为评估和反映我国生态文明发展水平，结合联合国2030年可持续发展议程和国家生态文明建设目标，构建了以环境质量改善为核心的生态文明发展指标体系。基于市域评估单元，采用双目标渐进赋分，评估了京津冀、长三角和珠三角三个城市群的生态文明发展水平。结果表明，珠三角城市群生态文明发展水平最高，均值为69.95；其次是长三角城市群，均值为67.61，最后是京津冀城市群，均值为59.04。三个城市群生态文明发展水平的短板都体现在绿色环境领域。城市生态文明发展水平评估，揭示其生态文明建设的短板，为城市提升生态文明发展水平指明了方向。

In order to evaluate China's level of ecological civilization, a set of indicators was established according to the United Nations' 2030 Agenda for Sustainable Development and the goal of ecological civilization construction in China. Using the double-benchmark progressive method and taking a city as an evaluated unit, this study examines the level of ecological civilization of three typical urban agglomerations: Beijing-Tianjin-Hebei (Jingjinji), the Yangtze River Delta, and the Pearl River Delta. The results indicate that the ecological civilization level of the Pearl River Delta ranks highest (69.95) and the ecological civilization level of Jingjinji ranks lowest (59.04). Green environmental field is the shortcoming of the three urban agglomerations' EC level. The urban EC level evaluation data shows the shortcomings of the EC, and designate the direction for the EC development level.
