随着现代化进程的推进与发展,城市群区域内的“三生”空间格局发生了变化。本报告以长江中游城市群为研究对象,通过动态度、标准差椭圆、景观格局分析、LEI指数等方法,对2000~2020年“三生”空间格局的演变情况进行宏观尺度和微观尺度的定量化研究。研究表明:一是20年来长江中游城市群生活空间保持稳定,生产空间逐步扩张,生态空间呈波动化下降。二是“三生”空间中农业生产空间、林地生态空间、水域生态空间面积转化最大。三是20年来三类空间的标准差椭圆长轴均为西北—东南走向,生产、生态空间与生活空间扩张方向相反;三类空间紧密程度变化存在差异;不同都市圈的生产生活空间演变趋势不同。
<<With the advancement and development of modernization,the spatial pattern of “living-production-ecological spaces” in the urban agglomerations has changed. This paper takes the middle reaches of Yangtze River urban agglomeration as the research object and conducts a quantitative study on the evolution of the spatial pattern of “living-production-ecological spaces” at macroscopic and microscopic scales from 2000 to 2020 by means of dynamic degree,standard deviation ellipse,landscape pattern analysis and LEI index. The main conclusions are as follows:①the living space of the middle reaches of Yangtze River urban agglomeration has remained stable over the past 20 years,while the production space has gradually expanded and the ecological space has fluctuated and decreased. ②The area transformation of agricultural production space,woodland ecological space and water ecological space is the largest among the living-production-ecological spaces. ③The long axis of the standard deviation ellipse of all three types of space in 20 years is northwest-southeast direction,and the production and ecological space are opposite to the expansion direction of living space;there are differences in the changes of the closeness of the three types of space;the evolution trends of production and living space in different metropolitan areas are different.
