Population Carrying Capacity Study On Capital City

Lanzhou is the capital city of Gansu Province since the founding of the national attentionto the construction of the industrial system in Gansu Province, Gansu Province, will initiallybuild a relatively complete industrial system, one of the provinces, and by virtue of theYellow River in Lanzhou City, the waters of the Northwest ’s traffic arteries leading to andadvantage of the social and cultural center of the intersection, the majority of military andcivilian manufacturing companies attracted to Maryland to settle down, but in recent years,economic, social, urban construction Lanzhou rapid development, but also the developmentand population, resources and environment conflicts sharper period. For Maryland, on onehand facing a huge population, while also facing restrictions on land resources, waterresources, etc.. Therefore, current research and future Lanzhou population carrying capacityis very important for the future of the capital city to play better features and aspects ofpopulation carrying capacity to solve existing problems and enhance the development ofspace Lanzhou population carrying capacity has some significance.In this paper, based on the theory of resource scarcity, sustainable theory, short platetheory development, using the latest data, combined with the level of socio-economicdevelopment of the existing and future population Lanzhou development trend, integratedLanzhou municipal government on recent economic and social development plans andlong-term goals from the scale of development of cities and abroad starting, qualitativeanalysis and quantitative calculated combining departure from the system integrity, build acomprehensive framework and population carrying capacity index system Lanzhoupopulation, economy, society, resources and ecological development of were able to analyzethe main limiting factors restricting the development of Lanzhou population, based on the useof "differential drive " the principle of empowering law-entropy method and linear weightedsynthetic method (SAW) method to determine the combination of primary and secondaryindicators index weights, which estimates the population carrying capacity of Lanzhou City,economy, society, resources, ecological four sub-systems, and integrated population carryingcapacity between2000-2011, and hosted by comparison with the actual situation of thepopulation, drawn Lanzhou population carrying capacity. The results showed that:①Lanzhou Economic and ecological carrying population carrying the opposite demographic trends, including economic carrying population increasing trend;②Lanzhou populationbetween2004-2010are overloaded state, and decreasing population size overload;③environment comprehensive population Carrying Capacity constraints are always a majorbottleneck in Lanzhou, non-sustainable economic and social development of the total typefrom population, resources, policies, legal and other aspects of the industrial structure toalleviate pressure on the population carrying Lanzhou policy recommendations for LanzhouCity offers strategies to improve the population carrying capacity.
