지리산국립공원 동부지역 야영장 조성지와 인접 산림지역의 토양 특성 비교

초록

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(0～15㎝) and subsurface soil(15～30㎝) for the two areas(p>0.05). In case of soil bulk density, its values in campsites were significantly higher (1.29～1.44g/㎤) than in forest areas(0.95g/㎤), while soil hardness was significantly lower(p<0.05)in forest areas(1.44㎏/㎠) than in campsites(2.9～4.0㎏/㎠). Soil pore space was significantly lower in campsites(45.7～51.4%) 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 5.49 to pH 6.38. In addition, water infiltration was significantly lower in campsites(0.79～2.06cc/sec) than in forest areas(18.7cc/sec), while soil respiration rates were significantly higher in forest areas(0.58gCO2/㎡/h) than in campsites(0.13～0.34gCO2/㎡/h).
