【摘要】：城市化是我国提高经济实力、促进城乡发展、改善人民生活水平的必然选择。然而,随着经济改革和工业化进程的加快,我国的生态环境正面临着空前的压力,灰霾等空气污染事件引发公众关注。城市化与空气质量间相互作用并彼此影响,二者的关系复杂且长期处于动态变化之中。探索城市化与空气质量的相互作用关系、识别城市化过程中影响空气质量的风险因子,有助于人们正确认识当前城市发展与空气污染的时空特征,辅助政府提出保护大气环境、改善空气质量的对策。据此,本文构建城市化与空气质量耦合关系模型,分析浙江省城市化与空气质量耦合协调关系;运用地理探测器探寻空气质量、PM2.5浓度的风险因子,分析风险因子间的异同,提出针对性对策建议。具体研究内容有以下三方面:(1)从人口、经济、土地和社会角度选取和建立城市化指标体系,以年均空气质量指数(AQI)表征浙江省空气质量水平,计算、分析浙江省2013年-2015年各市城市化水平、空气质量水平。(2)在城市化、空气质量评价结果基础上,构建浙江省城市化与空气质量耦合关系模型,定量分析浙江省2013年-2015年各市城市化与空气质量间的耦合协调关系。(3)根据耦合协调度计算结果,将浙江省分为协调区(杭州、嘉兴、宁波、舟山)、准协调区(湖州、绍兴、金华、温州、台州)、欠协调区(衢州、丽水)。采用地理探测器对2015年浙江省及其三分区进行空气质量、PM2.5浓度的风险因子探测,探究不同城市化发展阶段的风险因子及其决定力的差异,识别风险因子与风险事件的相关趋势,评估双因子交互后的共同作用会否增加或减弱对风险事件的解释力,并提出针对性的对策建议。
[Abstract]:Urbanization is the inevitable choice to improve the economic strength, promote the development of urban and rural areas and improve the people's living standard. However, with the acceleration of economic reform and industrialization, the ecological environment of our country is facing unprecedented pressure. Air pollution events such as haze have aroused public concern. Urbanization and air quality interact and affect each other. The relationship between them is complex and dynamic for a long time. To explore the interaction between urbanization and air quality and to identify the risk factors affecting air quality in the process of urbanization. It is helpful for people to correctly understand the space-time characteristics of urban development and air pollution and assist the government to put forward countermeasures to protect the atmospheric environment and improve air quality. In this paper, the coupling relationship between urbanization and air quality is established, and the coupling and coordination between urbanization and air quality in Zhejiang Province is analyzed. Using geographical detectors to explore the risk factors of air quality PM2.5 concentration, analyze the similarities and differences between risk factors, and put forward targeted countermeasures and suggestions. The specific contents of the study are as follows: 1) from the population. The index system of urbanization was selected and established from the angle of economy, land and society, and the average annual air quality index (AQI) was used to characterize the level of air quality in Zhejiang Province. This paper analyzes the urbanization level and air quality level of each city in Zhejiang Province from 2013 to 2015) based on the evaluation results of urbanization and air quality. The coupling model of urbanization and air quality in Zhejiang Province was constructed. Quantitative analysis of the coupling coordination relationship between urbanization and air quality in various cities of Zhejiang Province from 2013 to 2015) according to the calculation results of coupling coordination degree, Zhejiang Province is divided into coordination areas (Hangzhou, Jiaxing). Ningbo, Zhoushan, quasi-coordinated area (Huzhou, Shaoxing, Jinhua, Wenzhou, Taizhou, uncoordinated area (Quzhou, Lishui). Air quality of Zhejiang Province and its three subzones in 2015 using Geographic detector. " PM2.5 concentration of risk factors detection, explore the different urbanization stages of risk factors and their determinants, identify risk factors and risk events related trends. To evaluate whether the interaction of two factors will increase or weaken the explanatory power of risk events, and put forward some countermeasures and suggestions.
