| 摘 要： | 在库布齐沙漠测定了人工生物结皮层的养分含量和颗粒物质的组成，结果表明：采取人工接种技术形成的生物结皮层同样具有养分富集的特征，速效氮、全氮、速效磷、全磷和有机质含量分别比固定沙地增加5．5％、70．0％、59．4％、53．96％和48．9％。与天然形成的生物结皮层养分含量相比，人工生物结皮层各养分（速效磷除外）含量较低，颗粒组成含量和天然形成的生物结皮层颗粒组成含量几乎一致，说明人工接种技术形成的生物结皮层颗粒物质组成和天然生物结皮相同。

| Abstract: | The nutrients content and particle matter composition of artificial biological soil crusts were studied in Kubuqi desert.The results showed that artificial biological soil crusts had nutrients content accumulation phenomenon.Compared with the fixed sand soil,available nitrogen content in artificial biological soil crusts was increased by 5.5%,total nitrogen content was increased by 70.0%,available phosphate content was increased by 59.4%,total phosphate content was increased by 53.96%,organic matter content... |
