摘要
"三生功能"视角下的国土空间动态变化特征分析有助于掌握国土空间格局与发展趋势,促进面向生态文明建设的城市群国土空间协调均衡利用。文章从数量变化、格局演变和重心转移等方面分析了山江海交错带广西北部湾城市群1995—2019年的国土三生空间(生产—生活—生态空间)变化特征,结果表明:(1)研究区三生空间呈"一核两横两纵"分布格局,生活、生产空间沿江沿海分布,并在山间丘陵和平原扩展,山地和河流是主要的生态空间。研究区的空间构成以绿地生态空间和农业生产空间为主,可见广西北部湾城市群具有提供生态、农业产品和服务的巨大潜力。(2)研究区三生空间冲突表现在城市化工业化进程中,城镇生活空间、农村生活空间和工矿生产空间增加,农业生产空间、绿地生态空间减少。(3)研究区的重心转移幅度由大到小依次是生活空间、生产空间和生态空间,可见1995—2019年研究区的生活空间建设较快,生态空间相对稳定,6个地级市之间的生活、生产重心呈现吸引靠拢的趋势,说明广西北部湾城市群联合发展与国土空间布局具有相关性。
From the perspectives of production-living-ecological functions,analyzing land dynamic change characteristics is helpful to understand the land spatial pattern and development trend,and promote the coordinated and balanced use of urban agglomeration land space. This paper analyzes the land change characteristics of Beibu Gulf urban agglomeration in Guangxi from the aspects of quantity change,pattern evolution and gravity center deviation during 1995 and 2019,the results show that: 1) It shows the spatial distribution characteristics of "one core,two horizontals and two verticals" in the study area. The living and production spaces distribute along the rivers and coast,and expand in the plains and mountains,mountains and rivers are the main ecological space. The study area is mainly composed of green ecological space and agricultural production space. It can be seen that Beibu Gulf urban agglomeration has great potential to provide ecological, agricultural products and services. 2) In the process of urbanization and industrialization, urban living space,rural living space and industrial production space show the increasing trend,while agricultural production space and green ecological space show the decreasing trend. 3) From 1995 to 2019, the range of the gravity center movement of living space in the study area is relatively obvious,but the ecological space is relatively stable. The living and production gravity centers of the six cities are moving closer to each others,which indicates that the joint development of Beibu Gulf urban agglomeration is related to the land spatial layout.
