西北干旱地区凝结水试验研究

Experimental study on the condensation water in arid area, Northwestern China

采用称重法 ,分别在非冻结期和冻结期 ,对不同土质的土样进行凝结水观测试验 ,分析讨论凝结水发生的条件、凝结水发生的时间、凝结水形成的主要影响因素、积雪条件下的凝结水、凝结水的数量及其变化以及凝结水的生态环境意义 ,研究成果对于认识干旱地区凝结水的形成机制及其生态环境意义具有重要价值。

The weighing method is adopted in condensation of the water observation The condensation water for the different kinds of soil samples are observed during the freezing period and non freezing period respectively The necessary conditions and time occurring the condensation water, the main influence factors forming the condensation water, the condensation water under the accumulated snow circumstances, the amount of the condensation water and its variation, and the eco environmental significance of the condensation water are all analyzed and discussed The research achievements have great significance to recognize the formation mechanism of the condensation water and the eco environmental benefit of the condensation water in the arid areas, Northwestern China
