Spatial Pattern And Evolution Of Hakka Population In Recent 60 Years

Taking the Ganmelong Hakka gathering area as an example,the 6 time sections of 1953,1962,1982,1990,2000 and 2010 were selected from the angles of unbalance,migration of population gravity center,spatial pattern of population density and spatial correlation analysis,and the area of county as the research unit and the gathering of Ganmeilong Hakka in the past 60 years was gathered.The basic characteristics of population spatial pattern evolution trend are analyzed.On the basis of the research results,the evolution mechanism of the factors affecting the spatial pattern of Ganmeilong Hakka gathering area is discussed based on principal component analysis.The results show that the population density of Ganmeilong Hakka gathering area has the spatial characteristics of "high north and south,low in the middle",and the population density is corresponding to the level of economic development.The imbalance of the population distribution in the Hakka gathering area of Ganmeilong is significant,and the overall trend of imbalance is first descending and then rising.The migration of the population center of gravity has the two characteristics of the overall stability,the intra group differentiation,the internal lightning type "(?)" migration,and the reverse migration of the population flow direction and the general migration of the whole country in the southeast.State.There is a certain spatial correlation in the population distribution of the Hakka gathering area of the Ganmeilong,and the Meizhou coastal county forms the agglomeration region with high spatial population density,and some inland counties of Ganzhou and Longyan form a concentrated area with low spatial population density,and the trend of population agglomeration first descends and then rises with the passage of time.Compared with other counties,the level of economic development is relatively high,which causes the region to attract the population to be collected continuously,and to form the characteristics of the high and low agglomeration of the surrounding areas.The county of high value and transition areas,because of its radiation range from the developed area,is low in radiation level,resulting in a low concentration of the surrounding regions,which appears obvious coastal.When the overall pattern remains relatively unchanged,some county units fall into high value agglomeration slightly,while low value agglomeration continues to grow.In recent years,the growth rate of population in inland areas has increased,the ability of gathering population has increased,while the ability of gathering in coastal areas has been weakened.The main factors affecting the evolution of the time and spatial pattern of the Hakka gathering area of the Ganmeilong are four aspects: the basis of the historical development,the level of economic development,the natural population growth and the policy of regional development.
