- 摘要:
- 探究广西壮族自治区生态保护与高质量发展的时空耦合关系,为区域可持续发展提供新思路和依据。运用TOPSIS模型测算2010—2019年广西生态保护与高质量发展指数,并采用耦合协调度模型、空间自相关模型剖析两者的协调水平、时空演变趋势及集聚效应。结果显示:(1)广西生态保护水平呈波动增长态势,生态保护高水平城市主要分布在桂东北部,低水平集中于中部与南部沿海城市,桂西部城市主要为“中间区”,生态保护模式已由粗放式向全域型转变;(2)广西高质量发展水平经历了“加速增长—稳步优化—提质增效”的演变进程,指数由0.256升至0.622,在空间上大致呈“十”型带状发展格局;(3)广西生态保护与高质量发展协调水平持续提升,逐步转入初级与中级协调阶段,各市协调类型经历了“濒临失调—勉强协调—初级协调—中级协调”的梯度提升阶段,形成了“一核三副三带”高低发展态势;(4)广西市际间的协调度Moran's I指数均为负值且表现为下降趋势,呈负相关分布特征,市域差异持续增大,玉林、南宁、柳州、桂林市成为区域高值极化主区域。将“五位一体”发展理念贯穿经济发展,持续推进生态治理修复工作,是推动生态保护与高质量发展高水平协调并进的要点。
- Abstract:
- The spatiotemporal coupling relationship between ecological protection and high-quality development in Guangxi Zhuang Autonomous Region was examined in order to provide new ideas and basis for regional sustainable development, we used the TOPSIS model to calculate the 2010—2019 Guangxi ecological protection and high-quality development index, and used the coupling coordination degree model and the spatial autocorrelation model to analyze the level of coordination, temporal and spatial evolution and agglomeration effect of the two. The results show that:(1)the level of ecological protection in Guangxi showed a fluctuating growth trend; cities with high levels of ecological protection are mainly located in northeastern Guangxi, while cities with low levels of ecological protection concentrated in the central and southern coastal cities, ‘middle area' is mainly located in western Guangxi. Transition to a global type;(2)the level of high-quality development in Guangxi had undergone an evolutionary process of ‘accelerating growth, steady optimization, improving quality and efficiency', with the index rose from 0.256 to 0.622, showing a spatially similar ‘+' shaped belt development pattern;(3)Guangxi's ecological protection and high-quality development coordination level continued to improve, gradually transited to the primary and intermediate coordination stage, the coordination type of each city had experienced a gradient improvement stage of ‘endangered-barely, barely coordinated, coordinated-primary, intermediate coordination', forming a high and low development trend of ‘one core, three secondary and three belts';(4)the Moran's I index of inter-city coordination in Guangxi was negative and showed a downward trend, showing negative correlation distribution characteristics, difference between cities continued to increase, and Yulin, Nanning, Liuzhou, Guilin City had become a regional high-value polarization main areas. Applying the ‘Five-sphere integrated' development concept to economic development and continuing to promote ecological governance and restoration is the key to promote the high-level coordination of ecological protection and high-quality development.
