Metropolitan Area Land Use Spatial Evolution Mechanism And Sustainable Development

The metropolitan district is the inexorable trend and stage that the urban and the region must be passed by, China is like this too. The Chinese minorities who live in the big city have already begun to move towards the suburb, China will welcome metropolitan district era soon. During the foreign metropolitan districts developing, because the unreasonable use of the metropolitan district land, it have caused the disorder of the structure of environment, society and resource. In our country the contradiction of the human-land is very conspicuous, how to arrange to the metropolitan district land use intensively and effectively is the great subject that will realize sustainable development in the future.From the interdynamic angle of the urban and region, regarding systematic methodology as thinking to support, using the theory and method of regional economic geography and urban geography, merging the thinking method and theory in other disciplines, such as ecology, sociology, economics, etc., on the basis of summarizing forefathers' research results, with the basic target of land utilize space key element, space structure and space form, This text sets up the comparatively intact theoretical system of the metropolitan district land utilizes space evolving, overall, systematically exposes the space evolving concept, type , course , mechanism , sustainable development of metropolitan district land utilizing, chooses the typical region of big city of our country -Changchun city for case of studying, proves to above-mentioned theoretical system, structures the control system of sustainable development of Changchun metropolitan district land utilizing space.The first part Mainly expound the evolving mechanism of themetropolitan district land utilizing space, includes three chapters: the concept and connotation space key element, form, structure evolving course, driving mechanism of the metropolitan district land utilizing space system.The metropolitan district is the space region type of the integrating between the urban and region after the city enters the suburb stage. The metropolitan district land utilizing space system behaves from three aspects: key element, structure and form, it has multiple land utilizing space characteristic of urban, region, urban and region.The key element space system of metropolitan district land utilizing represents from industry, agriculture, business, lives, the ecology and land using space of road, and divides the type of every key element in view of the above. The metropolitan district land utilizing space structure goes through three developing stages: the Center -Peripheral structure, Center city -Edge urban intergrowth structure, networked structure, and the space form goes through four developing stages: directional form with many axis, circle distributing form, main axis form, diamagnetism center combination form.The function factors of metropolitan district land utilizing space evolving mainly include the natural environment, upgrading of industrial structure, gathering effect, traffic technological innovation, planning adjustment and control, region culture. This text studies the function mechanism of the above-mentioned influence factor to space evolving to metropolitan district land utilizing from three aspects separately: function principle, function way, function mode.In the course of the foreign metropolitan district land utilizing space evolving, it have produced the negative effects, such as suburb spreading, center city declining, the pressure of resource and environment increasing continuously. The sustainable developmentof metropolitan district land utilizing space aims the unification with economy, society, environmental benefit, starts with encouraging the public transport, emphasizes the diversification of the land utilizing space and intensive use of land space resources, structures the develop model, builds the develop type in many space yardstick, such as area, cities and towns, urban area, etc., carries on the regulation and control of sustainable development f...
