본 연구는 기계학습을 기반으로 제작한 수량예측모델을 이용하여 PCR 4.5 시나리오에 따른 사일리지용 옥수수(WCC)의 피해량 산정 및 전자지도를 작성할 목적으로 수행하였다. WCC 데이터는 수입적응성 시험보고서(n=1,219), 국립축산과학원 시험연구보고서(n=1,294), 한국축산학회지(n=8), 한국초지조사료학회지(n=707) 및 학위논문(n=4)에서 총 3,232점을 수집하였으며, 기상데이터는 기상청의 기상자료개방포털에서 수집하였다. 본 연구에서 이상기상에 따른 WCC의 피해량은 RCP 4.5 시나리오에 따른 월평균기온 및 강수량을 시간단위로 환산하여 준용하여 산정하였다. 정상기상에서 DMY 예측값은 13,845~19,347 kg/ha 범위로 나타났다. 이상기상에 따른 피해량은 이상기온 2050 및 2100년 각각 -263~360 및-1,023~92 kg/ha, 이상강수량 2050 및 2100년 각각 -17~-2 및-12~2 kg/ha였다. 월평균기온이 증가함에 따라서 WCC의 DMY는 증가하는 경향으로 나타났다. RCP 4.5 시나리오를 통해 산정한 WCC의 피해량은 QGIS를 이용하여 전자지도로 제시하였다. 본 연구는 온실가스 저감이 진행된 시나리오를 이용했지만, 추가 연구는 온실가스 저감이 되지 않은 RCP 시나리오를 이용한 연구를 수행할 필요가 있다.

This study was conducted to estimate the damage of Whole Crop Corn (WCC; Zea Mays L.) according to abnormal climate using machine learning as the Representative Concentration Pathway (RCP) 4.5 and present the damage through mapping. The collected WCC data was 3,232. The climate data was collected from the Korea Meteorological Administration's meteorological data open portal. The machine learning model used DeepCrossing. The damage was calculated using climate data from the automated synoptic observing system (ASOS, 95 sites) by machine learning. The calculation of damage was the difference between the dry matter yield (DMY)normal and DMYabnormal. The normal climate was set as the 40-year of climate data according to the year of WCC data (1978-2017). The level of abnormal climate by temperature and precipitation was set as RCP 4.5 standard. The DMYnormal ranged from 13,845-19,347 kg/ha. The damage of WCC which was differed depending on the region and level of abnormal climate where abnormal temperature and precipitation occurred. The damage of abnormal temperature in 2050 and 2100 ranged from -263 to 360 and -1,023 to 92 kg/ha, respectively. The damage of abnormal precipitation in 2050 and 2100 was ranged from -17 to 2 and -12 to 2 kg/ha, respectively. The maximum damage was 360 kg/ha that the abnormal temperature in 2050. As the average monthly temperature increases, the DMY of WCC tends to increase. The damage calculated through the RCP 4.5 standard was presented as a mapping using QGIS. Although this study applied the scenario in which greenhouse gas reduction was carried out, additional research needs to be conducted applying an RCP scenario in which greenhouse gas reduction is not performed.
