This study aimed to examine the effect of users" natural experience characteristics (NEC) on subway station interior landscape preference characteristic (SSILPC) for user-centered indoor landscaping planning of subway station space. To this end, the NEC and SSILPC elements were derived. In addition, a survey was conducted targeting 124 adult men and women in their 20s to 50s residing in Busan. The survey period was for about a week from November 11 to November 18, 2022, and an online survey was conducted. For the analysis of this survey, frequency analysis, descriptive statistics analysis, Kruskal-Wallis test, χ²-test, and logistic regression etc. were conducted using the statistical analysis program SPSS Statistics 27.The results of the survey are as follows: First, the NEC of the users were divided into three categories: the degree of nature awareness, the degree of nature experience, and the opportunity to experience nature. And the SSILPC were classified into six categories: necessity of interior landscaping, plant species, plant classification, plant introduction form, planting technique, landscaping constituent method. Second, it was found that among the nature experience characteristics, the degree of nature awareness and the opportunity to experience nature had an effect on the SSILPC. This study is meaningful in suggesting a more user-centered direction for interior landscape planning of subway station space by examining how the user"s NEC affect the SSILPC.
