摘要
选取宿迁市1997～2007年耕地变更调查统计数据,分别采用趋势预测法、线性回归法和灰色数列模型对该市耕地总量变化态势进行建模,并利用模型进行未来耕地需求量预测,最后根据预测结果对3种预测方法进行分析讨论。
With the statistical data of Suqian arable land during1997 - 2007 being selected, the trend prediction method, the linear regression method and the grey sequence method is used to carried on respectively modeling to the change of total quantity of the arable land of the Suqian city, by which predicted value of the total quantity of the arable land of the city during 2008 - 2012 is obtained. The discussions on all the three kinds of prediction methods can be contributable to the land use plan of Suqian city to some extent.
