| 摘 要： | 土壤凝结水是半干旱地区生态系统重要的水源,为阐明毛乌素沙地臭柏(Sabina vulgaris)冠层下土壤表层5cm凝结水的水汽来源,应用自制凝结试筒于2008年9—10月在毛乌素沙地开发整治研究中心院内开展试验。结果表明,毛乌素沙地土壤表层凝结水由吸湿水、大气水汽凝结水和土壤水汽凝结水组成;大气中的水汽总是先于土壤中的水汽到达和离开表层5cm土壤;大气中水汽对土壤表层5cm凝结水的贡献率小于土壤水汽的贡献率,9月上旬至中旬大气中水汽和土壤水汽的贡献比为2:5,9月下旬至10月中旬为3:10;单日凝结量和蒸发量呈现显著的线性关系。 |

| Abstract: | Condensation water in soil is an important water source for semiarid ecosystems.In order to clarify water vapor source of condensation water in the upper 5 cm soil layer under canopy of Sabina vulgaris in Mu Us Sandland,a homemade test tube was used to operate study in the yard of Mu Us Sandland Development and Research Center from September to October 2008.The results indicate that there are three kinds of water vapor source:air vapor directly adsorbed by soil,condensation water from air and water vapor fr... |
| Keywords: | Mu Us Sandland canopy of Sabina vulgaris soil condensation water water source |
