摘要
以福州市2001-2013年建成区用地面积及社会经济发展各类数据为基础,利用岭回归分析对建成区用地规模的预测方程加以参数校正,重新选择变量,并再次建立新的岭回归模型。利用新建立的模型计算出2014-2017年建成区用地规模的预测值,加以验证。研究表明,模型的精度具有一定可靠性,可为福州市建成区用地规划管理提供相关建议。
Based on the data of land area and social and economic development of built-up areas in Fuzhou from 2001 to 2013,ridge regression analysis was used to correct the prediction equation of the scale of land use in built-up areas,reselect variables,and establish a new ridge regression model.The newly established model was used to calculate the predicted value of the land use scale of the built-up area from 2014 to 2017 and verify it.The research shows that the accuracy of the model has certain reliability,which can provide relevant suggestions for the planning and management of land use in built-up areas of Fuzhou.
