The Rational Land Development Of Strength Surrounding The Track Sites

With China’s sustained, rapid and healthy development of the economy, the degree of urbanization in the city continuously improve the expansion of city size, urban traffic pressure continues to rise. The problem is not just caused by traffic congestion, air pollution accompanied by deterioration of the road environment, urban development and other issues is not balanced.One way to solve traffic congestion in order to better alleviate the dual pressures of urban traffic and construction, to better adapt to the modern development, the construction of urban rail transit is an important way to solve the above problems, is currently the world’s major cities are trying.However, in practice there are still many problems to be solved, which tracks the rational development of land surrounding the site is a must face the problem of strength. Therefore, this paper based on rail transportation and land use interactions, starting from the classification of the track site and attract direct scope, analyze the impact of different factors on the development of strength in the use of land resources to achieve optimal conditions, the track surrounding the site land development intensity research.Comprehensive analysis of the current development of rail transit and land use relationships at home and abroad, mainly from the track site and surrounding land use developments on the two aspects of theory and practice, the research status of the two cross-cutting organize,summarize land surrounding the track site the development of the basic experience. Grasp the basic relationship between urban rail transit and land development, and to provide the necessary theoretical basis and practical basis for a research paper.In support of theoretical basis, through field investigation and analysis, classification and study of urban rail transit station site directly influence. Track combines Nanjing Line 1 South Extension and data, using principal component analysis to extract the relevant factors, the use of SPSS software to analyze the data obtained classify, track site will be divided into: general stations, transportation hubs, the city center station, times level central station, central station terminal five. Further investigation of urban rail transport services, directly affecting the scope of each type of site estimate. The resulting estimate of the track used by the site to attract unreasonable 600 m range, generally in the range of stations directly attract direct appeal directly to the range to attract the range of m, secondary central station directly m, the city center station m, transport hub to attract range In order to attract the range m, central station terminal is m.Again with the support of a large number of cases, the analysis of the impact of land use types of land development intensity, obtained orbit around the site intensity of land development and land use types are closely related, as land use, commercial, office space increases, land developmentintensity with The increase, while increasing residential land development intensity along slowly decrease. At the same time in the development process, the development of high-intensity plots also showed a tendency to gather in the hub; rail traffic impact analysis of land development intensity, draw down is recommended daily traffic intensity values at different sites around the land development; analysis of the impact of land development intensity track sites, combined with Taiwan, Hong Kong and comparative analysis of the rail system, the site location for the development of the role of strength, come recommended the development of different types of strength around the track site.According to the interaction between rail transit and land use to meet human social activity for the target maximum demand conditions, format and rail balance maximum carrying capacity constraints, the design simple linear optimization model to calculate the orbit within the scope of residential sites attract direct, office, commercial and other types of building development area.And, under certain assumptions, to simplify the model; and Nanjing rail line on the 3rd numerical example to verify the rationality and validity of the model.
