Research On Sustainable Development Between Population And Economic Society Of Liangzhou District

Population, the basis of coordinated development between a nation and regional economy, resources and environment, is the core issue of sustainable development. With the rapid population growth, social activities as well as economic activities created by human beings are getting drastic as never before, and the relationship between human and nature has gradually become imbalance. The relationship between population and economic development plays as a key to regional sustainable development, which explains the reason why it attracts great attention from geography, economy as well as demology. The number, structure and cultural quality of population, is not only an important basis for planning regional economy and social development, but also important content to be studied by medium and long term planning. Controlling population growth, adjusting population structure and improving population quality are important guarantee for the coordination of development between population and socio-economy.Wuwei is the typical Oasis city in Hexi corridor of Gansu province, and Liangzhou District is in the middle reaches of Shiyang River Basin. It is the first major water consumer as well as the most populous district in Gansu province. The primary industry occupies a higher proportion in Liangzhou District, while output growth are mainly at the cost of exhaustion of resources, the contradiction between population growth and resource exhaustion has become more and more prominent. Its trend of population changes will directly affect the socio-economic goals in the District, and even influence the sustainable development of the entire Shiyang River Basin.From the perspective of population's impact on economic development, this paper took comprehensive studies on population and socio-economic development of Liangzhou District of Wuwei City from 2000 to 2005 by method of looking up statistical data, necessary investigation and analysis as well as multi-level data processing and research. It analyzed the connection between population and socio-economic development based on various economic index, together with population and economic development of Liangzhou District of Wuwei City from 2000-2005, according to the Fifth National Census data of Liangzhou District, using population prediction software (CPPS), this paper also predicted the trend of population development before 2050, and analyzed the possible social influence as well as studied corresponding strategies and emphasis.Following contents are included in this essay:Part II: The basic theory of population and economic and social development;Part III: The current population situation of Liangzhou District; it explores the quantitative changes of population development, population distribution and its structure, population floating and its quality composition.Part IV: It discusses the economic capacity per capita, financial income and expenditure per capita, income per capita and consumption level of urban and rural residents, fixed assets investment per capita, infrastructure development per capita of Liangzhou District , and finds out that there is potential contradiction between population and economic capacity although the income and consumption level, fixed assets investment and infrastructure conditions have been improved.Part V: The demographic trends from 2006 to 2050 and their impact on society of Liangzhou District; it turns out that the elderly population coefficient goes up gently from 2006 to 2026, while the working age population from 15 to 64 keeps a proportion of 70% in the total population, which is the period of the smallest population burden coefficient. From 2027 to 2039, the elderly population coefficient will increase sharply at the speed of 5.72%each year, and the elderly population will reach 265,500 people and the elderly population coefficient will be as high as 57.10%. After 2040, the population development is basically stable at an average annual growth rate of 0.25%. Besides, the sex ratio of from 2010 to 2050 takes on apparently a upward trend.Part VI: Through analysis of current situation of population development and population prediction, it reaches the problems existed and puts forward specific countermeasures.
