조간대 저토 환경과 갈대의 생장 특성 = Sediment Properties and Growth of Phragmites australisin Mud Tidal Flat

다국어 초록 (Multilingual Abstract)

This study examined the relationship between Phragmites australis` growth and sediment properties at mud tidal flat of Donggum-ri, Gilsang-myeon, Gangwha-gun, Incheon city. Field survey was carried out from May, 2010 to October, 2010. Water content, soil texture, electric conductivity and water table depth for sediment, density, height, dry weight and flowering for P. australiswere examined at several plots from the starting point (the coastal embankment) to the end point of the two populations. The result was as follows. Firstly, the water table increased along distance from the embankment at one line (N-line) but was similar at the other line (S-line) in a P. asustralispopulation. Water tables were higher out of than within a P. australispopulation at two populations. Secondary, in N-line, the height and dry weight of P. australis decreased along the distance from embankment but, in S-line, those were similar in its population. P. australis` growth was dependent on electric conductivity at lower layer (water table level) rather than upper one (the surface). Thirdly, density of P. australis changed during growing season and was similar in a population, except for the end point of patch. In summary, the growth and distribution of P. australiswere dependent on salt content of tidal flat`s sediment (water table level) and this was affected by fresh water of the inland.
