【Abstract】 From the fact that investment will increase the land price a mathematical model of average land price along a constructed or expanded road line is established. Based on the method of 4-3-2-1, the mathematical model of the average land price on two sides of the road is given. As an application of this model, the land evaluation of Jiangbei District. Ningbo is given.更多还原
