为探究洞庭湖区典型沟塘反硝化脱氮规律,本研究于2020年9月至2021年8月,采集洞庭湖流域不同类型沟塘上覆水样及表层柱状沉积物,通过近似原位的培养方法并结合膜进样质谱法测定了不同沟塘的反硝化速率。结果表明:沟塘反硝化速...展开更多 为探究洞庭湖区典型沟塘反硝化脱氮规律,本研究于2020年9月至2021年8月,采集洞庭湖流域不同类型沟塘上覆水样及表层柱状沉积物,通过近似原位的培养方法并结合膜进样质谱法测定了不同沟塘的反硝化速率。结果表明:沟塘反硝化速率存在显著的时空异质性,反硝化速率范围为22.10~238.02μmol·m–2·h–1,均值为91.12μmol·m–2·h–1,春、夏季节的反硝化速率大于秋...
