Abstract

High turbidity submersion due to torrential downpour is one of the factors that influences the plant growth. This study is focused on analyzing the plant's growth rate for Salix species such as gracilisyla, koreensis, glandulosa when these trees are waterlogged. The length of shoots for this control group in the natural state is 33.4% (gracilisyla), 24.3% (koreensis), 23.9% (glandulosa), however, they stopped growing in submersion. Compared to the leaf number of Salix species of this control group in the natural state, 144.5% (gracilisyla), 77.3% (koreensis), 40.3% (glandulosa) in the natural state 30 days, in 30 days submersion, the number of leaves is zero except koreensis. In the results of this experiment, Salix species stopped growing quickly when submersed. This study concludes that it is necessary to plant eco-friendly plants around the slope of the reservoir and dam where flooding takes place frequently.

집중호우에 의한 고탁도 침수는 식물 성장에 영향을 줄 수 있는 요소 중 하나이다. 따라서 본 연구에서는 버드나무속 식물인 갯버들, 버드나무, 왕버들을 이용하여 고탁도 침수 발생 시 식물 키 및 엽수를 파악하여 성장정도를 정량적으로 분석하였다. 식물 키에 대한 분석 결과 비침수 상태인 대조군에서는 30일 후 갯버들, 버드나무, 왕버들이 각각 33.4%, 24.3%, 23.9% 증가하였지만 고탁도의 침수가 시작되면 대부분 성장이 멈추었다. 엽수의 경우 대조군에서는 30일 후 갯버들, 버드나무, 왕버들이 각각 144.5%, 77.3%, 40.3% 증가하였지만 고탁도 침수가 30일 지속되면 버드나무를 제외한 식물의 엽수는 0개로 관찰되었다. 식물 성장에 대한 실험 결과 전반적으로 버드나무속 식물은 고탁도 침수가 지속되면 빠른 시간 내 성장이 멈추는 것으로 나타났다. 이 결과는 향후 침수가 빈번히 발생하는 임하호 및 상류하천 사면의 친환경적인 수목조성을 위한 기초자료가 될 것으로 판단한다.
