| 摘 要： | 从生物地球化学循环的观点出发 ,研究了N循环的人为干扰与土壤酸化的关系 ,并探讨了N循环扰动下导致土壤酸化的机理。在土壤酸化中 ,人类对N循环干扰起作用最大的是对大气中NOx 排放的影响以及对N固定的影响 ;前者通过酸雨导致土壤酸化 ,后者则通过施肥导致土壤酸化。

| Abstract: | The relation between soil acidification and nitrogen cycle disturbed by man made factors was studied from the viewpoint of biogeochemical cycle, and the mechanism of soil acidification induced by disturbed nitrogen cycle was probed. For soil acidification, the most important effect of human activities on nitrogen cycle is the effect on NO x (soil acidification induced by acid rain) and fixation of nitrogen (soil acidification induced by fertilization). |

| Keywords: | soil acidification nitrogen cycle man made factor |
