, 2009 2004年5-10月,对三江平原典型小叶章草甸和小叶章-苔草沼泽化草甸群落优势植物小叶章的氮素累积与分配特征进行了研究.结果表明:典型草甸和沼泽化草甸小叶章地上器官及枯落物的全氮含量在生长季均呈递减变化,符合指数衰减模型(T_N=Aexp(-t/B_1)+B_2,R~2≥0.94),二者根的全氮含量波动较大,且在生长高峰期前的15～30 d存在一个明显的养分蓄积时期.不同器官和枯落物的氮累积量和累积速率(V_N)季节变化明显,且典型草甸小叶章地上部分的氮累积量和V_N明显高于沼泽化草甸,而地下部分则相反.

, 2017 农田生态系统作为温室气体排放源之一在全球碳氮循环中起到了重要作用。新疆绿洲农田是干旱区典型的灌溉农田生态系统，受人类活动的强烈影响，农田土壤CO2/N2O排放强度远高于同区域的其他生态系统，研究绿洲农田土壤CO2/N2O排放特征及调控措施具有重要的理论及实践意义。论文以干旱区绿洲棉田为研究对象，采用静态箱-气相色谱法阐明了绿洲棉田土壤CO2/N2O排放特征及主要影响因素，假设覆膜增加了土壤CO2排放、减少了土壤N2O排放，施肥促进了土壤CO2/N2O排放 ...
