济南市三生空间时空格局变化特征分析

Analysis of the Spatial-Temporal Pattern Changes of Production-Living-Ecology Spaces in Jinan City

随着工业化、城镇化和农业现代化进程的持续推进,国土空间功能与格局发生剧烈演变,国土空间可持续开发与利用面临严峻的危机和挑战,分析三生空间的时空格局变化是构建国土空间开发保护新格局的前提。以济南市为例,基于ArcGIS平台将长时间序列的土地利用调查数据序列重分类为生产空间、生活空间与生态空间,采用GIS技术方法,探究了济南市2005~2020年三生空间的时空格局变化特征。结果表明:①在空间分布格局上,济南市三生空间变化不大,整体呈现三生空间协调发展的态势;②2005~2020年,济南市生产空间减少666.67 km^(2),生活空间和生态空间分别增加了577.24 km^(2)以及89.44 km^(2);③2005~2002年,济南市生产空间从呈现西北-东南分布,中心点在逐渐东移,生活空间呈现南-北分布趋势,中心点逐渐北移,生态空间逐渐由西北-东南方向分布向东-西方向分布转变,中心点逐渐西北移动。

With the continuous advancement of industrialization,urbanization and agricultural modernization,the functions and patterns of land space have undergone dramatic evolution,and the sustainable development and utilization of land space are facing severe crises and challenges.Analysing the changes of the spatial and temporal patterns of three living spaces is the premise of building a new pattern of land space development and protection.Taking Jinan City as an example,based on ArcGIS platform,this paper reclassifies the long-time series of land use survey data sequence into production space,living space and ecological space,and uses GIS technology to explore the spatial-temporal pattern change characteristics of Jinan's three living spaces from 2005 to 2020.The results show that:①in terms of spatial distribution patterns,Jinan's Sansheng space has little change,and the overall situation of coordinated development of Sansheng space is presented;②From 2005 to 2020,the production space in Jinan City decreased by 666.67 km^(2).Living space and ecological space increased by 577.24 km^(2) and 89.44 km^(2),respectively;③From 2005 to 202,the production space in Jinan City was distributed from northwest to southeast;the centre point was gradually moving east;the living space was distributed from south to north;the centre point was gradually moving north;the ecological space was gradually changing from northwest to southeast to east to west,and the centre point was gradually moving from west to north.
