ABSTRACT
Coastal sand dune area is an important ecosystem as an ecotone which is located between coastal area and terrestrial area. In order to understand the sand dune ecosystem in terms of its habitat characteristics, micrometeorological analysis was carried out in a coastal sand dune in Hakampo, Taeanhaean National Park, Korea. Micrometeorological measurements were made to monitor air and soil temperatures, relative humidity, soil water content, rainfall, solar radiation, wind speed, and wind direction. In contrary to a forest ecosystem, the coastal sand dune grassland ecosystem was relatively hotter and very humid with heavy rainfalls concentrated between June and July. The seasonal change of daily mean soil temperature was greater than that of air temperature by 2~3oC. Daily mean soil water content was less than 10% throughout the year. Also, the maximum wind speed of 156.7 m s-1 was recorded on 7 October 2011. The observed seasonal wind direction was different from those observed at Seosan by KMA (Korea Meteorological Administration). To better understand the habitat characteristics in a costal sand dune grassland ecosystem, long-term multi-year measurements are needed.

적요

해안사구는 해양생태계에서 내륙생태계로 이행하는 생태 이행대(ecotone)로서 중요한 생태계이다. 이러한 독특한 생태계의 서식지 특성 분석의 일환으로 우리나라에서 사구가 가장 넓게 분포하는 지역인 태안해안국립공원에서 미기상 요인(기온, 지온, 상대습도, 토양수분함량, 강우량 및 일사량, 풍향 및 풍속)의 통년 관측자료를 이용하여 계절변화를 분석하였다. 해안사구 초지생태계에서 미기상 요인의 계절변화는 산림생태계와 비교하여 상대적으로 고온 다습하며 6월과 7월에 집중 강우를 보였다. 토양온도는 기온보다 평균 2~3oC 높은 상태로 계절변화 하였으며 토양수분함량은 연중 10% 미만으로 매우 건조한 특성을 나타내었다. 또한 2011년 최고 풍속은 156.72m s−1(10월 7일)를 기록하였고 현지 측정한 풍향과 기상청 자료는 상이함을 알 수 있었다. 해안사구 초지생태계의 서식지 특성을 더 잘 이해하기 위해서는 이러한 미기상 요인의 통년 장기관측이 필요할 것이다.
