图3. 氮(N)输入对盐沼湿地可溶性有机碳(DOC)产生和释放的影响。外源氮输入通常伴随着DOC输入, 影响到植被生长, 通过植物残体和微生物生物量改变了土壤和水体中DOC的含量, 从而也会干扰CO2和CH4的排放以及DOC输出。
Fig. 3. Effect of nitrogen (N) input on production and release of dissolved organic carbon (DOC) in a salt marsh. N input is generally accompanied by DOC input, which affects vegetation growth. It alters DOC content in soil and water through plant litter and microbial biomass, thus also interfering with CO2 and CH4 emissions and DOC output.
