Based on the Web of Science (WoS) and the ranking table of the Chinese Academy of Sciences (2021 upgraded version), ten high-frequency and high-impact English journals related to landscape architecture were selected. The metrics such as journal overview, impact factor and ranking, article influence and eigenfactor, journal citation indicator, downloads and authors were counted and used for the vertical and horizontal analysis. The development law of 10 English journals based on key metrics from 2016 to 2020 was summarized, which indicated the characteristics of obvious interdisciplinary characteristics, dynamic improvement of the metric system, and high demand for international English journals by domestic researchers. Through the quantitative analysis of the highly cited literature after the inclusion of the WoS database and the past five years, it is concluded that the urban climate (thermal comfort, climate change, plants, etc.), comprehensive performance (ecosystem services, health, biodiversity, etc.), urbanization (China, urban growth, policies, etc.) are the persistent focus and research hotspot of 10 English journals related to landscape architecture. The research in the field of the ecological economy (economic growth, carbon emissions, energy consumption) has increased in recent years. This research provides an important reference for domestic academic journals in the field of landscape architecture to promote the development and intersection of disciplines and explore high-quality development paths.
