| In the world, the change of the mode of transportation has a very important influence on the social productivity, the benefit of land use and the way of human travel. Owing to it’s advantages of large traffic volume and high speed, The railway has become the most important means of transportation in the world, and it has a great influence on all aspects of human life. Under the background of "The Belt and Road" strategy, this paper choices the main cities and its surrounding areas along the railway Boten to Vientiane in Laos as the research objects. With the viewpoint of the traffic impact on the land value-added potential, the paper estimates the land value-added potential of three tourist cities and the value added spatial distribution pattern of the built-up area of four node cities along the railway with the influence of the railway construction. The purpose of study is to provide reference for the investment individuals or organizations.On the basis of comprehensive consideration of the natural location, traffic location and economic location, by determining the evaluation index, dividing the evaluation units and other steps to establish the evaluation system, the author evaluates the potential of the surrounding land of Luang Prabang, VangVieng and Vientiane, which are the tourism cities along the railway, when the railway will be completed in 2020. And makes the land value-added potential and spatial distribution map of peripheral tourism radiation areas of each node city. According to the evaluation results, investors can make a reasonable commercial investment plan. Investors can invest in the tourism related facilities and tourism real estate projects in the higher land value-added potential mass where closed to scenic spot.In addition, adopting spatial statistics and neural network model simulation method, this paper studys the spatial distribution of land price of the four node cities of Muang xay, Luang Prabang, VangVieng, Vientiane in 2014 and the land value-added potential of the four node cities,when the railway will be completed in 2020. The results are as follows:(1) In 2014, from low to high,the sort of the land price of four node cities is Muang xay, VangVieng, Luang Prabang and Vientiane. The price of land in each city shows a clear single center spatial distribution pattern with CBD as the center, and gradually extended from the central area along the road to the marginal area.(2) By changing the traffic location and economic location, the railway obviously will pull up the land value of the four node cities, and the value-added effect was significant. In 2020, After the railway was opened to traffic,the expected land price of Vientiane will be like with the price of prefecture-level city in YunNan Province. The expected land price of Luang Prabang will be like with the price of county-level city in YunNan Province. The expected land price of Muang xay and VangVieng, will be like with the price of county town in YunNan Province.(3) In 2020, the price of Railway site set up regional land will increase significantly, and will become another center,where the land price only less than CBD. the land value-added potential of these regions will be the biggest. And these regions will be able to obtain a higher rate of return on investment. In addition, the setting of each node city railway station will increase the flow of production factors, which increasing the land price of both sides of the main road in cities. The land value-added potential of these areas will be relatively large. Because of it’s high degree of development, the CBD of city will has low mercantile rate of return. |
