Abstract : There are a lot of effort for understanding geomorphic
processes and providing scientific valuation schemes of mountain
wetlands. Geochemical properties of wetland sediments may be
considered as signifi- cant indicators for environmental condition
of mountain wetlands. However we have not fully understood these
according to geomorphic setting. We intended to define geochemical
differences between head hollow type wetland and valley type
wetland based on geomorphic setting. Our study site, Cheonchuksan
(Mt.) Wetland, is located in Wangpicheon basin ecology-landscape
conservation area, eastern Korea and has four sub wetlands. We
divided four sub wetlands to head hollow type and valley type by
its geomorphic setting. There were significant differences in
particle sorting, organic matter, pH, EC, Ca2+, Mg2+, and Na+
between two wetland types. Sorting in particle size and pH of
sediments from valley type were higher than those from

head hollow type. On the other hand, organic matter, EC, Ca2+,
Mg2+, and Na+ from head hollow type were higher than those from
valley type. We also compared to geochemical properties between
wetland sediments and its adjacent soils. In valley type, there
were a little geochemical difference, except EC and Na+, between
sediment and soil. However, there were significantly differences
between sediment and soil in head hollow type. Organic matter, EC,
Ca2+, Mg2+, and Na+ of head hollow type wetland sediments were
higher than those of adjacent slope soils. These results show that
valley type wetland sediments are linked with its adja- cent slope
soils, but head hollow type wetland sediments are transformed from
its adjacent soils. This study suggest that geochemical properties
of wetland sediments should be significant indicators for
geomorphic condition of mountain wetlands. Furthermore, it gives
useful idea for environmental management scheme based on
geodiversity of wetlands.
