Soil disturbance caused by timber harvesting is widely recognized as a potential threat to forest utilization. The degree and extent of soil disturbance is believed to vary with respect to harvesting methods and logging machines. This study has conducted to assess the degree of soil disturbance asso...

방사선을 이용하는 토양샘플링 방법은 무엇인가? | , 1999). 방사선을 이용하는 방법은 방사선의 수분밀도(nuclear moisturedensity) 를 이용하여 지표면을 굴삭하지 않고 현장에서 쉽고 빠르게 토양의 물리적 성질을 조사하는 방법이다 (Blake and Hartge, 1986). 이 방법은 조사장비의 무게가 약 20 kg로 무거워 휴대성이 떨어지고, 조사시에는 반드시 자격을 취득한 사람이 필요하기 때문에 산림지에 적용하기에는 많은 한계가 있다(Flint and Childs, 1984). | |
토양교란에 영향을 끼치는 요인은 무엇인가? | , 2004). 이 때의 토양교란은 임업 기계 및 타이어의 종류, 주행횟수, 작업시기, 지형, 토양 피복상태, 토성, 토양수분함량 등에 따라 다르게 발생된다(Froehlich et al., 1981; Laffan et al. | |
방사선을 이용하는 토양샘플링 방법의 한계는 무엇인가? | 방사선을 이용하는 방법은 방사선의 수분밀도(nuclear moisturedensity) 를 이용하여 지표면을 굴삭하지 않고 현장에서 쉽고 빠르게 토양의 물리적 성질을 조사하는 방법이다 (Blake and Hartge, 1986). 이 방법은 조사장비의 무게가 약 20 kg로 무거워 휴대성이 떨어지고, 조사시에는 반드시 자격을 취득한 사람이 필요하기 때문에 산림지에 적용하기에는 많은 한계가 있다(Flint and Childs, 1984). 토양시료캔을 이용하는 방법은 조사과정에서 토양용적밀도 및 공극률이 과다하게 추정되는 경향이 있지만, 현장에서 쉽고 간단하게 토양의 물리적 성질을 측정할 수 있기 때문에 많이 적용되고 있다(Page-Dumoroese et al. |
