Zoysia matrella, which is native to the Korean Peninsula, is a plant that grows in warm regions. Zoysia matrella has resistance to rust, high density of leaves and delicate texture, so it is used for soccer and golf courses, but it has limitations in that it cannot endure in low temperatures. In this study, the annual daily minimum temperature was used to identify the cultivation area of Zoysia matrella. The research data is the daily minimum temperature between 1992 and 2021 collected from synoptic meteorological observation equipment. In order to fit the generalized extreme value distribution, the daily minimum temperature was replaced with a negative transformation. The parameters were estimated by the L-moment estimation method because the number of samples was insufficient, and the Anderson-Darling test was used for goodness of fit test. Universal kriging is used in order to reflect the characteristic that the temperature decreases as the altitude. The low-altitude areas of the southern part of the Korean Peninsula and the west and east coasts are suitable for cultivation of Zoysia matrella.
