摘要

摘要:
区域联防联控能够实现温室气体和大气污染物协同减排，粤港澳大湾区已开展多项环境合作项目，具有较好的气候变化和大气污染协同控制基础，对区域层面温室气体和大气污染物协同控制现状进行研究，具有重要意义。以粤港澳大湾区11个市（区）2005—2020年的历史数据为基础，在全局熵值法的基础上选取4个一级指标（子系统）、20个二级指标构建了温室气体和大气污染物协同控制现状评价指标体系，并采用耦合协调度模型测算各指标之间的耦合度。结果表明：粤港澳大湾区温室气体和大气污染物协同控制综合评价得分总体呈上升趋势，其中生态环境水平指标得分相对滞后，影响了协同控制水平的提升；11个市（区）的协同控制水平得分均有不同程度的提高，但是一级指标间的得分差异较大；4个子系统之间的耦合度为高度耦合，耦合协调度均为较低协调水平，各子系统正处于协调发展阶段，相互之间的作用力还很小，上升发展空间较大。粤港澳三地不同的环境管理体系和环境治理诉求是制约粤港澳大湾区温室气体与大气污染物协同控制发展的主要原因。

Abstract:
Regional joint prevention and control can realize the coordinated emission reduction of greenhouse gases and air pollutants. Guangdong-Hong Kong-Macao Greater Bay Area (GBA) has carried out a number of environmental cooperation projects, which has a good foundation for the co-control of climate change and air pollution. It is of great significance to study the current situation of the co-control of greenhouse gases and air pollutants at the regional level. Based on the historical data of 11 cities/regions in GBA from 2005 to 2020, a co-control evaluation index system of greenhouse gases and air pollutants was constructed by selecting 4 first-level indicators and 20 second-level indicators based on the global entropy method, and the coupling coordination degree model was used to measure the coupling degree of each indicator. The results showed that the comprehensive evaluation score of the co-control of greenhouse gases and air pollutants in GBA showed an upward trend, and the score of the eco-environmental level index lagged behind, which affected the improvement of the co-control level. The scores of co-control level of 11 cities/regions all had varying degrees of increase, but the score difference between the first-level indicators was larger. The coupling between the four subsystems was high coupling, and the coupling coordination degree was low coordination level. The subsystems were in the stage of coordinated development, and the interaction force between them was still small, so there was a large space for improvement. The different environmental management systems and environmental governance demands of the three areas were the main reasons that restricted the co-control development of greenhouse gases and air pollutants in GBA.
