Construction Land Supply And Demand Analysis And Empirical Research

In land use planning implementation, to promote the rational utilization of land in have a role to play, but also met with many problems, one of which is to construction land supply planning index doesn't conform to social economy development, this is due to the actual demand of construction land without thorough research forecast method. A new round of land use planning, the new era background is urgently needed to construction land, in-depth study demand forecast, in order to realize the construction land market supply and demand balance, the general land use planning for the compilation provides scientific basis.This paper firstly construction land supply and demand of the theoretical basis and background are summarized, and then to construction land supply and demand, the two aspects, and then analyzes the factors that affect demand forecasting model choice land for construction purposes. From the land use planning, according to the reality of the principle of first to use the land for construction and related factors affecting the preliminary selection, then use the correlation analysis of key factors. According to the factors, using the screening of regression analysis building construction land demand forecasting the multivariate linear regression model, and to optimize the model with fixed, in order to make the model is more scientific, higher precision. Given the gray system theory GM (1,1) model of the sample quantity is not high, and can change desalt uncertainty affect the process of establishment of the model, construction land demand forecasting, and carries on the residual fixed, so as to improve the prediction precision. This paper also choose SPSS statistical relatively and DPS statistical software, this study applies statistical data analysis and modeling.This is the core of construction land demand forecasting model, and study in NuJiang State of Yunnan province as an example, NuJiang State combined with practical,1996 to 2005, ten years of social and economic statistical data and the data of the construction land, the detailed analysis and studies. Firstly with grey model GM (1,1), to construction land demand forecasting, Then using multiple-grey prediction model is established, the coupling of multiple linear regression model, and to optimize the model, using GM (1,1) model predictive factors related to multiple regression model and the GM (1,1) model, thus improving the advantages of the prediction accuracy. Finally, through the comparison with actual data analysis, the optimum model, coupled with grey forecasting model, NuJiang State 2010 and 2020 construction land demand forecasting, determine NuJiang State rotational acetabular osteoto my planning.Finally to construction land supply and summarize the study adequately, construction land demand forecast in land use planning, in order to better role in a new round of land use planning.
