Urban Comprehensive Carrying Capacity Evaluation Of Economic Belt Of Tianshan North-slope

With the rapid development of urbanization, the world is faced with the problems such as environmental pollution, resource shortage, traffic congestion and so on, which have tended to the key factors restricting the security and sustainable development of the regional areas and the nation. The urban comprehensive carrying capacity is an important basis to measure the ability of sustainable development, furthermore, the gradual improvement of it is a necessity to realize sustainable development. Improving urban comprehensive carrying capacity and realizing of sustainable development, not only contributes to the development of the city, but also the overall progress of peri-urban areas.Economic belt of Tianshan North-slope is the core region and the most important growth pole of the national economic and social development in Xinjiang. It is also the focus of the West Development. In recent years, with the promotion of West development policy and counterpart supporting policy, Economic belt of Tianshan North-slope becomes the concentration area of population distribution, resource depletion and environmental pollution. Studying the urban comprehensive carrying capacity of Economic belt of Tianshan North-slope and promoting its sustainable development are the need of West Development strategy’s promotion, thus have far-reaching realistic meaning and substantial research value.Researching on the seven core cities of Economic belt of Tianshan North-slope, this essay establishes comprehensive evaluation index system into six dimensions: land, water, transportation, environment, population and economy. The index weight is evaluated by multi-indicator synthetic analysis and standard deviation decision. The urban comprehensive carrying capacity is evaluated and analyzed by TOPSIS model. The purpose of the study is to find effective measures to improve the Economic belt of Tianshan North-slope and promote its sustainable development.Based on the general situation of the urban carrying capacity of the economic belt of Tianshan North-slope, according to the principles of constructing index system, together identifying the index weight with the method of mean-squared deviation, this essay finally establishes the model of the urban comprehensive carrying capacity--TOPSIS model. Then the thesis carries on measurement and comparative analysis of the urban carrying capacity of the economic belt of Tianshan North-slope based on the model constructed and the effective statistics, mainly involves comparative analysis of the cities’ comprehensive carrying capacity of the economic belt of Tianshan North-slope and the analysis of the comprehensive carrying capacity of the economic belt of Tianshan North-slope effectively through comparative analysis of annual variation of the cities and the analysis of the comprehensive carrying capacity of the economic belt of Tianshan North-slope. Eventually, the thesis makes suggestions about improving the urban comprehensive carrying capacity of economic belt of Tianshan North-slope based on the outcome of the empirical research which comes in the two perspectives of different cities and economic belt of Tianshan North-slope and the six respects of land, water, traffic, environment, population and economic.
