본 연구의 목적은 동해안 석호 습지인 선유담에서 조름나물이 서식하는 부유성 매트를 중심으로 조름나물 서식지의 생태적 특성을 밝히고, 서식지를 보전하기 위한 방안을 제안하고자 한다. 식생학적 특성을 확인하기 위하여 부유성 매트의 조름나물 서식지를 중심으로 방형구를 이용한 식생조사를 수행하였다. 부유성 매트의 두께 및 수위,깊이별 유기물 함량을 조사하였다. 표층수의 pH, DO, EC, TDS를 측정하고, 인산, 질산, 암모늄, Ca, K, Na, Mg 의 양을 분석하였다. 선유담에는 총 78분류군의 식물이 서식하고 있으며, 부유성 매트의 조름나물 서식지에서 조름나물의 평균 피도는 62.6%, 평균 shoot 밀도는 71.2개/㎡로서 중요한 수반종은 갈대였다. 부유성 매트의 평균깊이는 조름나물 순군락에서 26.5㎝, 갈대-조름나물 군락에서 68.9㎝였으며, 매트 아래 수위는 각각 106.5㎝와17.7㎝였다. 매트의 유기물 함량은 아래로 내려갈수록 감소하여 5㎝ 깊이에서는 73.7%, 이후 40㎝ 깊이까지는43.5~54.6%, 40~60㎝ 깊이에서는 19.3~21.3%의 범위를 보였다. 표층수의 pH, DO, EC, TDS는 각각 5.06,46.1%, 59.4 ㎲/㎝, 29.3 ㎎/L였다. 물에서 인산, 질산, 암모늄의 농도는 각각 47.2, 9321, 15.9 ㎍/L였으며, Ca,K, Na, Mg의 농도는 11.1, 1.5, 15.1, 11.3 ㎎/L으로 확인되었다. 습지형 석호인 선유담의 조름나물 서식지는Hewett의 분류에서 저지대 군락의 일종에 해당한다. 선유담 습지의 조름나물 서식지를 보전하기 위하여 개방수면의 확보, 관찰로 설치, 오염물 유입을 막기 위한 주변 농지로부터의 유입수 차단이 필요하다.
Abstract
The purpose of this study is to investigate the properties of Menyanthes trifoliata habitat in coastal lagoons. To characterize plant composition in the habitats in the lagoon, the plot sampling method was applied. The depths of water and floating mat were measured. Surface water quality factors including pH, electrical conductivity (EC), dissolved oxygen (DO), and total dissolved solids (TDS) were measured in the sites. Phosphate, nitrate, ammonium, and major cations were measured in laboratory. The wetland has 78 taxa of wetland plants. The average coverage and density of M. trifoliata was 62.6% and 71.2/㎡, respectively and Phragmites australis is important associate in Sunyoodam lagoon. The average depths of floating mats were 26.5㎝ in M. trifoliata and 68.9㎝ in the P. australis-M. trifoliata communities, and the water depth below the mat was 106.5㎝ and 17.7㎝, respectively. The values of pH, DO, EC and TDS in the water were 5.06, 46.1%, 59.4 ㎲/㎝,and 29.3 ㎎/L, respectively. The concentrations of phosphate, nitrate, and ammonium showed 47.2, 9321, and 15.9 ㎍/L,respectively. The concentrations of Ca, K, Na, and Mg had 11.1, 1.5, 15.1, and 11.3 ㎎/L, respectively. The habitats of M. trifoliata in the lagoon corresponds to a kind of lowland communities in Hewett’s classification. To conserve the habitats of M. trifoliata in Sunyoodam lagoon, the supply of open water area, the construction of observation deck, and the block of inflow from the surrounding paddy fields are needed in the future.
