and synergy types are mostly distributed in groups,with less scattered distribution.(3)Factors influencing the evolution of the spatial pattern of the "three lives" along the yellow town belt(Gansu section): natural environmental factors are conducive to the sustainable development of production and ecological space,socio-economic factors are gradually changing the spatial pattern of living along with the different development stages and development needs of the city,and public policy factors are actively promoting the spatial integration of the "three lives" in the study area from division to system.(4)In summary,based on the analysis of the spatial-temporal pattern variation characteristics and influencing factors of "three living" along the yellow town belt(Gansu section),the comparative advantage theory is introduced to divide the study area into six kinds of optimization zones: production function advantage zone,living function advantage zone,ecological function advantage zone,production-ecological function advantage zone,production-living function advantage zone and living-ecological function advantage zone,and countermeasures and suggestions are proposed for each advantageous function zone.
