The coupling relationship between landscape patterns and ecological processes is one of the key issues in the research of landscape ecology. The pattern-process relationship is critical for researchers to understand the related scientific topics in landscape ecology. We systematically reviewed the current references of pattern-process coupling studies in landscape ecology. Then, we highlighted the scientific gaps in the aspects of methodology and relationships between landscape patterns and ecological processes. Based on the key issues of this topic, we present a research outlook on landscape ecology in terms of six fields: breakthrough of basic pattern-process theories, integration of modern technologies and methods, extension and strengthening of study objects, coupling of natural-humanistic-social perspectives, management and practice of pattern-process activities. A planning roadmap was discussed for the pattern-process coupling research of landscape ecology. For example, we should improve the accuracy of landscape pattern quantification and investigate the differences of landscape effects due to the research scales. Moreover, we should promote the timeliness of ecological process modeling. All these suggestions were potentially useful for a deep understanding of landscape ecology.
