对大沽河口湿地3种植被类型5个样点7月份土壤表层微生物生物量(MBC)进行的测定结果表明:MBC含量在五个样点之间的差异显著,其含量依次为养殖池塘地芦苇(样点二)>河边芦苇(样点五)>海草(样点三)>河漫滩(样点四)>碱蓬(样点一)。土壤MBC与土壤含水量、有机质含量之间具有极显著的相关关系;认为在常见的湿地植物中,芦苇是地上生物量和地下生物量都较高的一种植物,有其种植的湿地土壤中MBC的含量较高,表明与其他常见湿地植物相比,芦苇更有利于土壤MBC的积累,对保护湿地和恢复湿地生态系统功能具有重要的作用。
The result of MBC in five samples of three vegetation types in Daguhe wetland in July showed that the content of MBC was significantly different among five sampling sites, (Sample 2)> River Reeds (Sample 5)> Seaweed (Sample 3)> River Flood (Sample 4)> Suaeda (Sample 1). Soil MBC and soil water content, organic matter content has a very significant correlation between; that in common wetland plants, Phragmites australis is aboveground biomass and underground biomass are a higher plant, with its planted wetland soil The content of MBC is higher, indicating that P. reedis is more beneficial to the accumulation of MBC than other common wetland plants, and plays an important role in protecting the wetland and restoring the ecosystem function of the wetland.
