| The Yellow River Basin,Yin Shan mountains,Erdos Plateau and Hetao plain together comprise a complex topographic topography along the Yellow Region in Inner Mongolia.Inner Mongolia along the Yellow region has historically been the intersection of nomadic culture and agroforestry culture,with the Yin Mountain and Yellow River forming the demarcation line of its ecological environment.Historically here were regions in which the nations had intermingled and their territories had changed,forming political,economic,and cultural connections,which were jointly developed by the peoples,and in which many cities had been established.These cities,mostly serving to defend Krai minorities,are concrete manifestations of territorial cultural traits and connotation,and serve as the material vector for the cultural development of the Yellow River.Most of the previous studies were on the nature,scale-up shaping,internal functioning of the single ancient city,or on the spatial distribution of the ancient city during a certain historical period,and few studies were conducted on the spatial distribution of the ancient city from a macro regional perspective,ranging from the Warring States Period to the end of the Qing dynasty(475BC.-1912 AD.).In this context,in response to the spatial distribution problem of the ancient city along the Yellow Region of Inner Mongolia,a qualitative and quantitative analysis based on architecture,ekistics,history,and urban geography is performed using a geographic information system(GIS)to reveal the characteristics of the spatial distribution and the changing rules of spatial development of the city from the Warring States Period to the end of the Qing dynasty.In this thesis,a total of 298 ancient city of Bayannor City,Baotou City,Hohhot City and Erdos City during the Warring States Period to the end of the Qing dynasty were used as the research objects,and the basic data of the ancient city were collated and collected according to the members of the subject group and the author,and the basic data of the current state were collated and summarized in two parts,one being basic geographic data:slope,aspect,elevation,longitude,latitude,and so on;The second is ancient city data: the chronology of the city construction,the administrative hierarchy,the administrative affiliations,the size scale hierarchy,the nature of the city,and so on.Based on the status quo information data,we divided the into five historical periods according to their historical development characteristics: the war States period(475-221 BC),the Qin and Han Chinese period(221-220 BC),the Suitang period(220-907),the Liaojin period(907-1368),and the Ming and Yang periods(1368-1912),analyzed with GIS superimposition The overall spatial distribution of the historical cities these five periods was investigated by digital topography and nuclear density analysis,which was mainly divided into two main parts: first,the spatial distribution of the cities in terms of their natural attributes,mainly referred to the longitude latitude distribution of the cities,slope slope distribution,elevation distribution,and so on;The second was the distribution of the social attributes of the city pool which mainly referred to the spatial distribution of administrative ranks,the distribution of scale ranks,the continuity distribution,the distribution of the city density,and so on.Finally,analysis of the spatial distribution of the GIS,analysis of the mean distance,analysis of the coefficient of variation,and mapping functions were used to investigate the characteristics of the city ’s spatial distribution and the law of change in development at the macro level,as well as to examine the factors influencing the spatial distribution of the historical city.Through the spatial analysis and study of the historical city along the Yellow Region of Inner Mongolia,the following conclusions are mainly drawn:1.City distribution longitude latitude analysis,most historical cities were distributed between 110 ° e-112 ° e,40 ° n-42 ° n;City slope analysis,most historical city pool sites were chosen between 0 °-3 °;History the city had no obvious dispositions to the downhill choice.2.The density distribution of the historical city spatially as a whole presents "" North MI,East Mi hydrophobic "",which has a positive correlation as the center of density distribution changed with the center of gravity of the ancient national population.3.The spatial structure formed by the distribution of the historical cities,in relation to the territories of the historical pilgrims in the area,whether it was a East-West linear structure,a north-south linear structure,or some other structure,varied with the territory of different pilgrims.4.The distribution state of the city,in addition to being associated with changes in territorial territory,was also associated with changes in the migration of both pilgrimage states.When closer to centralization,the first-order city was more strongly controlled than the second-order City,and the city pool distribution was more concentrated.By the mean distance,the changes in the control strength in the first-order ancient city fit well with the four major monophyletic systems in the formation and development of our ancient unified multi-ethnic country.The change in the distance between the city pools was characterized by four ups and falls in the Han,Sui,yuan and Qing to the valley,indicating greater control at all levels of the Georgia,and at this time also a time when the big unity was forming in our country.5.Natural factors such as temperature and slope had little influence on the spatial distribution of historical cities along the Yellow Region in Inner Mongolia,which was mainly influenced by political factors,and the direction of their distribution had a close relationship with regional variations.The influencing factors of the historical city distribution are mainly divided into natural and humanities factors.Natural factors mainly include temperature,slope,slope,elevation,etc.,and humanities factors mainly include politics,population,economy,ethnicity,transportation,etc.Through the research analysis of qualitative and quantitative between the influencing factors and the spatial distribution of the city,it was found that the natural factors had little influence on the overall spatial distribution of the historical city along the Yellow Region in Inner Mongolia,and the overall spatial distribution of the historical city was mainly influenced by political factors.Inner Mongolia has served as a stage for minority activity in the north since ancient times along the Yellow region,and the relationship between various nomadic groups in the north and the central dynasty is an important factor influencing historical city construction,as well as changes in the frontier areas in the north,affecting spatial distribution characteristics in the city space. |
