The principles of landscape ecology based on the pattern-process relationship is the key to translate ecology research into "spatial language" of landscape ecological planning.By analyzing the connotations and denotations of spatial pattern and ecological process,it is thought that flow and movement of the "fast" process is more easily interfered and controlled by human activities,and then analyzed the coupling relationship of landscape patterns and ecological processes.By revealing the external behavior and internal mechanism of the coupling system from landscape function and landscape connectedness,the method of landscape spatial pattern optimization is putting forward,which mainly includes five steps:to evaluate the ecological functions;to analyze the coupling relationship of the system;to analyze the key process;to analyze the landscape connectedness of spatial pattern;and to optimize the spatial pattern.%景观生态学中的空间格局与生态过程关系原理,是生态学研究转化为景观生态规划设计所必需的“空间语言”之关键所在.研究分析了空间格局与生态过程的内涵与外延,认为“快”过程所对应的流动和迁移过程更容易受到人类活动的干扰与控制,并针对“陕”过程剖析了景观中格局与过程的动态耦合关系,继而从景观功能与景观连通性两方面,进一步揭示了格局-过程耦合系统的外在表现与内在机制,最终提出景观空间格局优化五步骤方法:景观功能评价、系统耦合关系分析、关键过程分析、景观连通性分析、空间格局优化.
