通过对科尔沁沙地不同类型生物结皮土壤微生物量碳的测定分析,表明:土壤微生物量碳随土壤深度的增加而减少。有结皮的沙地微生物量碳含量较高。不同类型结皮中土壤微生物量碳关系不同。这对于研究本地区的环境保护、水土保持以及防风固沙等方面意义重大。
Through the analysis of soil microbial biomass carbon in different types of biological crusts in Horqin sandy land, it showed that soil microbial biomass carbon decreased with soil depth. The sandy soil had higher carbon content in crusted sandy soil. Different types of crust soil microbial biomass carbon relationship is different. This is of great significance for studying the environmental protection, soil and water conservation and windbreak and sand fixation in this area.
