基于不同植被类型,探讨辽河三角洲湿地不同植被类型中土壤微生物中细菌、放线菌和真菌三大类微生物数量以及土壤微生物量碳状况。三类群微生物的分布都表现为表层大于其它两层。对不同植被类型而言土壤细菌的数量是:草地、森林、柽柳和碱蓬的数量相对较高,而翅芦苇和裸滩数量相对较低。对不同植被类型而言土壤放线菌的数量是:草地、森林和柽柳的数量相对较高,而芦苇、翅芦苇、翅碱蓬和裸滩数量相对较低。对不同植被类型而言土壤真菌的数量是:草地、森林、柽柳和玉米的数量相对较高,而翅芦苇、翅碱蓬和裸滩数量相对较低。对于土壤微生物量碳垂直层次上变化趋势大致相似,表层含量稍高于其它两层。对于不同植被类型而言,土壤微生物量碳含量是柽柳>草地>芦苇>玉米>森林>碱蓬>翅碱蓬>翅芦苇。
Based on the different types of vegetation, the quantity of bacteria, actinomycetes and fungi in soil microorganisms and soil microbial biomass carbon in different vegetation types in Liaohe Delta was discussed. The distribution of the three groups of microorganisms showed that the surface layer was larger than the other two layers. The number of soil bacteria for different vegetation types is: the number of grassland, forest, Tamarisk and Suaeda is relatively high, while the number of winged reeds and bare beaches is relatively low. The number of soil actinomycetes for different types of vegetation is: the number of grassland, forest and tamarisk is relatively high while the number of reed, winged reed, Suaeda scrub and bare beach is relatively low. The number of soil fungi for different types of vegetation is: the number of grassland, forest, tamarisk and maize is relatively high, while the number of winged reed, Suaeda sipah and bare beach is relatively low. For the vertical variation of soil microbial biomass carbon, the trend is similar, with the surface content slightly higher than the other two layers. For different types of vegetation, soil microbial biomass carbon content was Tamarix> grass> reed> corn> forest> soda ash> Suaeda spp> fin reed.
