摘要
以2015年全国25个省会城市的建成区面积为研究对象,选择影响城市建成区面积的经济社会影响因子,将最小二乘法与Matlab软件相结合,研究及预测了城市建成区面积的影响因素,同时较好地解决了运用传统的纯数学方法的计算量大、计算过程麻烦的问题。研究结果表明:建成区面积主要受生产总值、第二产业、工业、第三产业的影响,即经济指标的影响程度较大。
With the built-up areas of the 25 provincial capital cities in 2015 as the research object,the authors of this paper determine the economic and social factors affecting the urban built-up areas,combine Partial Least Square and Matlab,study and predict the influencing factors of the urban built-up area.In this way the problem of overmuch calculation and a troublesome calculation process with a traditional mathematical method can be solved.The research results show that the built-up areas are mainly affected by the gross value,secondary industries,industries,and the tertiary industries,ie,the impact of the economic indicators is greater.
