초록

제주도 지역을 대상으로 기후요인과 토양분포의 관계를 알아보기 위하여 기온, 강우량, 증발산량 등 기후요인을 이용하여 분석하였다. 온도를 기준으로 하여 중심지역의 Mesic상 지역과 주변부의 Thermic상 지역으로 구분하고, 월별 수분수지빈도를 기준으로 4개로 구분하여, 온도, 수분수지로 전체를 온대수분과 다지역(집단1), 난대수분과다지역(집단2), 난대수분균형지역(집단3), 난대수분부족지역(집단4), 난대수분매우부족지역(집단5)의 5개의 집단으로 구분할 수 있었다. 집단1에서 집단5로 갈수록 토양분류측면에서는 andisols, inceptisols, alfisols, ultisols의 분포 비중이, 토색측면에서는 흑색토양, 농암갈색토양, 암갈색토양의 분포비중이 높아지는 경향이었다.

We analyzed relationship soil distribution and climatic factors using temperature, precipitation and evapotranspiration maps in Jeju island. The whole area was divided into 5 groups - mesic high moisture region(group1), thermic high moisture region(group2), thermic balanced moisture region(group3), thermic short moisture region(group4), thermic very short moisture region(group5), by soil temperature and monthly moisture balances. By the sequence from group1 to group5, the occupation ratio of soils was increased in order of andisols, inceptisols, alfisols, ultisols in soil orders, and of black soils, very dark brown soils, dark brown soils in soil colors.
