Abstract

This study addressed soil disturbances following harvesting as well as soil physical and hydrological properties within three first-order headwater catchments characterized by ephemeral-intermittent streams. Four treatments representing a range of potential Best Management Practices(BMPs) for ephemeral-intermittent streams were used; BMP1, BMP2, clearcut and reference. This study includes 1 year of pre- and post-harvest observations. Results showed that post-harvest disturbances were closely related with harvesting intensity and generally tended to reflect changes in soil physical and hydrological properties following harvest with the except of bulk density and porosity. Forest clearcutting decreased macroporosity and saturated hydraulic conductivity, and increased soil resistence as a result of severe soil disturbances thereby increasing soil erosion. These impacts were reduced by implementing two BMP treatments during harvesting activities. The finding support the use of either BMP treatments for ephemeral-intermittent streams, however, the additional measure of leaving logging debris in BMP2 did not cover enough soil surface to reduce erosion.

본 연구는 산림유역의 일시하천과 간헐천이 상존하는 수변지역을 대상으로 산림벌채로 인한 토양의 교란 정도를 평가하고, 물리적 수문학적 특성 변화 양상을 파악하였다. 총 12개 소유역에서 4개의 처리구(BMP1, BMP2, 개벌구, 대조구)를 적용하였으며, 각 처리구별 벌채 전 후 1년 동안의 모니터링 결과를 비교 분석하였다. 그 결과, 벌채 후 산정된 교란등급은 벌채강도와 상관이 있는 것으로 나타났으며, 조사된 토양의 물리적 수문학적 특성 변화와 일치하는 경향을 보였다. 그러나, 용적밀도 및 공극률의 변화와는 일치하지 않았다. 전면개벌은 강도 높은 지표교란을 야기 시켰으며, 이로 인해 조공극률 및 투수계수는 감소, 토양강도는 증가하였고, 이는 토양의 침식의 간접적인 원인으로 작용하였다. 개벌구에서 강도 높은 지표 교란으로 야기된 토양의 물리적 수문학적 특성 변화는 BMP1과 BMP2에서 완화되는 것으로 나타났다. 그러나, 벌채 후 BMP2에 남겨진 벌채잔재물은 지표의 피복기능으로서의 침식을 완화하는 효과가 없는 것으로 나타났다.
