본 연구에서는 둔촌동 습지에서 미지형이 식물 군락 구성에 미치는 영향을 연구하기 위하여 2007~2008년에 걸쳐 지형에 따른 수위 변화와 식물 군락의 변화를 조사하였다. 조사 지역을 지대가 낮은 지형부터 높은 지형까지 4개 구역으로 구분하여 조사하였으며, 각각의 구역은 조사 지역 면적 대비 약 11%, 10%, 18%, 24%의 면적을 가지고 있었다. 조사 기간 동안 수환경의 pH는 6.10(±0.13), 전기전도도는 51.5(±6.0)㎲/cm이었으며, PO4-P, NO3-N, NH4-N은 각각 0.04(±0.02)mg/L, 0.14(±0.07)mg/L 그리고 0.01mg/L 이하로 유지되었다. 2008년 3~4월 누적 강수량이 2007년 대비 약 56%로 적었던 것이 지대가 낮은 지형에서 수위 환경 차이를 유발하여 식물 군락 형성에 매우 큰 영향을 미쳤으며, 지형의 높이에 따라 해당 구역을 우점하는 식물 길드가 다르게 나타났다. 이러한 결과는 종자로부터 생활사가 시작되는 1년생 식물 종들이 조사 지역을 전체적으로 우점하였기 때문이며, 다양한 길드의 식물들이 혼재하기 위해서는 높이 구배가 있는 미지형이 조성되어야 한다는 것을 의미한다.

The purpose of this study is to investigate the effect of micro-topography to vegetation pattern in Dunchon-dong wetland. To characterize the effect of micro-topography, changes in water level and vegetation pattern were monitored from 2007 to 2008. Depending on the relative elevation, the study site was divided into 4 sectors. The relative areas of sectors in ascending order were 11%, 10%, 18% and 24%, respectively. During investigation period, average water pH was 6.10 (±0.13), electron conductivity was 51.5 (±6.0)㎲/cm, PO4-P, NO3-N and NH4-N concentration were 0.04 (±0.02)mg/L, 0.14 (±0.07)mg/L, and lower than 0.01mg/L, respectively. Water level was very changeable in low-water season because the area of lowest sector was small. This characteristic increased the effect of difference of accumulated precipitation from March to April in 2007 and 2008 to plant community composition in lower sectors. Different plant guilds dominated respective sectors and annual plants were major dominant species in the study site. This study suggested that the elevation gradients are necessary to create the habitats for various plant guilds in wetland.
