The Population Spatial Distribution Change And Its Influencing Factors Research Of Jinan

Population is in a core about resource、ecology、environment and the sustainable development. The population spatial pattern is the result of geographical environment and social economy factors combined action. The distribution and evolution of population have regularity in a certain region. With promotion of the urbanization process rapidly, regional population space structure will be in dramatic change. Analysis city of the population distribution and change rule of Jinan, can help us to understanding of Jinan city status quo and development of the population, in addition, it s play a role of population for the promotion of social and economic development has important significance.This paper takes street region in Jinan as example,using national fifth and sixth census data, described the population distribution of Jinan.studied the population changes and growth differences,through the application of statistical software SPSS and geographic information systems software ArcGIS,Discussed the population spatial distribution change and its influencing factors Research of Jinan,This paper is divided into seven chapters, as follows:The first, explains the background and significance of this paper, and gives the foundation of choose the titlie and determines the thoughts、research methods、 contents and framework. Furthermore, gives the source of data used.Chapter two explains relative content of concepts thoughts and research scope.Chapter three uses census data to study the temporal-spatial evolution feature of population spatial distribution and internal discrepancy in Jinan since 1952.Results show that since 1952, Jinan population continues to increase, the district population’s average annual growth rate in 1970 and in 1990 appeared two peaks, and reach the population before 1990 annual growth rate higher than the average annual growth, annual growth rate is lower than the average annual growth rate since 1990.Chapter four With classic theoretical models of population density,it does model fitting of population distribution, results the specific model that meets the rule changes of population in Jinan.Fhidings:2000-2010, there is a large difference of the total population between Jinan’s streets. Population for the inner circle and the center of the fastest growing spheres of envelops, population growth is reduced, the core spheres of some streets of population quantity of absolute decline. Through the population trend surface fitting, found that over time, Jinan development towards more regularity of spatial distribution of population density, the direction of a more balanced evolution; During this period, the population center of gravity from northwest to southeast direction.Chapter five By adopting the population distribution model and spatial correlation analysis, explore the characteristics of population movement in Jinan.Research shows that:Jinan population spatial distribution is imbalance and the individual difference, high population density of blocks are mainly distributed in six areas of the city, outside the city streets significantly lower population density, street within the core spheres of population changes obviously. Outside the city’s high-high clustering area shrinking population to the cities within the circle and the center circle; Population low clustering are mainly distributed in the streets of core layers and inner circle, around the instructions within the city circle and the center circle of the population increase rapidly, the growth of population and the center circle inward spheres of faster than to the growth of the urban core spheres.Chapter six reveals influencing factors of population spatial distribution in Jinan.Natural environment, the better, the higher the level of economic development of the regional population increase, the more obvious. Found in the quantitative analysis, per capita GDP. GDP. mass proportion, secundiparity proportion, the proportion of tertiary industry, medical expenditure per capita, per capita expenditure on education is very important in influencing factors of population proportion. Among them, the per capita GDP is most obvious, and the influence of the factors affecting industrial structure, the tertiary industry proportion of the population density is the most sensitive, government spending on education, health care effect on population density increases gradually.Chapter seven summarizes research conclusions of this paper,and points out its shortcomings.
