식재 침엽수 숲길과 숲 가장자리 분포 식생 및 매토종자 비교 = Comparisons between a forest road with a Coniferous Plantation and Distributed Vegetation on the edge of a forest, and Reclaimed Soil Seed Bank

다국어 초록 (Multilingual Abstract)

The purpose of this study is to compare the differences in aboveground flora and underground flora between
a forest road and a forest edge and to clarify each characteristic through ecological approach to a forest road.
The study site was the forest planted with Pinus koraiensis and Abies holophylla,and located at an altitude of
45m(36°36′23″N 127°21′45″E). The width of the forest road is 3.2m.This research set the forest edge within
the areas 5m away from the forest road and also conducted a survey on vegetation 5 times from september 2006
to August 2007. In addition,it installed thirty six quadrats to make an analysis of reclaimed soil seed bank. Soil
amounting to 600㎤ was collected from each quadrat using soil samplers(100㎤),which was preserved in low
temperature refrigeration for a month. Soil was thinly strewed evenly on trays and watered every four or five
days; then, this research did experiment for six months until no more germination took place. Through this
process, this research identified species and counted the number of germinating individuals by using emerging
seedlings. The research result showed that on the whole, the similarity index between aboveground flora and
underground flora was low. The correlation coefficient between the aboveground flora vegetations both on the
forest road and on its edge was found to be 0.36, showing a correlation with each other(p<0.05). On the other
hand, the correlation coefficient between underground flora vegetations through the analysis of reclaimed soil
seed bank was 0.20, showing no correlation with each other(p>0.05). As the survey result of naturalized plants,
there existed 7 species of naturalized plants on the forest road in case woody plants were included,showing
11.11% naturalization rate and 2.61% urbanization index(UI). On the other hand in case woody plants were not
included among the naturalized plants, the naturalization rate on the forest road was 12.50% while the
naturalization rate on the edge of the forest was 9.09%.

본 연구는 숲길에 대한 생태학적 접근을 통하여 숲길과 숲 가장자리의 상부와 지하부식생을 비교하고 그 특성을 밝히는 것을 목적으로 하고 있다. 연구 장소는 잣나무와 전나무를 식재한 숲으로, 해발 고도는 45m이다(36°36′23″N 127°21′45″E). 숲길의 폭은 3.2m이며, 숲 가장자리는 숲 길가로부터 5m로 정하였다. 2006년 9월부터 2007년 8월까지 총 5번의 식생조사가 이루어졌다. 매토종자 분석을 위해 숲길과 숲 가장자리에서 각각 18곳의 방형구를 정하였다. 각각의 방형구마다 토양 샘플러로 600㎤토양을 채취하였고 저온처리를 위하여 한 달간 냉장 보관하였다. 포트에 토양을 골고루 얇게 펼친 후 4∼5일마다 급수하였으며, 더 이상 발아가 일어나지 않는 상태가 될 때까지 실험을 6개월 동안 실시하였다. 출현한 유식물의 이용하여 종과 발아개체수를 확인하였다. 연구 결과, 전체적으로 지상부식생과 지하부식생 사이의 유사도지수는 낮았다. 숲길과 숲 가장자리의 지상부식생간의 상관계수는 0.36으로 상관관계가 있었다(p<0.05). 매토종자 분석을 통한 지하부식생간의 상관계수는 0.20로, 서로 상관관계가 없었다(p>0.05). 귀화식물 조사결과, 목본을 포함하였을 경우 숲길 귀화식물은 7종, 귀화율은 12.50%이었으며, 도시화지율은 2.61%이었다. 숲 가장자리 귀화식물은 6종, 귀화율은 11.11%이었으며, 도시화율은 2.24%이었다. 귀화식물 중 목본을 포함하지 않았을 경우 숲길의 귀화율은 12.50%이나 숲 가장자리의 귀화율은 9.09%이었다.
