摘　　要：一般的土壤空气采集装置在藏北除不同程度存在着结构复杂、不便携带、土壤固液态杂质干扰等问题外,适用性和经济性也受到了极大的限制。基于"原位防扰动、隔离降误差、手动便携更实用"的思想,介绍了一种呈管状多层次嵌套结构且具有防水透气采气窗的便携式土壤空气原位采集器,该装置能抽掉残留空气又能防止土壤水分入渗及土壤固体组分的干扰,且工艺简单、便携易用、经济耐用,适用于藏北高寒草原的复杂自然环境。In the alpine-cold grassland of Northern Tibetan Plateau, ordinary soil air collectors would show a limita- tion of suitability and economic, besides the deficiencies of complex structure, inconvenience to carry, interfer- ences from soil impurities, etc. Based on the thought of ＂collection in-situ to clamp disturbance, impurity removal to control errors and portable for more practicality＂, a portable soil air in-situ collector with a tubular multi-level nested structure and a waterproof and breathable transom was presented, which only has minimally invasive on soil structure, can effectively remove the outer air, reduce the impact of soil moisture and soil fine particles of solid matter, and is applicable under the complex conditions of the grassland, Northern Tibetan Plateau.
