The Space-time Characteristics Of Population Distribution In Shaanxi Province And Its Suitability

Time and space distribution of population due to natural, historical, social,economic and policy factors, with diversity, complexity and comprehensive, isassociated with a variety of social relations of social entities. The population problemhas always is the focus in the study of human geography, is also an important issue intoday’s world development. For more than20years, Shaanxi province social economyalong with the development of the western region, great changes have taken place inthe national strategic measures such as population as necessary basis of socialproductivity development also changed significantly. Research in Shaanxi populationspatial and temporal distribution characteristics and evolution law of the status quoanalysis of the influence factors and rationality to fully grasp the populationdistribution pattern of time and space of the Shaanxi province and its variationcharacteristics is of great significance, thus to make reasonable regional populationpolicy, a reasonable redistribution of the population in Shanxi Province to providereliable basis, for the final realization of population, economy, resources andenvironment in Shanxi Province sustainable development foundation. Article USESthe index of spatial autocorrelation, population structure, population center of gravity,as well as migration-share analysis and other research methods, in Shaanxi provinceas the research unit, and some theory guilds97administrative region in1990-2000asthe research range, select population and population density as the research object,population in Shaanxi province was empty space time distribution characteristics andits rationality are described, and get the following conclusions:(1) in Shaanxiprovince population and population density spatial distribution is the pattern of"middle high-north and south low" characteristics, it is based on three major areas ofdifferent natural conditions and economic basis; In Shaanxi province populationdensity spatial distribution presents is spatial correlation, the populationagglomeration sex is stronger, to xi ’an as the center of the core region of guanzhongformed the high density of population gathering area, northern Shaanxi, due to theirsmall population base in southern Shaanxi, formed the population density of lowconcentrated area, while the guanzhong and northern Shaanxi, two large area oftransition zone formed at the county level administrative unit of high and low, high low concentrated area. With time integration trend slightly diminished. The imbalanceof the spatial distribution of population in Shaanxi province is more significant, trendrise.(2) Since1990, the center of gravity to the northeast of Shaanxi provincepopulation movement, movement speed is accelerated, with the northern Shaanxieconomy in recent years as a consequence of the rapid growth of Labour force growth.In northern Shaanxi, guanzhong, three big area population migration between growthand regional internal migration growth are rising, offset growth has obviousdifference among the three regions.(3) A reasonable population distribution in ShanxiProvince, but most of the smaller counties and cities population potential. Populationpotential larger counties and cities are mainly distributed in the southwest of QinbaMountain, the mountain basin, the guanzhong, most of the counties and cities insouthern Shaanxi population potential index is moderate, and population potential,smaller counties and cities are mainly distributed in northern Shaanxi area.
