On the basis of traditional aesthetics, contemporary western aesthetic circles add environmental aesthetics with ecological ethical thinking, trying to solve the increasingly serious ecological environment problems and subvert people’s inherent values through its theory and practice. Landscape aesthetics, as an important branch of environmental aesthetics, should seek effective intervention of new ideas with epochal criticism on the basis of in-depth exploration of its historical form. Based on the vertical time axis, this study combed the traditional aesthetic theory and its application in landscape practice, summed up the transformation of landscape aesthetics from subject-object dichotomy to experience-based empiricism, and introduced ecological ethics and scientific knowledge into contemporary landscape aesthetics to determine its value orientation of the times, in order to provide theoretical reference for solving ecological crisis and expanding the study of landscape aesthetics.
