동해안 고래불사구 염생식물 생육지의 토양환경 특성

Abstract

This study was to carry out the soil environment of halophyte community in Golaebul coastal sand-dunes of East Coast from April to October 2008. Vegetation of the coastal dune was classified as 7 communities : Carex kobomugi, Vitex rotundifolia, Elymus mollis, Ixeris repens, Lathyrus japonicus, Calystegia soldanella and Zoysia macrostachya community, and which were distributed zonation thoughout the coastal sand-dunes. Moisture content(1.5-4.0%) and organic matter content(0.2-0.35%) in the coastal dune were below which has typical characteristics of the coastal dune. There was little difference in salinity among the communities except high values oniy in Calystegia soldanella community. The soil particle size distribution in the coastal dune showed soil particle size of medium sand(250㎛ ~ 500㎛) which is high percent of the coastal dune. The results of this suggest those of the stucture of in Golaebul coastal sand-dunes of East coastal dune stysy affected by the halophyte community and the soil environment factors.
