摘　　要：探讨城市群生态安全时空格局变化及其驱动力分析,可为当地可持续发展提供新视角,同时为区域生态文明建设提供科学依据。以环鄱阳湖城市群为研究对象,基于PSR模型构建生态安全评价指标体系,运用熵值法、灰色关联度法对研究区2010、2013、2016、2019年生态安全格局时空分布格局及驱动力进行分析。结果表明:(1)研究期间环鄱阳湖城市群生态安全格局总体相对稳定,2013年生态安全指数最高,2016年生态安全指数最低;(2)空间上,以九江、宜春为主的增长极在该城市群的区域生态安全格局变化较为显著,其他城市相对稳定;(3)城镇污水处理率、第三产业从业人员比重、工业废弃物综合利用率、生活无害化处理率是环鄱阳湖城市群生态安全的主要驱动力。基于以上研究,提出了坚持生态保护优先、因地制宜规划生态建设,调整种植和产业结构、提高公众生态保护意识等相关对策与建议,确保形成健康稳固的生态安全总体格局。Exploring the spatiotemporal pattern changes and driving forces of ecological security in urban agglomerations can provide a new perspective for local sustainable development and scientific basis for regional ecological civilization construction.This paper took the urban agglomeration around Poyang Lake as the research area,and used the Entropy Method and Grey Correlation Method to analyze the spatial and temporal distribution pattern and driving force of ecological security pattern in the research area in 2010,2013,2016 and 2019.The results showed that:(1)The ecological security pattern of the urban agglomeration around Poyang Lake was relatively stable from 2010 to 2019.The ecological security index was the highest in 2013 and the lowest in 2016.(2)Spatially,the growth poles dominated by Jiujiang and Yichun had obvious changes in the regional ecological security pattern of the urban agglomeration,and other cities were relatively stable.(3)The urban sewage treatment rate,the proportion of employees in the tertiary industry,the comprehensive utilization rate of industrial waste and the harmless treatment rate of life were the main driving force of ecological security in the urban agglomeration around Poyang Lake.Based on the above research,this paper puts forward some countermeasures and suggestions,such as adhering to the priority of ecological protection,planning ecological construction according to local conditions,adjusting planting and industrial structure and improving public awareness of ecological protection,ensuring the formation of a healthy and stable overall pattern of ecological security.
