City Spread And Rational Growth

China’s reform and opening up30years with the gradual improvement and progress of social economy, our country has gradually entered the high-speed development period of urbanization, urban space is in constant expansion, the population density of city continues to decline, presented the development trend of the spread. Therefore, developing a series of financial problems, social problems and environmental problems. City is spread of urban development in the form of random rate, unable to control to the surrounding areas of continuous expansion, as a kind of low density, and could not continue, to rely on car travel, the development of residential and non-residential construction mode, is constantly a large number of agricultural land and social consumption at the expense of natural resources, serious damage to the environment, economy and society and so on various aspects of interests, brought new influence to the urban space structure, so that the environmental, economic, and social and so on various aspects of the interest suffered serious damage, to the benign development of the urban space structure has brought bad influence, lead to urban form a new change. Now China is in the process of high-speed urbanization, the spread of malignant growth and city are common in many cities, the urban problems become increasingly serious. Blind expansion, shortage of resources, such as city proper embezzled a large number of farmland and natural land, land waste, environmental degradation and low density development, traffic congestion, the old city transformation and the construction of infrastructure and urban public services lag, transportation costs increase, the continually rising house prices, the rising cost of living and business separation, and so on many problems, which affected the urban residents living environment quality decline and a variety of urban security problems. If the "aggressive" and space of the severe situation of urbanization can’t effectively stop, will be seriously hinder the whole development process of our modernization. In this context, this article through the spread of economic development, urban ecological environment and the influence of social life. Affirmation of the positive impact of spread to the urban economic development, the quality of social existence in social life of the masses have a certain role in promoting, analyze and criticize the city spread of the negative effects on the social environment, points out that the urban spread of cultivated land resources, the wetland resources, energy resources and groundwater resources enormous waste and consumption unceasingly, is one of the main resistance for the sustainable development of urbanization. On the basis of an analysis of the concept of rational growth, through draw lessons from foreign mature theory of mature theory to control the spread of city and urban land and urban land spread the status quo of research both at home and abroad, fully analyzed the spread the same and different parts of the domestic and foreign cities, using the city spread and the theoretical framework to analyze urban spread of rational growth problems in the process of land use, urban boundary spread unceasingly, perfect evaluation system and conduct an empirical analysis to explain the reason of the spread of cities, effect and countermeasure, through to the Beijing urban development and the surrounding areas of practice and study and finally to put forward the protective planning and control measures of urban spread and draw conclusions. Urged by the geographic information system and other advanced technology to innovation and innovation management, governance means establishing land development rights transfer mechanism, optimize the rational allocation of land resources, to realize the smart growth innovation city development pattern. Practice shows that the rational urban growth model can make the government’s investment in infrastructure greatly reduced, reduces the cost of living, optimize the structure of urban land use, land asset disposal policy through flexible, will be part of the economic benefit is poor, backward technology and equipment of the enterprise out of the city center, in the original enterprise covers an area of high benefit, high technology, the development and construction of environmental protection, realize the city industrial structure adjustment and the two aspects of land use structure optimization at the same time, both regenerate the land assets, and promote the adjustment of the urban structure and economic layout, improve the urban comprehensive competition ability. In addition, the government should also change the structure of function, must have a good market order, as the premise of optimizing the allocation of urban land resources. Abandon the excessive intervention in the market. By real estate registration system, real estate transaction procedures and rules, land use planning, urban planning, real estate information disclosure system and a series of strengthening the effective control of the land market, establish the order of land market norms. Land resources is the basis of economic development in our country, urban land use is more closely associated with economic development. Extensive mode of economic growth in China for a long time due to the use of land resources of high consumption, low output, huge waste, rigid constraints of urban land resources supply, so we have to constantly improve the land utilization, scientific and reasonable, economical and intensive land use, to the road of sustainable development. The innovation of the article is to scientifically partition use of land.
