Hanon made in the largest maar crater in Korea, is the only paddy field ecosystem in Jeju Island that has been conducting rice farming, for the past 500 years. Flora surveys were conducted eight times, 2015-2018, to understand floristic characteristics and a restoration plan of the study area. As a ...

하논 화산은 어디에 위치하는가? | 하논 화산은 서귀포시 호근동과 서홍동 경계에 위치하며 동서방향으로 약 1.8 km, 남북방향으로 약 1. | |
우리나라 내륙지역에서 벼농사는 언제 시작된 것으로 추정되는가? | 우리나라 내륙지역에서 벼농사는 기원전 2000년경에 시작된 것으로 추정되며 (Cho 2008), 제주도에서는 1454년에 편찬된 「세종실록지리지」에 논에 대한 기록이 있는 것으로 보아 그 이전부터 벼농사를 지어왔던 것으로 추정된다 (Jeong 2014a). 제주도의 논 벼 재배면적은 1982년에 가장 넓은 면적인 1,112 ha였으며, 이후 급격히 감소하면서 현재는 8 ha로 집계되고 있다 (국가통계포털, http://kosis. | |
제주도의 논 벼 재배면적이 급격하게 감소한 원인은 무엇인가? | 1). 제주도에서 논 벼 면적의 급격한 감소 원인은 교통 발달에 따라 육지에서 제주도로 쌀이 충분히 공급되면서 쌀값이 폭락한 것이 주요 원인이다 (Jeong 2014a). 현재 제주도 논에서 벼농사가 이루어지고 있는 8 ha는 하논에서 현재 벼를 재배하고 있는 면적과 동일하며, 휴경 면적을 포함하면 하논의 경지면적은 약 23 ha가 된다. |
