Abstract

Increasing soil surface roughness can be effective in enhancing infiltration of rainfall and depression storage capacity of forest soil and reducing surface run-off. In this study, a forest slope with hemispherical depressions shows greater infiltration of water, whereas depression storage capacity is higher in soil with depressions perpendicular to a water flow pathway. Soil pitting or forming surface depressions can be used as a countermeasure after forest fires and a practical way to reduce drought stress of forest soil.

토양 표면에 요면(굴곡)을 형성하는 것은 토양의 거칠기를 증가시켜 강우의 침투와 토양의 저류능력을 향상시키고 지표수 및 토사의 유실량을 감소시키는 효과적 방법이 될 수 있다. 이 연구에서 토양 표면에 형성된 요면의 모양이 지표수의 흐름에 반구형일 때 수평 및 수직형일 때보다 침투량이 많았고, 토양의 저류능력은 수직형 요면에서 높았다. 흙 파기, 또는 토양 표면의 요면 형성은 산림 토양에서 산불 발생 후 대책으로, 또 건기 때 가뭄 스트레스를 해소하는 실용적인 방법으로 활용될 수 있다.
