摘要:
[目的] 研究经济发展与生态环境之间的关系,为长江经济带高质量发展和三峡库区经济与生态协调发展提供政策参考。[方法] 以三峡库区重庆段为研究区域,基于脱钩模型对2006-2018年经济与生态环境"脱钩状态"(分为绝对脱钩、相对脱钩、临界状态、耦合状态)进行判定。结合探索性空间数据分析(ESDA)法,运用ArcGIS,OpenGeoDa软件对脱钩状态相关数据进行空间差异及格局演化特征分析。[结果] 三峡库区重庆段整体的脱钩系数偏低,空间相关性较弱;在2006-2010年和2014-2018年脱钩系数主要表现出空间正相关,2010-2014年期间主要表现出空间负相关;从局部空间自相关(LISA)图分析得出,研究区各区县之间的脱钩状态显著性较弱;研究区在3个研究时间段的脱钩状态呈现出显著的倒"V"型发展趋势。[结论] 2006-2018年来,三峡库区经济发展与生态环境耦合特征波动较大,亟需进一步深入研究并制定相关整治措施。

Abstract:
[Objective] The relationship between economic development and the ecological environment was studied in order to provide a reference for high-quality development in the Yangtze River economic belt and coordinated development of the economy and ecology in the Three Gorges reservoir area.[Methods] Taking the Chongqing section of the Three Gorges reservoir area as a study area, the decoupling status of the economy (absolute decoupling, relative decoupling, critical, coupled) and the ecological environment from 2006 to 2018 was judged based on the decoupling model. After combining these data based on the exploratory spatial data analysis(ESDA) method, the spatial differences and pattern evolution characteristics of the decoupling data were analyzed using ArcGIS and OpenGeoDa.[Results] The overall decoupling coefficient of the Chongqing section of the Three Gorges reservoir area was low and the spatial correlation was weak. The decoupling coefficients showed mainly positive spatial correlation in 2006-2010 and 2014-2018 and showed negative spatial correlation from 2010-2014. Local indicators of spatial associaton(LISA) chart analysis showed that the significance was weaker, and the overall change showed significant inversion of the V-shaped development trend in the three time periods.[Conclusion] From 2006 to 2018, the coupling characteristics of economic development and the ecological environment in the Three Gorges reservoir area fluctuated greatly. Therefore, it is urgent to study this area further and formulate relevant regulation measures.
