  1. 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

    文摘:為了研究壤溫度和壤含水量對闊葉紅松(山地壤) 、雲冷杉針葉(山地針葉壤)和岳樺(生草)的壤呼吸的影響,於2001年9月在長白山進行了壤實驗.利用增加壤樣柱的含水量,將壤含水量分為9 , 、 21 、 30 、 37和43 5個等級,壤樣品分別在0 、 5 、 15 、 25和35的溫度下保持24小時.闊葉紅松壤在0 ( 35范圍內,壤呼吸速率與溫度呈正相關.在一定的含水量范圍內( 21 ( 37 ) ,壤呼吸隨含水量的增加而升高,當含水量超出該范圍,壤呼吸速率則隨含水量的變化而降低.壤溫度和水分對壤呼吸作用存在明顯的交互作用.不同類型壤呼吸作用強弱存在顯著差異,大小順序為闊葉紅松>岳樺>雲冷杉針葉.紅松闊葉壤呼吸作用的最佳條件是壤溫度35 ,含水量37 ;雲冷杉針葉下的山地針葉壤呼吸作用的最佳條件是25 , 21 ;岳樺壤呼吸作用的最佳條件是35 ,含水量37 .但是,由於長白山闊葉紅松,雲冷杉和岳樺處在不同的海拔帶上,同期不同類型壤溫度各不相同,相差4 ~ 5 ,所以野外所測的同期的山地針葉呼吸速率應低於暗棕色森林土呼吸速率,山地生草呼吸速率應高於山地針葉的呼吸速率.圖2表1參25
