濕地의 地理的 分布와 環境要因 : 鼎足山 무제치늪을 中心으로 = Geographical distribution and environment of the Korean wetlands : with a special reference to Mujechi moor on Mt. Cheongjok, Ulsan city, Korea

다국어 초록 (Multilingual Abstract)

The definition, classification and geographical distribution of the Korean wetlands, along with major wetlands inventory were analysed based on available informations and own field survey. The similarity and difference between ten typical moors of Korea were also examined. The relationships between a topography, hydrology and water chemistry of the Mujechi moors I and Ⅱ during the last thirty two years were analysed using a tree ring analysis of pine trees, an aerial photograph interpretation and a measurement of firebreak line.
The obtained results are as follow :
1. Wetlands in Korean context can be defined as " Wetlands are transitional zone between terrestrial and aquatic ecosystems. It has not only characteristics of two ecosystems but also obtain certain unique characteristics of its own.
2. Major Korean wetlands are numbered seventy five, including nineteen estuarine wetlands, twenty-two lagoons, tidal flats on the western and southern, five lowland marshes, five riverine wetlands, and twenty upland moors. The Korean wetlands types were classified into six types according to the dominant vegetation type, hydrology environment and water chemistry, forming of peat and soil type.
3. The number of Korean wetlands plants are 68 family 395 species 2 varieties for the Korean wetlands, 40 family 105 species I variety for the moor, and 25 family 41 species for the Mujechi moor.
4. The comparison to water pH, dominant vegetation types, plant species and source of moisture between the Yong moor on Mt. Daeam and the Mujechi moor on Mt. cheongjok reveals that the Yong moor can be categorized as a bog, but Mujechi moor as a fen.
5. According to the climatic data(1946 - 1999) of Ulsan meteorological station, the precipitation shows very little variation, on the other hand the temperature increased. This may have some influences on the landscape change at the Mujechi moor.
6. The analysis of water chemistry at the Mujechi moor I and Ⅱ shows that average pH, DO and water temperature marked the lowest level at sites I and 4, but the highest level of average pH and DO at sites 3 and 6, Average pH, DO and water temperature at the inner parts of moor, which are sites 1, 2 and 4 shows a similar pattern. While, those of sites 3 and 6 at the fringe between wetlands and neighbouring slope show similar trend with site 7, which is formed by ground water. It may indicates that the Mujechi moor I and Ⅱ are principally maintained by a ground water than a rainfall during a dry season.
7. The analysis of aerial photographs(taken in 1978, 1988, 1998) indicates that the area of Mujechi moor I and Ⅱ are gradually decreased. The decreased rate of moor area was relatively high,ｉ.ｅ., -23.9%(1978 - 1988) and -12.6%(1988 - 1998) at the Mujechi moor Ⅱ.
8. The construction of a firebreak line and waterway along the moor I and Ⅱ since the December, 1995, appears to diverted watershed flow and prevent runoff into the moors. The analysis of GIS suggests that the decrease of watershed area were about 11,413.8㎡(12.1% of whole watershed area) at the moor I and 15,969.5㎡(40.4% of whole watershed area) at the moor Ⅱ.
9. The negative impact of firebreak line on the inflow of water into a moor and destruction of vegetation along the firebreak line are noticeable from the field survey.
