2008年5月25日和6月22日在临泽站加密观测区开展荒漠过渡带样方调查。\n调查的主要内容：\n
\n1．土壤剖面；土壤分层：0-10cm，10-20cm，20-30cm，30-40cm共计4层，东西样带和南北样带各1各剖面。观测项目：土壤水分和土壤温度。观测仪器与采样数量：土壤水分观测用环刀（体积50cm^3），每层1次；土壤温度观测用美国6310针式土壤温度计（15cm），每层2个重复。数据存储：Excel。测量时间：2008-05-25。\n
\n2．生物量调查；观测项目：生物量（干重和鲜重），有采样时照片。观测方法：收割法。观测地点：LY07样方周围，6个生物量收割法采样样方。红柳和沙拐枣单株植物较大，无法采用收割法，只按比例，将其中的一支或者两支剪下；其余采样样方均为50cm×50cm。数据存储：Excel。测量时间：2008-06-22。\n
\n3．植被覆盖度；测量方法：对角线法，即分别估测两条对角钱上植被的覆盖度（重叠部分只算1 次），按算术平均计算样地的总覆盖度。覆盖度观测与生物量观测同时进行。数据存储：Excel。测量时间：2008-06-22。

\n1. Soil profile; Soil stratification: 4 layers in total, 0-10cm, 10-20cm, 20-30cm and 30-40cm, with 1 section in the East-West sample zone and 1 section in the North-South sample zone. Observation items: soil moisture and soil temperature. Observation instruments and sampling quantity: ring knife for soil moisture observation (volume 50cm ^ 3), once per layer; American 6310 needle soil thermometer (15cm) is used for soil temperature observation, with 2 repetitions in each layer. Data storage: Excel. Measurement time: May 25, 2008.\n
\n2. Biomass survey; Observation items: biomass (dry weight and fresh weight), with photos during sampling. Observation method: harvesting method. Observation site: around ly07 quadrat, 6 quadrats were sampled by biomass harvesting method. The single plant of red willow and Calligonum mongolicum is large, so the harvesting method cannot be adopted. Only one or two of them shall be cut according to the proportion; Other sampling quadrats are 50cm × 50cm。 Data storage: Excel. Measurement time: June 22, 2008.\n
\n3. Vegetation coverage; Measurement method: diagonal method, that is, estimate the vegetation coverage on the two diagonals respectively (the overlapping part is calculated only once), and calculate the total coverage of the sample plot according to the arithmetic average. Coverage observation and biomass observation were carried out at the same time. Data storage: Excel. Measurement time: June 22, 2008
