| 随着工业化和城镇化持续快速发展,多元化驱动力促使土地结构与功能发生极大转变。本文基于景观生态学原理,借助景观格局指数与ArcGIS分析方法,采用结构多样性、集中度分析可从类型与数量刻画土地利用结变化,弥补均匀时序间隔忽视阶段结构共性的不足,探讨广东省改革开放35年来土地利用数量结构、配置,时段转移特征,探究主要社会经济驱动力。结果表明：①近35年广东省土地利用组合以“林地+水田”为主,地类结构阶段变化具有明显节点(1990、1995、2000)②据节点对各阶段地类转移特征、空间动态度进行了分析,驱动因子显示常住人口数与地区生产总值(GDP)为核心驱动力。③本研究进行了城乡转型背景下土地动态监测、机制解析与效应评估以及合理管控等研究内容的框架讨论,旨在以地域空间转型的动态监测为载体,厘清城乡转型背景下人类活动与土地利用的耦合关系,通过科学管控土地资源利用以破解社会发展与土地利用之间的“困局”。 |

| With the rapid development of industrialization and urbanization, the diversified driving force has greatly changed the structure and function of the land. This paper uses the principle of landscape ecology, and uses the landscape pattern index and ArcGIS analysis method to explore the land use quantity structure, configuration, and time shift characteristics of Guangdong Province in the past 35 years, and explore the main socio-economic drivers. The results show that In the past 35 years, the combination of land use in Guangdong Province has been dominated by "forest land + paddy field", the stage changes of land use quantity structure in Guangdong Province have obvious nodes (1990,1995,2000). According to the node, the characteristics and spatial dynamics of land class transfer in different stages are analyzed.The driving factors of each stage show that the number of permanent residents and the gross domestic product (GDP) are the core driving forces. This study explores the framework discussion of land dynamics monitoring, mechanism analysis and effect evaluation, and rational control and control in the context of urban-rural transformation. It aims to use the dynamic monitoring of regional spatial transformation as a carrier to conduct an in-depth study of human activities and land use in the context of urban-rural transformation. The coupling relationship scientifically controls the use of land resources to break the "difficulties" between social development and land use. |
