Abstract

All In this study, we focused on evaluating the quality of ecological environment m governance in eleven cities within Zhejiang Province. We employed a comprehensive set of key indicators, including the proportion of days with air quality meeting or exceeding Grade II standards, annual average concentrations of sulfur dioxide (SO_2), nitrogen dioxide (NO_2), particulate matter with a diameter of 10 micrometers or less (PM10), the 95th percentile daily concentration of carbon monoxide (CO), and the 90th percentile 8-hour maximum concentration of ozone (O_3). We utilized methods such as entropy values, information utility values, and weight allocation techniques to conduct a holistic assessment of urban ecological environment governance.Our findings revealed significant advantages in terms of Ritchie’s fitting values (RSR fitting values) for Zhoushan and Lishui cities, ranking them in the third tier. This underscores the commendable efforts of these two cities in improving air quality. Simultaneously, Huzhou city, while displaying relatively lower fitting values, demonstrates substantial potential in ecological environment governance. Additionally, key indicators such as the 90th percentile 8-hour maximum concentration of ozone (O_3) and annual average concentration of particulate matter (PM10) play pivotal roles in the overall evaluation.The comprehensive assessment framework presented in this study offers a thorough and accurate perspective on urban ecological environment governance. This approach can guide policy formulation and environmental management, albeit requiring further refinement and practical implementation. In summary, our research provides valuable insights for advancing ecological civilization construction through an in-depth analysis of urban ecological environment governance in Zhejiang Province.
