摘要
以亚热带北部皖南丘陵地区小流域定位实地观测为基础 ,研究了农林共存小流域氮素径流输出规律。发现小流域氮素径流输出季节性变化明显。降雨和施肥是影响这一变化的重要因子 ,模拟分析表明 。
Through the research of dynamic change in nitrogen discharge with runoff from a small watershed in southern Anhui Province, we found drastic seasonal changes in nitrogen discharge with runoff, which was attributed to the impact of rainfall and fertilizer use. There is a significant linear relationship between nitrogen discharge and rainfall and the amount of fertilizer applied. Equations for prediction of nitrogen discharge were established based on the study.
