摘要
土壤温度上升可能会引起土壤产生过量的ＨＮＯ３，而过量的ＨＮＯ３在酸性土壤中将导致Ａｌ（３＋）浓度的升高和盐基阳离子的流失，使养分失调，细根坏死。土壤温度上升还可能会改变土壤有机质动力学、土壤水文学和土壤物理学，从而改变森林生境特征，影响森林的正常生长。
Increased soil temperature may induce surplus HNO3 which will increase the concentration of Al(3+) in acid soil and the leaching of bole ions from the soil, leading to nutrient imbalance and rootlet mortality. Moreover, increased soil termperature may change soil organic metter dynamics, soil hydrogy and soil physics, thus changing the characteristics of forest habitats and influencing the forest normal growth.
