| 摘 要： | 全球变化包含气候变化、经济发展、土地利用变化等自然、人为及共同作用下引发的转变,是当前景观结构与功能保障面临的主要挑战。景观生态适应性是指景观这一地表镶嵌体吸纳上述影响并维持主要功能的特性,涉及不同景观类型、组成单元及层级在不同时空尺度中的不同程度转变。本文从景观生态学视角切入,以景观系统作为缓解与适应全球变化冲击的主体,整合农业景观、城市景观等相关研究案例,凝练当前景观系统适应全球变化过程的特征为：①由部分因子的绝对主导转向复合因子共同作用;②景观类型内部趋同,景观多样性及独特性降低;③同类景观间功能等级分明、分工明确,跨区域时空联系增强;④不同景观类型间空间边界清晰,过渡带景观功能退化。就当前全球变化议题,建议后续研究应加强：不同景观类型或组成单元的适应能力对比及其不确定性分析;基于景观系统整体健康的适应途径尺度联系解析;多学科、多部门研究在全球变化情景下的有效整合;景观系统适应性或适应能力量化分析方法的深化。 |

| Abstract: | Global change is an integral phenomenon including the impact of climate change, social development, land-use change, as well as other natural and anthropogenic effects and their interactions, which has become the most important driving forces of change in landscape systems. The adaptation of landscape system mainly involves absorbing the consequences of global change and maintaining the principal functions of landscape. This adaptive capacity encompasses different landscape types and components of the system and varying degrees of change in different temporal and spatial scales. From the perspective of landscape ecology, this study takes landscape systems as the main objects for alleviating and adapting to the risks and transformations of global change. We summarize the current adaptive characteristics of the landscape system by integrating relevant landscape research such as agriculture landscape and urban landscape. In the process of adaptation, landscape system shows the following characteristics: (1) The interactions and joint impacts of natural and anthropogenic factors are pronounced (2) The internal geographic characteristics of landscape types are assimilated, and diversity and uniqueness of landscape systems are decreasing (3) Landscapes functions are much more hierarchical, demonstrating clear division of responsibilities and more strength of cross-regional linkages in different spatial-temporal scales (4) A clear spatial boundary exists between different functional landscape types, and the functional degradation of transitional or buffer zones has become more serious. Based on these characteristics, future work should focus on improving the following aspects to relieve the impacts of global change: (1) Adaptability and uncertainty analysis of different landscape types or units (2) Cross scale adaptation approach analysis based on holistic improvement of system health (3) Integration of multidisciplinary and multisector studies under the background of global change (4) Promotion of quantitative analysis method of adaptability of landscape system. |
