摘要
根据2018年全国31个省(自治区、直辖市)的人均寿命、人均GDP、海拔高度、森林覆盖率等数据,以人均寿命为因变量、其他为自变量,进行多元非线性回归分析。结果表明:人均寿命与人均GDP呈极显著的正相关、与海拔高度成极显著的负相关、与森林覆盖率成极显著的正相关。3个自变量因子与人均寿命的关联都极显著,而创造长寿生存环境的最容易措施是绿化。
According to the data of the life span per capita, GDP per capita, altitude and forest coverage of 31 provinces(autonomous regions and municipalities) in 2018, taking the life span per capita as dependent variable and taking others as independent variables, multiple nonlinear regression analysis was carried out. The results showed that the life span per capita had a significant positive correlation with GDP per capita, it had a significant negative correlation with altitude and it had a significant positive correlation with forest coverage. The correlations between the three independent variables and the life span per capita were all very significant. Greening was the easiest way to create longevity living environment.
