Evolution And Trends In Landscape Visual Quality Assessment: A Scientometric Analysis Based On Citespace

Abstract

The visual landscape, shaped by both environmental representation and individual preferences, is a key aspect of the broader landscape. Assessing its characteristics and quality has become essential for landscape management and policy-making. This study analysed 329 publications on landscape visual quality assessment from the Web of Science (WOS) database (January 1989–February 2025) using CiteSpace 6.4 R1 for scientometric analysis. The findings reveal three research phases: cognition, intervention, and exploration of intrinsic mechanisms, marking a shift from aesthetics-focused studies to interdisciplinary approaches. Since 2013, publication volume has surged due to advances in assessment techniques, stabilising after 2021. The expert paradigm and psychophysical paradigm have significantly contributed to the field, yet concerns persist regarding the sustainability of assessment methods given the dynamic nature of environments and audiences. Additionally, the mechanisms underlying visual interactions between individuals and landscapes remain underexplored. By reviewing over three decades of research, this study highlights key trends and research gaps, offering a valuable reference for scholars seeking an overview of the field.
