신갈나무 삼림토양과 떡갈나무 삼림토양에서 pH는 6.0∼6.6의 범위를 보였다. 총유기물량과 수용성 당류는 신갈나무삼림의 표층 토양에서 떡갈나무삼림토양에 비해 각각 1.4배, 1.3배 높게 나타났다. 섬유소 분해효소는 수직적 분포에서 신갈나무삼림토양의 표층은 하층에 비해 4.71배 높았고 떡갈나무삼림토양에서는 표층이 2.01배 높았다. 두 식생토양간 섬유소분해효소 활성도는 표층에서 신갈나무삼림토양이 떡갈나무삼림토양에 비해 1.69배 높았다. 섬유소 분해효소와 환경요인과의 상관관계 분석결과, 총유기물량과는 상관관계가 별로 나타나지 않으나(R^2=0.265) 수용성당류와 상관관계가 밀접하게 나타났다(R^2=0.623). 딘백질 분해효소는 표층에서는 신갈나무삼림토양이 1.46배 높았으나 하층에서는 떡갈나무삼림토양이 10배 늘은 상반된 경향을 보여주었다. phosphatase 활성도는 ALPase, NEPase, ACPase의 활성도가 신갈나무삼림토양의 표층에서 떡갈나무삼림토양의 표층 토양에 비해 각각 1.91, 1.52. 1.47배로 두 식생간 삼림토양간의 활성도 차이가 크게 나타났다 토양함수량과 phosphatase와의 상관관계분석 결과는 3가지 유형의 phosphatase 모두 높은 상관성을 가지며 특히 ACPase가 밀접한 관련을 갖는 것으로 나타났다(R^2=0.659).

Physicochemical environmental factors and enzyme activities were compared between two forest soils in which different species of family Quercoideae were present. Two species are Quercus mongolica and Quercus dentata. Soil pH were ranged 6.2∼6.6 in both forest soils. Moisture content and total organic matter were 1.4 and 1.3 times higher in the surface soil of Q. mongolica forest than the other, repectively. Cellulase activities at the surface soils were 4.71 times and 2.1 times higher than 25㎝ depth soils of Q. mongolica and Q. dentata forest, respectively. Between the surface soil of two vegetational forest, cellulase activity of Q. mongolica forest was 1.69 times than the other. Cellulase activity was correlated with the soluble sugar (R^2=0.623). Protease acitivity was 1.4 times higher in surface soil of Q. mongolica than the other. But, it was 10 fold higher in 25㎝ depth lower soil of Q. dentata forest than Q. mongolica. Phosphatase activities were similar in 25㎝ depth soils of two vegetational forest. But, phosphatase including acidic phosphatase (ACPase), neutral phosphatase (NEPase), alkaline phosphatase (ALPase) showed higher activities in surface soil of Q. mongolica forest compared to Q. dentata forest. Among the 3 kinds of pH dependent phosphatases, ACPase showed close correlationship with protease (R^2= 0.659).
