土地利用总体规划中的耕地需求量预测摘要土地利用总体规划中的需求量进行科学准确的预测,是制定国家、省市县级土地利用规划的基础要求。国家在新一轮的土地利用总体规划,主要强调了耕地的保护与可持续发展的问题,如何确定耕地的重要指标,需要对耕地的需求量做出有一个准确的预测。文章结合各地区土地利用总体规划的实例,论述了土地利用总体规划中土地需求量预测的基本原则、方法,以及基于不同方法下的耕地需求与测量来逐一进行阐述。本文从影响耕地需求量因素着手研究,构建多元回归的预测模型,对城市未来几年的耕地需求量进行了一定的预测和分析验证。39151
文章根据重庆市1997年-2007年的耕地变更调查的统计数据,利用SPSS软件,采用逐步回归分析的方法,对该地区的耕地总量进行了模拟预测。在采用趋势分析法下,得出的公式为:
采用该方程预测2010年的耕地需求量为2167854.52hm2;2020年的耕地需求量1839065.04 hm2。
在逐步回归分析下的预测结果如下,线性回归方程为:
代入现有数据,可以得出方程的结果也就是2008年耕地需求量预测出的耕地面积为1792076.84万公顷。

Abstract The country can predict our country farmland demanding in land use of overall planning scientifically and accurate ,is the basis of planning of national provincial and municipal level formulation,land use requirements. In this paper, it combined with the overall planning of land use in different areas of examples, it discusses the basic principle, method of land demand prediction of the overall planning of land use quantity, problems and conflict between land supply and demand coordinationto analyzed.Combined with the regional land-use planning instance, it discusses the basic principles of land use planning in forecasting demand for land, methods, and based on the needs and arable land under different methods to measure each elaborate. This article proceed from the impact of demand for arable land Factors, select the main factor to build Chongqing demand forecasting model predicted regression of arable land, to Chongqing next few years the demand for arable land for a certain predictions and analysis verification.
Article according to Chongqing in 1997 - Change of Cultivated Land Survey statistics in 2007, the use of SPSS software, using stepwise regression analysis, the total arable land in the region were simulated to predict. In the case of trend analysis, the resulting formula is: Using this equation forecast 2010 demand farmland 2167854.52hm2; 2020 years, the demand for arable land 1839065.04 hm2.
Predictions in regression analysis below, the linear regression equation:
Into the existing data can be drawn from the results of equations is the demand for arable land in 2008 predicted 17,920,768,400 hectares of arable land.
