서울시 생태계 보전지역인 진관내동 습지, 방이동 습지와 밤섬에서 2004년 3월 토양을 채취한 후 5월부터 10월까지 유묘출현법(seedling emergence method)으로 토양 종자은행을 관찰하였다. 그 결과 진관내동에서는 총 42종, 5,190개체가 출현하였고,방이동에서는 총 39종, 2,265개체, 밤섬에서는 총 39종, 1,047개체가 발아하였으며 가장 개체수가 많았던 곳은 진관내동 버드나무군락이었다. 진관내동 습지와 밤섬에서 가장 많은 개체수를 보인 것은 밭뚝외풀이었고 방이동 습지에서는 부들속 식물들이었다. 진관내동과 방이동에서 실시한 군락별 토양 종자은행 조사 결과 갈대군락, 버드나무군락, 고마리군락, 달뿌리풀군락, 은사시나무군락 등에서 지상부 우점종과 지하부 우점종이서로 다른 반면 애기부들군락과 부들군락에서는 일치하였다.습윤조건에서 56종, 침수조건에서 25종이 출현하였고, 두 조건에서 다 출현한 종은 18종이었다. 개구리밥등의 부유식물과 물닭개비등의 일부 정수식물은 침수조건에서만 발아하였다. 부들속 식물, 돌피 골풀 등의 정수식물은 습윤과 침수 조건 모두에서발아하였다. 밤섬에서 채취한 수변으로부터의 거리별 토양 종자은행에서는 수위의 유동성이 큰 수변 3(식생대로부터 거리300~350m)에서 가장 많은 수의 종자가 관찰되었다.

Abstract
Soil seed banks at ecological preservation areas in Seoul, Jinkwannae-dong, Bangi-dong andBam-sum, were studied by seedling emergence method from May to October 2004. Total number of species and individuals in seed banks were 42 and 5,190 at Jinkwannae-dong, 39 and 2,290 at Bangi-dong, and 39 and 1,047 at Bamsum. Salix koreensis comunity at Jinkwannae-dong has the highest number of seedlings among all sites. The most abundant species were Lindernia procumbens in Jinkwannae-dong and Bam-sum and Typha re different from that of plant comunities such as Phragmites comunis community, Salix koreensis comunity, Persicaria thunbergii community, Phragmites japonica community, and Populus tomentiglandulosa community. However the dominant species of seed banks in Typha comunity was Typha spp. Total 63 species emerged in either the wet or submerged conditions. Fifty six species appeared in the wet condition and 25 in the submerged condition. Eighteen species appeared in both conditions. Numbers of species and individuals were much less in the submerged condition than in the wet condition but free-floating hydrophytes including Rorippa islandicaMonochoria vaginalis appeared only in the submerged condition. In the investigation of soil seed bank by distance from water edge (Bamsum), water side 3 (300~350m from water) edge, where water level is fluctuating frequently, has the highest number of seedlings.
