摘要
以京津冀城市群为研究对象,通过整合夜间灯光数据构建表征城市化的综合灯光指数,整合日光遥感MODIS数据并构建表征生态环境质量的遥感生态指数,研究京津冀城市群2000—2020年间城市化强度与生态环境的时空格局演变,结合耦合协调度模型分析两者的协同发展关系,为京津冀城市群城市化与生态环境和谐共生提供理论支持和科学决策。研究结果显示:1)京津冀城市群各城市的城市化发展具有空间差异性,呈现中南高、西北低、层次分明的空间格局,2000—2010年为城市化缓慢发展阶段,2010—2020年为城市化迅速发展阶段;2)2000—2020年京津冀城市群遥感生态指数波动起伏较大,但在整体上遥感生态环境指数由2000年的0.48增长到2020年的0.58,生态环境质量变好,在生态等级变化上,主要形成差及较差向中等生态等级转变,中等向良好生态等级转变,良好向优生态等级转变的态势;3)2000—2020年间京津冀城市群耦合协调类型在转型发展的前提下,由濒临失调—城市化滞后朝着中度协调—生态环境滞后方向过渡发展,城市群在推进城市化的进程中需加强对生态环境的保护。
Taking the Beijing-Tianjin-Hebei urban agglomeration as the research object,this study constructed a comprehensive light index representing urbanization by integrating night light data,and a remote sensing ecological index representing ecological environment quality by integrating daylight remote sensing MODIS data.The spatial-temporal evolution of urbanization intensity and ecological environment in the Beijing-Tianjin-Hebei urban agglomeration from 2000 to 2020 was studied.Combined with the coupling coordination degree model,the synergistic development relationship between the two was analyzed to provide theoretical support and scientific decision-making for the harmonious coexistence of urbanization and ecological environment in the region.The results show that:1)Urbanization development exhibited spatial differences across cities,showing a distinct spatial pattern of high levels in the central south and low levels in the northwest.From 2000 to 2010,urbanization developed slowly,while 2010 to 2020 marked a period of rapid development.2)From 2000 to 2020,the remote sensing ecological index(RSEI)of the Beijing-Tianjin-Hebei urban agglomeration fluctuated greatly.However,on the whole,the RSEI increased from 0.48 in 2000 to 0.58 in 2020,indicating an improvement in the ecological environment quality.In terms of the change in ecological grade,there was a transformation mainly from the poor and relatively poor ecological grades to the medium ecological grade,from the medium ecological grade to the good ecological grade,and from the good ecological grade to the excellent ecological grade.3)Over the past two decades,the coupling coordination type of the Beijing-Tianjin-Hebei urban agglomeration has transitioned from near-maladjustment with urbanization lag to moderate coordination with ecological environment lag,under the precondition of transformation development.Strengthening ecological protection remains essential as urbanization continues to advance.
