基于Pearson相关系数及线性回归的新型城镇化与耕地面积变化研究——以宿迁市为例

Research on New Urbanization and Cultivated Land Change Based on Pearson Correlation Coefficient and Linear Regression——A Case of Suqian City

根据新型城镇化的内涵,利用复合指标法从人口城镇化、经济发展、社会公共环境三个层面构建宿迁市新型城镇化综合评价指标体系。在此基础上,利用Pearson相关性分析和回归分析的方法对宿迁市新型城镇化水平与耕地面积之间的关系进行分析。结果显示,2002-2012年耕地面积变化与新型城镇化发展成负相关,到2012-2016年趋势变化转为正相关,可以得出耕地面积变化与城镇化发展不是完全对立的,并由此提出相关建议。

According to the connotation of the new type of urbanization, the composite index method is used to construct a new comprehensive evaluation index system for urbanization in Suqian from the three levels of population urbanization, economic development and social public environment. On this basis, the use of Pearson correlation analysis and regression analysis method to analyze the relationship between the new urbanization level and cultivated area in Suqian. The results show that although the change in cultivated land area is negatively related to the development of new urbanization in 2002-2012, and the trend change is positively correlated in 2012-2016.lt can be concluded that the change of cultivated land area is not completely opposite to the development of urbanization, and thus put forward relevant recommendations.
