Abstract

Predicting possible distributed area of Schisandra chinensis which has long term cultivation period among non-timber forest products is needed to be studied to deal with climate change. Hence, distribution of Schisandra chinensis in the 2050s and 2070s was predicted under two scenario, RCP 4.5 and RCP 8.5, with ensemble of 5 climate models used in IPCC AR5. According to estimation using RCP 4.5, distribution of Schisandra chinensis in 2050s appeared to decrease 43% of current area and appeared to decrease 57% in 2070s respectively. Moreover, According to estimation using RCP 8.5, distribution of Schisandra chinensis in 2050s appeared to decrease 55% of current area and appeared to decrease 85% in 2070s. As a final outcome, Schisandra chinensis was estimated to extinct in the future except Gangwon-do and Gyeongsangbuk-do when analyzing change between current distributed area and future distributed area. As a result, those areas were classified as vulnerable areas to climate change. Therefore, Gangwon-do and Gyeongsangbuk-do were thought to be ideal for growing Schisandra chinensis. The result from this study can be used to provide basic information for selecting proper area of Schisandra chinensis considering climate change effect.

단기소득임산물 중 재배기간이 비교적 긴 오미자는 기후변화 영향에 대응하기 위해 재배적지의 변화 양상을 파악할 필요가 있다. 이에 RCP 4.5 및 RCP 8.5 두 가지 시나리오에 대해 IPCC 5차보고서에 사용된 기후모델 중 5가지를 앙상블하여 2050년대와 2070년대의 오미자 분포를 예측하였다. 분석결과 RCP 4.5를 기준으로 하였을 때 현재 재배적지의 43%정도가 감소할 것으로 예측되었으며 2070년대에는 57%정도 감소할 것으로 나타났다. RCP 8.5시나리오에서는 2050년대에 55%정도가 감소할 것으로 나타났으며, 2070년대에 현재의 86%까지 감소할 것으로 나타났다. 기후변화 취약지역 분석결과 강원도와 경상북도 일부를 제외한 지역들이 모두 기후변화 취약지역으로 분류되어 기후변화 영향 최소화를 위해서는 강원도와 경상북도 북부지역에서 재배하는 것이 효과적일 것으로 판단되었다.
