库布齐沙地土壤的生物学活性研究

Study on Soil Biological Activities in Hobq Sand Dune

测定分析了库布齐沙地土壤的酶活性、呼吸作用强度和微生物生物量，结果表明：沙地结皮层有较高的生物学活性，它们的垂直分布有地区独特性，并与其它肥力因素相关．

The activities of enzyme、biomass of microorganism and intensity of respiration in Hobq sand dune of NeiMongol have been determined,the results showed:the biological activities in the crust of sand dune was highest,the vertical distribute of biological activities in sand dune were peculiar to others area,and the those activities were related to soil fertility factors in sand dune.
