The Research Of Several Problems About Metro Train Depot Air-rights Development

Urban rapid rail transit(URRT)plays an active and key role to relieve urban traffic congestions,improve the surrounding property values,expand the urban development space,and enhance land development intensity.As the rapid development of URRT,it faced questions with the shortage of funds of construction investment and operation cost.Havin the big area,low intensity of land utilization,single function,and relatively independent to the surrounding environment,traditional train depot become the new segmentation medium of city,which is not good for the intensive use of urban land.The comprehensive utilization of train depot,is not only beneficial to earning the profit of property development but also to the intensive use of urban land.Therefor the research of train depot air-rights development theory basis,the land-use right,pollution control,financial analysis,has practical significance and application value.Based on the research of transit-oriented development(TOD)at home and abroad,according to passenger flow of the guangzhou metro network operating characteristics,paper put forward guangzhou metro development strategy by using SWOT analysis.It should give priority to service-oriented development(SOD)to meet traffic demand in urban;And it should give priority to TOD in suburb to carry out the mixed land-used development surrounding station by improving region accessibility,accelerating the regional development,attracting the residents in urban,which can obtain considerable economic benefit and feed URRT construction cost.Using the stakeholder theory,Paper made a research on the land development of guangzhou metro train depot,and proposed the confirmation of layered land-space rights.The use-right of train depot interspace is allotted to URRT construction unit,while the air-rights of train depot need to be obtained by paid way such as assignment approach or land leasing bid auction.By analyzing the function,characteristics and pollution sources of B train depot air-rights development,Paper designed total plane layout,interface management and traffic organization of the B train depot and cover property,and established environmental protection measures to reduce influence between the train depot and cover property such as reducing vibration and noise.Using the Analytic Hierarchy Process(AHP)to analyze real estate pricing,paper established evaluation system and the judgment matrix,figured out the estate price in 24368 yuan per sqm,and according to the guangzhou housing price growth rate of 40% from 2010 and 2015,forecasted the price in 2021 will rise to 34115 yuan per sqm,which of key factors was the regional factors,product features and public supporting facilities.According to the project capital outflow and inflow analysis,the project has good financial benefits,showed upon the land leasing income is 5.08501 billion yuan,static land profit margins of 187%,air-rights development project financial net present value(FNPV)is 5.59626 billion yuan,internal rate of return(IRR)is 12%,investment return period is 3.08 years.The study can provide the reference ways and means for future similar engineering construction.
