模拟污水添加对闽江河口湿地甲烷排放的影响

In order to study the effect of sewage discharge on methane emission from estuarine wetland, mesocosms was constructed indoor and the sewage addition experiment was carried out to explore the effect of sewage addition on methane emission from the wetland with and without vegetation cover. The effect of sewage discharge on methane flux was not significant while the effect of vegetation cover was significant. Vegetation coverage, redox potential (EH) and phosphate content in sewage are the key factors affecting methane emission from wetlands.
