Based On The Green Transportation,constructed Low-carbon Hub

The rapid development of modern city and highly gathered population caused environmental pollution, chaos space and traffic jams. Improving the operation efficiency of traffic system can obtain the good results of energy conservation and emissions reduction. .The advantage of low carbonation of high-speed rail becomes the first choice to solve the problems of city and traffic.The large-scale high iron hub construction tasks which were brought by the rapid development of high-speed railway need forward-looking theory guidance. High speed rail traffic is the key nodes of building network green hub. Through the low carbon type high iron hub intervention can improve the urban transportation system and the operation efficiency of urban space structure, and can accord with the essence of urban sustainable development needs. Therefore, the starting point of the paper is constructing "green traffic", and the main research of the paper is the low carbon type high iron hub. We discussed the low carbon type high iron hub's key elements which based on the concept of green transportation; constructed the researching system of low carbon type high iron hub plan design; put forward the design strategy of systematic low carbon type high iron hub plan; looked forward the low carbon type with the construction of high iron hub conception which complied the Chinese Circumstance.In the paper we borrowed ideas from green traffic concept; analyzed the changing towards the railway hub and the high-speed railway's development of the high iron hub and the basic mode; put forward the necessity and essence of construction of low carbon type high iron hub. We divided the paper into three parts to reach the principles and functions of systematic low carbonization strategy.Firstly, low carbon type high iron hub's overall planning must implement systematic view of environment. We can choose suitable guidance according to the systematic conception of environmental protection and we can location scheme rationalization according to the evaluation system and environment influence the involvement of model. We should guide the hub area of traffic organization according to the energy-saving principle; and guide function layout under system environment view; emphasize the intensive land utilization , convenient an d efficient transfer mode, appropriate measure , entrances position of planning.Secondly, the low carbon type high iron hub external space form the core elements of planning design of urban space is city's coordination and symbiosis. We should realize the continuation of and respect, and design from the whole pattern of the city.Third, high efficient and low-energy would be looked as the organizational principles of internal space. We should emphasize the efficient transport space and humanized layout commercial space, increase the development and utilization of underground space, realize energy saving and emission reduction targets according to the efficient and the spatial organization ways.In the paper, according to the examples of the representative high iron hub in the different social background, we constructed the three different development patterns to compare. The purpose of the paper is constructing an evaluation system of generality low carbon type high iron hub'. And at last I was thinking over about the strategy of constructing the suitable low carbonization high iron hub in our country.
