The Research On The Determination Of Beijing Metropolitan Area

Metropolitan area is a very important stage in today’s urban development. The importance of metropolitan areas is that it breaks out the scope of administrative divisions, not only by commuting changing space and scale urban development, but also to labor, capital flows across the region has brought great change. Many metropolitan areas from the perspective of the development world, metropolitan areas are becoming more and more countries attach importance to spatial scales of economic and social development. The city’s comprehensive carrying capacity study will help us better study urban development, at this stage of China into urban development model, to achieve sustainable development of great significance. For this reason, research in the perspective of comprehensive carrying capacity of urban metropolitan area is more conducive to an accurate assessment of the existing regional development, has important practical significance.Firstly, densely populated districts and counties of Beijing’s per GDP by description Yanqing, Miyun County in Beijing and there is a big gap between the average and commuting distance, long commuting time, if integrated in the calculation of the carrying capacity of Beijing Yanqing, Miyun, including Beijing clearly does not accurately reflect the current situation. In summing up the results of previous literature and theory on the basis of article compares the evolution of the metropolitan area of the United States and Japan, while taking into account the essential elements commute, we proposed a new method for defining metropolitan areas. In Beijing, for example, refer to the fifth census, the streets of Beijing, Hebei, Tianjin, three places, population density township, the proportion of agricultural population, the population growth rate during the sixth census and field visits, questionnaires " workers’ commuting distance, commute time, through the purchase of Beijing, Hebei, Tianjin and three accurate to street, GIS maps township, the use of GIS technology to determine the precise to the street in 2010, Beijing metropolitan area village, town range, and predict the range Beijing metropolitan area, this range has taken the administrative border.In the preliminary definition of metropolitan area of Beijing based on, combined with the existing Beijing urban rail transit planning, we found that Beijing existing traffic planning is focused on urban road network density increases, extent ignored the most urban commuter rail construction. The according to the Beijing metropolitan area development trend conceived four mostly urban commuter rail construction, draw the dynamic development of based on the Beijing metropolitan area, and with existing merely increase the internal road network density of urban planning based on the prediction of the metropolitan area of the ratio, it is found that the most urban commuter rail can indeed very good remission of Beijing urban problems and guide the Beijing rational expansion of urban space and economic sustainable development. The official metropolitan area as soon as possible a unified definition standards, actively building metropolitan commuter rail for Beijing Tianjin Hebei integration in response to the national call, has a very big role in promoting the promotion of regional development.
