Studing And Evaluation Land Use Intensivcation In Urban Area In Case Of Taiyuan

At present, our country is pushing the stage of accelerated development industrialization, urbanization and modernization. It need to increase large amount of construction land, while, the conditions that our country has large population with relatively little land ,so it is inadmissibility to occupy cultivated land more than required, land resources shortage already becomes a main part restricting a factor of our country economic growth. So, how to make good use of land, especially urban land becomes a problem to be dealt with urgently. Our country's current situation of land utilization requires that we must change the land utilization from extensive to intensive forth, optimize the utilization structure of urban land , improve the utilization efficiency of urban land, dyadic the utilization potential of urban land , walk a development road of connotation style .The urban land means the land in the city range inner. According to the different definition of our country city range boundary, urban land contains three kinds of concepts, the land of build district, urban planning land and urban city region land. The land is point to the land in the city range inner and the construction land expropriated in the build district because of country construction need in the process of the city construction.Urban land is the most assembling region of human activities, so making good intensive use of urban land has important significance to social development. In fact, Urban land intensive utilization is a management and administration pattern,. that put the thought that urban land lay out rational, optimize with the land structure and sustainable development as the guide, by increasing storing amounts land approach and improving management and administration and so on, to improve the use efficiency and the economic effect. Urban land intensive utilization study mainly rational of the intensity degree in urban land exploitation and utilization, putting particular emphasis on digging the potential of urban land utilization .Urban land intensive utilization is the basis that urban land use keep continues and high-effect, and the guarantee that urban land health develops.This paper starts from studying the current situation in urban land utilization in our country, then carry out a summary and expounds deeply the theory about urban land intensive at home and abroad, after that, make sure the concept and connotation of urban land intensive, then from the angle of society, economy, the ecological environment ,construct a urban land appraise index system, take city land synthesis intensive as target tier, take quantity intensive, space structure intensive, development intensive as criterion tier, evaluate urban economic effect in inner scale and so on by choosing the corresponding index factor, in this process, it has adopt AHP method to build the judging matrix in order to certain the weight of the index.This paper take Tai Yuan City as a demonstration, at first, It chooses Shijiazhuang, Baotou, Tangshan ect ten equal types city in the whole country range, applies Multi-objective synthetically evaluation method and model to intensive evaluation in comparison on these cities, as a result, Tai Yuan City is in medium intensive level in these the same type cities in the whole country. And then analyses of the annual Tai Yuan City society economic statistics data and land utilization data from 2000 to 2004 year, appraise estimates and analyses the situation of urban land utilization in Taiyuan according to the system of urban land quantization evaluation constructed, get a result that Tai Yuan City land utilization structure is basically rational, at present, and land utilization towards to intensive direction grows beneficially, meanwhile, it has lower level in urban land throw into with and society organism's beneficial, and give some suggestions and measures that land utilization from now on in reality .
