　　水分和氮素是温带草地乃至整个陆地生态系统的两个重要限制性因子。全球变化背景下，降水与大气氮沉降都将发生明显的变化，并相互影响与制约着彼此对生态系统的作用效应。水氮交互作用对草地碳、氮循环过程的影响及其对未来气候变化的可能反馈是目前草地全球变化研究领域的重点关注内容。董云社研究小组近几年一直围绕上述内容开展相关的野外试验研究，在草地土壤呼吸，N20排放速率，植被NPP，凋落物分解，土壤碳库以及土壤微生物等对水、氮输入变化的响应方面取得了一定的认识，相关成果分别在Clean–Soil, Air, Water，JES, JAL, JIA，JPAM等刊物上发表，其中发表在JES上的文章为当期封面论文。
