백운산 지역에서 벌채지내 운재로의 회복에 관한 연구

Abstract

To investigate the restoration procedure on soil physical properties and vegetation at the surface of strip road affected by timber harvesting operation. This study was carried out at strip roads constructed between 1989 and 1994 in Mt. Baekun, Kwangyang, Chollanam-Do. Soil hardness of the surface layer was improved with change of time after strip road construction, but that of 7.6∼15 cm depth from the surface was not improved. According to linear regression analysis, it was estimated 16.6 years in 0∼7.5 cm and 16.9 years in 7.6∼15 cm soil depth to be restored to natural forest lands. The amount of surface soil erosion was 0.045m3/km/yr on strip roads constructed in 1989 and 1990, and road constructed in 1994 showed the highest value (4.5m3/km/yr). Vegetation coverage rates of road surface were 96.7% in strip roads constructed in 1990. Those of cutslope and fillslope were highest in roads constructed in 1990. The results indicated that strip roads were restored with change of time after road construction.
