在2012年中游航空遥感试验开展期间，在中游的不同下垫面进行了“密闭箱-气相色谱法”测量土壤呼吸，选取了农田、果园、湿地、荒漠、戈壁、沙漠6个不同的下垫面进行测量。\n

同化箱由两部分组成：底座和箱体。底座采用PVC材料制成，下端埋于土壤中。箱体部分是由不锈钢制的立方体，一边开口。测量时将箱体盖在底座上，利用注射器抽取箱内的气体样品，将抽取的气体注射到气体采样袋中，运回实验室分析CO2的浓度，在中科院植物所利用气相色谱法进行测量。根据浓度的变化来计算土壤呼吸速率。每个测量点设3个重复。在盖上箱子密封5分钟后开始采第1次样，然后每间隔10分钟采一次样，总共采4次。\n

During the aerial remote sensing experiment in the middle reaches in 2012, the \"closed box gas chromatography\" was used to measure soil respiration on different underlying surfaces in the middle reaches, and six different underlying surfaces including farmland, orchard, wetland, desert, Gobi and desert were selected for measurement.\n

\n

Observation instrument:\n

\n

Assimilation box, Institute of environment and engineering, cold and arid areas, Chinese Academy of Sciences.\n

\n

Measurement method:\n

\n

The assimilation box consists of two parts: base and box. The base is made of PVC material, and the lower end is buried in the soil. The box part is a cube made of stainless steel with an opening on one side. When measuring, cover the box on the base, use the syringe to extract the gas sample in the box, inject the extracted gas into the gas sampling bag, transport it back to the laboratory to analyze the CO2 concentration, and measure it by gas chromatography in the Institute of Botany, Chinese Academy of Sciences. The soil respiration rate was calculated according to the change of concentration. Set 3 repetitions for each measuring point. The first sample shall be taken after the box is closed for 5 minutes, and then the sample shall be taken every 10 minutes, a total of 4 times.\n
