摘要
随着城镇化的快速推进,生态环境问题日益突出,提高城市生态效率是缓解生态环境问题与推进生态文明建设的重要途径。基于此,以东北地区37个城市为研究对象,提出城镇化进程中生态效率响应系数概念,并据此测量城镇化进程中37个城市生态效率响应强度的空间差异。结果显示:2007—2018年,东北地区城镇化水平总体呈上升趋势,13个城市生态效率水平呈上升趋势,其余城市生态效率总体呈下降趋势,城镇化进程中生态效率响应强度总体呈下降趋势,空间差异明显,各城市之间响应强度差距逐渐缩小。依据生态效率应度强度变化特征,将37个城市划分为超前响应型、强响应型、较强响应型、弱响应型、滞后响应型。
With the rapid advancement of urbanization,ecological environment problems have become increasingly prominent.To alleviate the ecological environment problems,it is crucial to improve urban ecological efficiency which further contributes to promoting the construction of ecological civilization.Based on this,this paper takes 37 cities in Northeast China as the research object,proposes the concept of response coefficient of ecological efficiency in the process of urbanization,and measures the spatial difference of loudness intensity of eco-efficiency in 37 cities in the process of urbanization.The results show that the overall level of urbanization in Northeast China showed an upward trend from 2007 to 2018,while 13 cities showed an upward trend in ecological efficiency,and the rest showed an overall downward trend.In the process of urbanization,the response intensity of ecological efficiency showed an overall downward trend,and the spatial differences were obvious,while the response intensity gap among cities gradually narrowed.According to the variation characteristics of loudness intensity of ecological efficiency,37 cities were divided into advanced response type,strong response type,strong response type,weak response type and lagging response type.
