Abstract: River-crossing channel,as an important infrastructure to support city river-crossing development,can break through the barrier of natural waterway and accelerate the river-crossing flow of all kinds of production factors,and effectively promote the urban development and land value increment of riverfront sub-city.This paper puts forward the method of land price trend separation,and combined with other methods such as coefficient correction and factors superposition,it uses GIS to carry out the estimation of added value on residential land price in riverfront sub-city owing to the single channel as well as the multiple channels with Pukou District as an example.Research shows that residential land price gradients and contribution rates of single-channel decline gradually as the distance increase from the channel node,while the value-added effect of multi-channels presents a pattern of multi-center wave processing.By the predicted year(2020),the residential land price rise of commuter channels can reach about 52.54%around the node region of channels,while transiting channels only 31.52%.Based on the value-added effect of multi-channels,it can be estimated that the total increment of residential land price in "Pukou New Town" can go up to 40.48 billion yuan.This will raise large amounts of money for the urban infrastructure construction of Pukou District,and implement the river-crossing development strategy effectively.
