초록

본 연구에서는 2007년 7월부터 2010년 10월까지 4년 동안 강원도 삼척시에서 산불유형과 산불의 피해로부터 회복정도에 따른 낙엽생산량과 낙엽에 의해 임상으로 이입되는 영양염류 함량을 비교하였다. 산불대조구, 수관화 발생 조사구 (C-1, C-3), 지표화 발생 조사구(G-2)에서 4년간 평균 낙엽생산량은 각각 $7.74{\pm}2.56$, $1.17{\pm}0.67$, $2.97{\pm}0.44$, $2.92{\pm}0.42ton{\cdot}ha^{-1}{\cdot}yr^{-1}$로 나타났다. 낙엽 생산을 통해 임상으로 이입되는 4년간 평균 총질소, 총인, 칼륨, 칼슘과 마그네슘의 양은 산불대조구에서 각각 $22.20{\pm}12.43$, $1.16{\pm}0.46$, $2.68{\pm}1.44$, $16.22{\pm}4.69$, $1.36{\pm}0.32kg{\cdot}ha^{-1}{\cdot}yr^{-1}$로 가장 높은 값을 보였으며, 수관화 발생 조사구(C-1)에서는 각각 $3.73{\pm}2.31$, $0.10{\pm}0.09$, $0.27{\pm}0.20$, $2.75{\pm}2.58$, $0.24{\pm}0.27kg{\cdot}ha^{-1}{\cdot}yr^{-1}$로 가장 낮은 결과를 보였다. 총질소, 총인, 칼륨, 칼슘 및 마그네슘의 5개의 영양염류를 합산하여 보면 낙엽에 의해 임상으로 이입되는 영양염류의 함량은 산불대조구 > 수관화 발생 조사구(C-3), 지표화 발생 조사구 (G-2) > 수관화 발생 조사구(C-1) 순으로 나타났다.

This study has compared the different types of forest fire sites and the unburned site at Samcheuk-si Gangwon-do by assessing the amount of litter production, nutrient concentration returned to forest floor from July 2007 through October 2010. The research showed that the average amounts of litterfall produced in the unburned site, the crown fire site(C-1), the crown fire site(C-3) and the ground fire site(G-2) were $7.74{\pm}2.56$, $1.17{\pm}0.67$, $2.97{\pm}0.44$ and $2.92{\pm}0.42ton{\cdot}ha^{-1}{\cdot}yr^{-1}$, respectively. In the unburned site, the average amounts of total nitogen(T-N), total phosphorus(T-P), potassium(K), calcium(Ca) and magnesium(Mg) returned to the forest floor were $22.20{\pm}12.43$, $1.16{\pm}0.46$, $2.68{\pm}1.44$, $16.22{\pm}4.69$ and $1.36{\pm}0.32 kg{\cdot}ha^{-1}{\cdot}yr^{-1}$, respectively whereas those in the crown fire site(C-1) were $3.73{\pm}2.31$, $0.10{\pm}0.09$, $0.27{\pm}0.20$, $2.75{\pm}2.58$ and $0.24{\pm}0.27 kg{\cdot}ha^{-1}{\cdot}yr^{-1}$, respectively. This study showed that the nutrient content returned to forest floor was higher in the following order: unburned site(Un) > crown fire site(C-3) > ground fire site(G-2) > crown fire site(C-1).
