| 摘 要： | 本文对鄂尔多斯沙漠生物结皮作用进行了初步研究,结果表明结皮层的机械组成以细沙和粗粉沙为主,而流沙以粗沙和细沙为主;生物结皮层影响降水的再分配作用,并影响入渗水的蒸发规律;生物结皮层具有较好的保水特性和养分富集作用。

| Abstract: | The function of desert microbiotic crusts in Erdos was analyzed,the results ahowed that: microbiotic crusts consist of fine sand and thick powder sand,but differs with the wind-drift sand,wind-drift sand are coarse sand and fine sand;microbiotic crusts influence the rainfall distribution again and effect on the evaporation of infiltration moisture;microbiotic crusts has the power of water conservation and the function of enrichment of nutrients. |

| Keywords: | Microbiotic crust characteristic of moisture physico-chemical properties |
