| In this paper,the urban human settlement is both a complex giant system and an organic life body,at the same time,it is the key to the development and progress of the society,however,almost all geographical phenomena and things follow the Life-Cycle theory,in the process of its dynamic evolution,such as growth,development,shrinkage and extinction,many diseases and many problems are inevitable,the Northeast China is no exception,the loss of the population,the environmental pollution,the bankruptcy of the enterprises,the exhaustion of resources,the serious stock of real estate,the decline of economic growth and so on,etc.In essence,these are both the external disease of the urban human settlements and the inevitability of the temporal and spatial evolution of the urban human settlements.Cognition and research on the temporal and spatial evolution law of urban reality and pseudo human settlements;it has the theoretical exploration value of "The sciences of human settlements"," human settlements pathobiology","new man-land relationship" and "new space-time concept".At the same time,it also has the society practical service value of "the Manchurian Mandate","“the construction of ecological civilization",and the cognitive"imbalanced and inadequate" contradiction and so on.Through the open source interface of the Baidu index(http://index.baidu.com),a total of 2192 days from January 1,2011 to December 31,2016,10 subsystems such as communication and social networking,32 sub elements,such as micro-blog,Jingdong and so on,a total of 2525184 pieces of data were collected in 36 prefecture level cities Northeast China,and a database of urban pseudo human settlements has been set up.Through socioeconomic data,census data,and corresponding graphic data,26 indicators such as the proportion of non agricultural population to the total population,5 systems such as the human system,were collected for 2002-2016 for 15 years,and a database of urban reality human settlements has been set up.The phenomenon of "development and shrinkage" in the evolution of urban human settlement is revealed.Data mining analysis,geographic information technology(GIS),quantitative geography(entropy etc.)are used to analysis hierarchical system,the process of temporal evolution,the process of the spatial evolution,temporal and spatial evolution characteristics of development and contraction of urban reality human settlements and urban pseudo human settlements,the special effects of the spatio-temporal evolution of urban pseudo human settlements.The six ways of spatial and temporal evolution of urban human settlements are preliminarily considered.The contrastive relationship,apocalypse and practical application of urban reality human settlements and urban pseudo human settlements are discussed,and the "three states" of the urban human settlements(urban reality human settlements,urban pseudo human settlements,urban imagery human settlements)is prospected.Big data,we-media,information space and computer technology provide new ideas,new opportunities and new paradigms for the study of human settlement in the perspective of geography,however,in the future,traditional data will not lose its academic value for a long time.The information data and the traditional data are combined,and the urban reality human settlements are unified with urban pseudo human settlements,the diversification of human settlements in the tide of information and globalization has the academic significance of epistemology and the value of social service at the practical level.The preliminary results are shown as follows:(1)The hierarchical system urban reality and pseudo human settlements.1)Primary index.Whether it is the urban reality human settlements or urban pseudo human settlements,in the process of its evolution,there are obvious first primary index characteristics and a perfect hierarchy,however,in these aspects,such as the representative cities of primary index and the permutation and combination of urban hierarchy,the two human settlements are different.2)Variability.The rankings change of in the front and back of urban reality human settlements and urban pseudo human settlements are not very obvious and more stable,but the changes in the middle of the rankings are more obvious.3)Agglomeration.Whether the urban reality human settlements or urban pseudo human settlements,two of them have the attribute of spatial agglomeration,Shenyang Dalian agglomeration core area,Changchun Jilin agglomeration core area and Harbin Daqing agglomeration core area are the two common attributes of urban reality human settlements or urban pseudo human settlements.(2)The process of temporal evolution of urban reality human settlements and urban pseudo human settlements.1)The unity of overall trend,whether the urban reality human settlements or urban pseudo human settlements,the main melody of the two time evolution process is still development,there is also a shrinkage phenomenon in the two,the particular year node of development and shrinkage are different,and the number of development and shrinkage of cities are also different.For the urban reality human settlements,the maximum point of development was 2007,and the maximum point of shrinkage was 2014,for the urban pseudo human settlements,the year of high development was in 2016,and the representative year of severe shrinkage was in 2012.2)The difference of temporal evolution.For the urban pseudo human settlements,the number of development cities shows an obvious trend of growth,and the number of shrinkage cities shows a significant downward trend.For the urban reality human settlements,the number of development and shrinkage cities showing a more obvious alternate evolution trend.3)The unity and difference of time type.The urban reality human settlements and the urban pseudo human settlements are composed of two main categories:the urban human settlements development and the urban human settlements shrinkage,but because of the difference in time,space and scale,the subcategories of development and shrinkage are different.(3)The process of the spatial evolution of urban reality human settlements and urban pseudo human settlements.1)The unity and difference of the regional typical characteristics,based on the criteria of "overall development","overall shrinkage ","development period","shrinkage period","development point" and "shrinkage point" of urban real human settlements,the evolution of urban human settlements are divided into eight different types,however,due to the limitation of the time scale of research,the classification of urban pseudo human settlements are only six categories.2)The difference in the characteristics of temporal and spatial evolution,The characteristics of the overall temporal and spatial evolution of the urban pseudo human settlements are from shrinkage to development,although the urban reality human settlements is still developing in general,the development zone,the shrinkage zone,the development point and the shrinkage point appear alternately.3)The unity and difference of the evolution of the typical cities human settlements.The unity,the urban reality human settlements and urban pseudo human settlements all have a continuous getting better and continuous decline in the development level,at the shrinkage level,the two all have the situation that the shrinkage is aggravated and the shrinkage is gradually reduced,there are quantitative and qualitative changes in both development and contraction.The difference,the urban reality human settlements is in the process of evolution,the isolated development and shrinkage point can cause the overall development or shrinkage within a certain period of time.In the case of overall development and overall shrinkage,there will be a period of development and overall shrinkage,at these two levels,the urban human pseudo settlements is a subset of the evolution of urban reality human settlements.(4)The six ways of spatial and temporal evolution of urban human settlements.The urban human settlements is a complex giant system and is also a dynamic evolution organic life,with the evolution of "subject" and "object","system" and "element","structure" and"function",The urban human settlements takes "time","space" and "scale" as the criterion,a numerous and complicated evolution will going to happen.It is preliminarily believed that there are six possibilities for the evolution of urban human settlements:The absolute evolution of urban human settlements;The relative evolution of urban human settlements;The subject evolution of urban human settlements;The evolution of urban pseudo human settlements;The evolution of urban reality/pseudo human settlements;The evolution of urban"three states" of human settlements.(5)The relevance,special effect,apocalypse and practical application of urban reality human settlements and urban pseudo human settlements,the overall interdependency between the urban reality human settlements and urban pseudo human settlements is relatively large,there are significant differences in the correlation between different provinces,and the correlation between different types of cities is more significant.Urban pseudo human settlements have more obvious characteristics of primary index and dispersion characteristics than urban eality human settlements.Whether the "double eleven effect"of the shopping type of urban pseudo human settlements,the "precursor effect"of the tourism type of urban pseudo human settlements or the "Friday and Saturday effect"of the group purchase type of urban pseudo human settlements,in essence,it is the representation of the urban pseudo human settlements in the process of evolution,in a certain period of time and in a certain spatial,the reality or pseudo geographic phenomenon is gathering and then shrinking.The apocalypse,the widening of the research category of human settlements is conducive to the promotion of the construction of human settlements;the continuous deepening of the content of human settlements is easy to cope with the increasingly complex urban environment problems;The constant change in the thinking of human settlements helps to adapt to the human settlements changing.The practical application,urban construction has shifted from "livable city" to"livable wisdom city";urban services has shifted from from "real space" to "real and pseudo space";urban management has shifted from from "static" to "static,dynamic and early warning".(6)The inadequacies and future research exploration direction.The inadequacies,the spatial and temporal scale of the urban reality human settlements and urban pseudo human settlements data is not equal,failure to make a comparison of the urban reality and pseudo human settlements based on the subjective residents,The part of the theory of temporal and spatial evolution of human settlements is lack of empirical research.The future research exploration direction,Combining network data with traditional data,the integration of the whole society with the individual,the combination of the "three states" urban human settlements,in order to meet the needs of the reality,serve the vision of a society. |
