为探讨半干旱区不同下垫面对土壤吸湿凝结水量的影响,采用称重法研究了毛乌素沙地开发整治研究中心院内臭柏群落、油蒿群落和裸地三种下垫面土壤吸湿凝结水量的变化特征。结果表明:植被可以改变试验点的温湿度,裸露沙地凝结量小于有植物区;臭柏群落形成吸湿凝结水最多,油蒿次之,裸地最少;同一下垫面中的凝结水量,地表以上20cm处的>10cm处>地表处。
In order to discuss the influence of different underlying surface on the amount of soil moisture absorption and condensation water in semi-arid area, the moisture absorption and condensation capacity of three kinds of underlying surface of Sabina vulgaris, Artemisia ordosica community and bare land in Mu Us Sandland Development and Remediation Research Center The changing characteristics. The results showed that: the vegetation could change the temperature and humidity of the test point, the condensation amount in the bare sand was less than that in the plant area; the oyster condensed water was the most in the Sabina vulgaris community, the second was the Artemisia ordosica, followed by the bare soil; the amount of condensation water in the same underlying surface, Above> 20cm at> 10cm at the surface.
