지리산 국립공원 동부지 역에 위치한 중산리, 백무동, 대원사 산구야영장 등 4개의 야영장조성지와 인접한 산림지역의 토양 특성을 비교한 결과 토양용적밀도, 토양경도, 토양 pH, 투수율, 토양호흡율 등의 토양 특성은 산림지역과 야영장 조성지 사이에 차이가 있었다(p<0.05). 그러나 표토($0{\sim}15cm$)와 심토($15{\sim}30cm$) 사이에 깊이별 토양특성은 야영장 조성지와 산림지역 모두 차이가 없었다(p>0.05). 토양용적밀도의 경우 산림지역 $0.95g/cm^3$, 야영장 조성지 $1.29{\sim}1.44g/cm^3$로, 야영장 조성지가 산림지역에 비해 높았으며, 토양경도는 산림지역 $1.44kg/cm^2$, 야영장 조성지 $2.9{\sim}4.0kg/cm^2$로 유의적인 차이가 있었다(p<0.05). 토양공극율의 경우 산림지역은 64.3%로 야영장 조성지 $45.7{\sim}51.4%$에 비해 높았고, 토양 PH는 산림지역 pH 5.46, 야영장 조성지 $pH\;5.49{\sim}pH\;6.38$ 범위에 분포하였다. 투수율의 경우산림지역 18.7cc/초, 야영장 조성지 $0.79{\sim}2.06cc$/초, 토양호흡율은 산림지역 $0.58gCO_2/m^2/h$로, 야영장 조성지 $0.13{\sim}0.34gCO_2/m^2/h$에 비해 높게 나타났다.
This study was carried out to evaluate soil property between campsites located at Joongsanri, Daewonsa old, Daewonsa new, Baekmudong and their adjoining forest areas in the eastern area of Jirisan National Park. The survey results showed that there existed a significant difference(p<0.05) between the two areas in soil property, such as soil bulk density, soil hardness, soil pH, water infiltration and soil respiration rates. However, there was no difference in soil property by depth between surface soil($0{\sim}15cm$) and subsurface soil($15{\sim}30cm$) for the two areas(p>0.05). In case of soil bulk density, its values in campsites were significantly higher ($1.29{\sim}1.44g/cm^3$) than in forest areas($0.95g/cm^3$), while soil hardness was significantly lower(p<0.05) in forest areas($1.44kg/cm^2$) than in campsites($2.9{\sim}4.0kg/cm^2$). Soil pore space was significantly lower in campsites($45.7{\sim}51.4%$) than in forest areas(64.3%), and soil pH in forest areas indicated pH 5.46 and that of the campsites was distributed at the range from pH 6.49 to pH 6.38. In addition, water infiltration was significantly lower in campsites($0.79{\sim}2.06cc/sec$) than in forest areas(18.7cc/sec), while soil respiration rates were significantly higher in forest areas($0.58gCO_2/m^2/h$) than in campsites($0.13{\sim}0.34gCO_2/m^2/h$).
