【摘要】 环鄱阳湖城市群是中国中部地区重要的生态功能区和经济发展区域，其生态环境质量关系到区域生态系统的稳定性和可持续性。为客观评估该区域生态环境质量的时空变化及其影响因素，实现区域经济与生态平衡。通过选取2003—2022年5期Landsat遥感影像，运用主成分分析构建遥感生态指数，并结合Sen+Mann-Kendall检验、空间自相关和地理探测器等方法研究该区域生态环境质量的时空变化及驱动因子。结果表明：2003—2022年环鄱阳湖城市群生态环境质量呈现不显著改善趋势；其空间分布具有正相关性，西北部和东北部地区为高-高聚类，中部地区为低-低聚类；土地利用是影响环鄱阳湖城市群生态环境质量变化的关键因子，其空间分布与研究区生态环境质量等级为差的区域高度相关。此外，夜间灯光因子对生态环境质量的解释力表现为逐渐上升的趋势，表明生态环境质量变化与城镇化发展密不可分；交互探测结果均表现为增强，其中土地利用与年平均气温的交互效果增强显著。可见，研究成果对于指导环鄱阳湖城市群在城市化进程中科学合理地协调经济发展与生态保护的关系、实现可持续发展具有重要意义。更多还原

【Abstract】 The urban agglomeration around Poyang Lake is an important ecological function area and economic development area in central China, and its eco-environment quality is related to the stability and sustainability of the regional ecosystem. To objectively evaluate the spatio-temporal changes and influencing factors of the eco-environment quality in the region, and achieve regional economic and ecological balance. By selecting 5 Landsat remote sensing images from 2003 to 2022, principal component analysis was used to construct a remote sensing ecological index, and combined with Sen+Mann-Kendall test, spatial autocorrelation, and geodetector methods to study the spatio-temporal changes and driving factors of eco-environment quality in the region. The results show that there is no significant improvement trend in the eco-environment quality of the urban agglomeration around Poyang Lake from 2003 to 2022. The spatial distribution is positively correlated, with high-high clusters in the northwest and northeast regions, and low-low clusters in the central region. The land use is a key factor affecting the changes in eco-environment quality of the urban agglomeration around Poyang Lake, and its spatial distribution is highly correlated with areas with poor eco-environment quality levels in the study area. In addition, the explanatory power of nighttime light factor on eco-environment quality shows a gradual upward trend, indicating that the change of ecological environment quality is inseparable from the development of urbanization. The interaction detection results show enhancement, and the interaction effect between land use type and annual average temperature is significantly enhanced. It can be seen that the research results have important practical guiding significance for guiding the urban agglomeration around Poyang Lake to scientifically and rationally coordinate the relationship between economic development and ecological protection in the process of urbanization and achieve sustainable development.更多还原
