Abstract:

As economy goes on, the construction land demands become bigger and bigger. The prediction of construction demands during land utilization planning, however, still need to be improved. This paper, based on a case study on Dongfang city, Hainan province, establishes regress model and grey model of economic development to predict the construction land demands in 2010 and 2020, indicating that the regress model has a better application, but the grey model produces a bigger variation as years goes by, which can be applied for reference only by some correction.
