| 为揭示土地利用多功能的时空变化特征与耦合关系，促进广西边境地区形成高质量发展、高水平保护的国土空间新格局。本文选取广西边境地区23个县（市、区）作为研究对象，基于空间自相关和耦合协调模型，探讨研究区土地利用在时间序列和地域分布上的演变特征及功能间耦合协调关系。研究表明，2005—2022年，广西边境地区的生产功能均值从0.42下降至0.41，呈“N”字型；生活功能均值呈倒“V”型结构；生态功能均值由0.57上升至0.67，整体处于持续上升趋势。空间上，生产功能整体上表现为“核心高，边缘低”；生态功能反之；生活功能呈现离散分布状态。耦合协调均值由0.49增长至0.52，空间上表现为“北低，中、南高”。研究结果可为广西边境地区国土空间结构优化、资源配置、可持续发展提供新的研究思路，保障国土政治安全。 |

| Abstract: |
| To reveal the spatiotemporal characteristics and coupling relationships of multifunctional land use, and to promote the formation of a new spatial pattern of high-quality development and high-level protection in Guangxi"s border regions. This study examines 23 counties (cities and districts) in Guangxi"s border regions. Based on spatial autocorrelation and coupling coordination models, it investigates the temporal and spatial evolution of land use patterns within the study area, as well as the functional coupling and coordination relationships among land use types. Research indicates that from 2005 to 2022, the average production function in Guangxi"s border regions decreased from 0.42 to 0.41, exhibiting an “N”-shaped pattern; the average living function followed an inverted “V”-shaped structure; while the average ecological function rose from 0.57 to 0.67, maintaining an overall upward trend. Spatially, production functions generally exhibit a “high core, low periphery” pattern; ecological functions show the opposite; while living functions display a dispersed distribution. The coupling coordination mean increased from 0.49 to 0.52, exhibiting a spatial pattern characterized by “lower values in the north and higher values in the central and southern regions.” The research findings can provide new insights for optimizing the territorial spatial structure, allocating resources, and promoting sustainable development in Guangxi"s border regions, thereby safeguarding national territorial security. |
