基于回归分析的城镇化发展对生态环境影响的研究——以Z市为例
Study on the Impact of Urbanization on Ecological Environment Based on Regression Analysis—Taking Z City as an Example

城镇化发展是衡量一个地区综合实力的重要因素，同时生态环境与人们的生产生活有着密不可分的关系。为研究城镇化发展对生态环境的影响，本文选取Z市相关数据，构建城镇化、生态环境指标体系，以城镇化发展相关指标为自变量，通过熵权法将生态环境有关的多个指标综合为因变量，运用R软件分析所获得的样本数据，通过逐步回归法建立多元回归方程。分析结果表明：人均生产总值等因素对生态环境正向影响显著，民用汽车拥有量对生态环境负向显著影响。基于上述分析结果，本文从人口、经济、社会等三方面对城镇化发展提出合理化意见，进而促进生态环境与城镇化和谐发展。
The development of urbanization is an important factor to measure the comprehensive strength of a region. At the same time, the ecological environment is inextricably linked with people’s pro-duction and life. In order to study the impact of urbanization development on the ecological envi-ronment, this paper selects the relevant data of Z city, constructs the urbanization and ecological environment index system, takes the relevant indicators of urbanization development as the in-dependent variables, and integrates multiple indicators related to the ecological environment through the entropy method. For the dependent variable, R software was used to analyze the sam-ple data obtained, and the multiple regression equation was established by stepwise regression method. The analysis results show that factors such as per capita GDP have a positive impact on the ecological environment, and the amount of civilian vehicles has a negative impact on the ecological environment. Based on the above analysis results, this paper proposes rationalization opinions on urbanization development from the three aspects of population, economy and society, and promotes the harmonious development of ecological environment and urbanization.
