This paper was aimed to review the research trends on the subject of ′landscape′ that were published in the Journal of the Korean Institute of Landscape Architecture (KILA) over the 30 years from 1973 to 2003. The total number of articles with the "landscape" subject is 132(12.1%) out of 1,089(the total number of articles). The ratio of the ′landscape′ articles to the total number of the two decades between 1980 and 1999 increased at 8.7% and 1.1% respectively, and decreased at 5.3% since 2000. It was found that each decade showed its own trend of research subject. The first trend during the 1980′s focused on the methodology of analyzing the characteristics of landscape. The second trend during 1990′s converged to the positivistic research method, which relies on computer technology. A new and very important trend began during the same decade. It was "visual landscape planning", which attracted much attention since the operation of local autonomy in Korea. This trend focuses on ′visual landscape planning′, and it is expected to grow drastically in the near future. Therefore, it is recommended that we promote the more elaborate methodology of ′visual landscape planning′, which also includes the ecological and cultural aspects of the environment.
