With China's sustained and rapid economic development， the accelerating process of urbanization， China's urban rail transit construction has entered a rapid development Urban rail transit is to promote urban economic development， improve the urban ecological environment， optimize the urban structure， the key to achieving sustainable urban We track the traffic the site is divided into residential-type， central hub and three categories， combined with the widely used abroad TOD model， classification of the regional rail transit site development intensity and spatial distribution， and rail traffic on the surrounding economy of On this basis， Huadu， Guangzhou Metro Line 9 to the site to set the initial planning studies， and its economic impact on the Huadu District of major 如果是论文的摘要翻译的话，不用太较真差不多就行没人会仔细看祝你好运~
The orbital transportation has the capacity to be big， speed quick， safe， punctual and so on a series of merits， to alleviates the municipal transportation pressure， to guide the urban space development， to adjust the urban land layout， to improve the urban environment quality， and the promotion urbanization advancement may play the tremendous Therefore， facing our country urban development's specific stage， studies the orbital transportation plan wire the construction succession to have the very vital practical This article first analyzes the world typical city the orbital transportation development process， and will unify our country track transport facilities present situation and near future plan， proposed that our country city track transport facilities present existence's subject matter， and to will affect the orbital plan wire construction succession the correlation factor to carry on the analysis， based on this from the construction opportunity， the construction scale and the construction order three aspects will conduct the research to the track transport facilities succession's definite The orbital transportation construction opportunity's determination uses conventional the cost benefit analysis， adopts in the influencing factor the urban population scale and the economic level (each person of average income) two important targets carries on the quantification The construction target is defined as income - population standardization target IPN， in the mean time gap value's IPN target may think that is the suitable time， simultaneously is lower than and is higher than this standard value time selection to consider separately corresponding premature and the excessively late time The track transport facilities scale's determination divides into the start time， the centralism construction period and the consummation time three The start time is mainly through the quality synthetic evaluation system determined that initial period construction scale to be whether The centralized construction period increases through the expectation orbital transportation proportion with the expectation compact car journey proportion reduces， the orbital wire's level， the structure and the combination as well as the urban space shape and the layout structure determine the construction scale， recombination urban economy bearing capacity， makes the suitable adjustment and the The perfect time is mainly the wire encryption as well as the city territory line construction， the union satellite town or the suburb development special details and the urban developmental strategy， adopts “the passenger flow demand” and “the guidance demand” carries on the This article determines “the first line， the skeleton wire， the development wire and the auxiliary wire” such orbital wire construction The orbital transportation's first line often is passes through the city large-scale transport hub， the business center and the crowded housing employement center main transportation The skeleton wire interior line construction successively produces differently the effect is different， we may determine its priority through the benefit maximization Development wire and when auxiliary wire construction should pay attention to TOD and the SOD union， according to passenger flow size and development guidance emergency possible arrangement construction 城市轨道交通、Urban track transportation规划线网、plan wire建设时机、construction opportunity建设规模、construction scale建设顺序construction order
