Abstract : soil incubation experiments were conducted in lab to delineate the effect of soil temperature and soil water content on soil respirations in broad - leaved / korean pine forest ( mountain dark brown forest soil ), dark coniferous forest ( mountain brown coniferous forest soil ) and erman ' s birch forest ( mountain soddy forest soil ) in changbai mountain in september 2001. the soil water content was adjusted to five different levels ( 9, 21, 30, 37 and 43 ) by adding certain amount of water into the soil cylinders, and the soil sample was incubated at 0, 5, 15, 25 and 35 for 24 h the results indicated that in broad - leaved / korean pine forest the soil respiration rate was positively correlated to soil temperature from 0 to 35. soil respiration rate increased with increase of soil water content within the limits of 21 to 37, while it decreased with soil water content when water content was over the range. the result suggested the interactive effects of temperature and water content on soil respiration. there were significant differences in soil respiration among the various forest types. the soil respiration rate was highest in broad - leaved / korean pine forest, middle in erman ' s birch forest and the lowest in dark coniferous forest. the optimal soil temperature and soil water content for soil respiration was 35 and 37 in broad - leaved / korean pine forest, 25 and 21 in dark coniferous forest, and 35 and 37 in erman ' s birch forest. because the forests of broad - leaved / korean pine, dark coniferous and erman ' s birch are distributed at different altitudes, the soil temperature had 4 - 5 variation in different forest types during the same period. thus, the soil respiration rates measured in brown pine mountain soil were lower than those in dark brown forest and those measured in mountain grass forest soil were higher than those in brown pine mountain soil
