Evaluation And Research On Carrying Capacity Of Urban Infrastructure Of Northern Slope Of Tianshan Urban Agglomerations

Urban infrastructure is an important material foundation of a city, it’s an important material guarantee of people’s the living and economic development, it’s an important manifestation of the level of urban development, hardware & software investment environment and the city’s comprehensive competitiveness. Sound infrastructure is an important factor in promoting urban economic development, poor infrastructure will restrict urban economic development.Xinjiang as the core area of building “OBAOR”, will become an important regional transport hub, energy major thoroughfare, the new Eurasian Continental Bridge. This means that Xinjiang will construct large-scale infrastructure. Against this background, Select Northern Slope of Tianshan Urban Agglomerations as research subjects, which is the forefront and most representative region in Xinjiang, to research the problems and carrying capacity and carrying state of Xinjiang infrastructure. Combined with infrastructure-related theory, choose transportation, water supply, energy supply, communications and environmental health a total of five-level indicators and 14 secondary indicators, to build evaluation system of Northern Slope of Tianshan Urban Agglomerations infrastructure carrying capacity. Research and analysis from the three levels, First, to analyze the status of the northern slope of Tianshan urban cluster infrastructure,by comparison with the reference area, found the problems and shortcomings;Second, the introduction of the concept of "carrying capacity", and on the northern slope of Tianshan urban cluster infrastructure carrying capacity of each city is estimated using principal component analysis, synthesis indicators were given scores of cities, it aims to explore the Tianshan Mountains Cities the difference between the bearing capacity between infrastructure; Third, reference the “research methods of relatively Resources", select the national average as a reference section, from the time the longitudinal direction to analyze the northern slope of Tianshan urban cluster infrastructure bearer status. The study found:(1) northern slope of Tianshan urban cluster infrastructure carrying capacity in a sustained upward trend, but between the Tianshan Mountains city urban infrastructure carrying capacity of each group in an unbalanced state, showing large cities, industrial city better than small cities, the city of phenomenon. Among them, the infrastructure carrying capacity is the highest index in Urumqi and Karamay, Changji City and followed Shihezi City, the lowest in Kuitun City, Fukang City and Wusu.(2) From the time the longitudinal analysis, the Tianshan Mountains infrastructure carrying capacity of urban agglomeration in 1990-during 2012 in a rising trend. Cities during this period increased from 71.89 tons per capita water / year rose to 731.45 tons / year; the total postal and telecommunications services from 18.94 yuan per capita increased to 1321.78 yuan; urban per capita public green area from 6.35 square meters increased to 9.8 m2; In addition, city 31.39 cubic meters per capita by the gas volume increased to 193.53 m3 only nine years, average annual growth of 57.4 percent. Cities northern slope of Tianshan urban infrastructure carrying capacity has been significantly improved.(3) compared to a reference area, we found that in addition by policy factors, 2000-2001 and 2011-2012 two periods northern slope of Tianshan urban cluster infrastructure carrying capacity better than the reference level area, the rest were lower than the reference level area. Overall, the northern slope of Tianshan urban cluster infrastructure carrying capacity can not effectively meet the needs of economic and social development, and in most years in the "overload" state. Finally, the article suggests should begin to coordinate infrastructure construction and economic development of relations, handling the relationship between infrastructure and environmental benefits, rational planning, strengthen supervision and improve the legal system, while proactive policy to seize opportunities and other aspects, to further improve the Tianshan North Slope infrastructure carrying capacity of urban agglomeration.This paper is divided into seven parts, the first part is an introduction, describes the research background, significance, research status and research content, method, technique route. The second part of the relevant concepts defined connotation, basic theory and infrastructure evaluation methods are introduced. The third part is analyzes the development of urban agglomeration infrastructure of Tianshan Mountains and summarize the existing problems. The fourth part is builds infrastructure carrying capacity evaluation system of the northern slope of Tianshan urban agglomeration. The fifth part is calculates infrastructure carrying capacity index of the northern slope of Tianshan urban agglomeration. The sixth part is evaluates infrastructure carrying capacity of the northern slope of Tianshan urban agglomeration. Make relevant suggestions at last part.
