本文以艾比湖湿地自然保护区内柽柳群落区、盐节木群落区和芦苇群落区等3种典型植被聚居区土壤为研究对象,通过比较3块样地土壤中细菌、放线菌、真菌的分布情况,了解艾比湖湿地土壤的质量与状况。结果表明:柽柳群落区土壤中微生物分布最多,芦苇群落区次之,盐节木群落区最少,各类微生物的分布情况与土壤含水量、pH、盐度及有机质含量无显著相关性。细菌数量在3个样地中随土层深度递增有增加的趋势,放线菌与真菌呈现先增加后减少的趋势。这显示了3块样地中柽柳群落区土壤活性最高、肥力最好,盐节木群落区最差,因此,柽柳及芦苇等植物对改良该区域土壤质量有很大的潜在价值。
In this paper, the soil of three typical vegetation habitats, including Tamarixtiveae community, Salix japonicus community and Phragmites australis community in Aibi Lake Wetland Nature Reserve, was selected as the research object. By comparing the characteristics of bacteria, actinomycetes, fungi Distribution, understand the quality and status of the soil in Lake Aibi wetlands. The results showed that the distribution of soil microorganisms was the most in the soil of Tamarix chinensis community, followed by the community of Phragmites communis, and the distribution of microorganisms was the least. There was no significant correlation between the distribution of microorganisms and soil moisture content, pH, salinity and organic matter content. The number of bacteria in the three plots increased with soil depth increasing tendency, actinomycetes and fungi showed the first increase and then decrease. This showed that the tadpa grass community had the highest soil activity, the best fertility and the worst community structure in the three plots. Therefore, plants such as Tamarix and Reed had great potential to improve the soil quality in this area.
