2008年5月31日至7月13日期间，在中游干旱区水文试验区临泽草地加密观测区PR2样方和PR2样带进行了土壤水分剖面的逐日观测。测量临泽草地站不同下垫面、不同深度土壤水分变化，为土壤水分时空变化分析以及土壤水分的热惯量法反演提供数据。\n
\nPR2样方布置在临泽草地加密观测区样方A附近，为3Grid×3Grid，90m×90m样方，具体坐标信息请参见元数据“黑河综合遥感联合试验：临泽草地加密观测区样方样带布置”。PR2样带布置为一条线，穿越苜蓿地，大麦地及盐碱地等不同地表类型。测量仪器为PR2，可以提供土壤剖面10cm、20cm、30cm、40cm、60cm及100cm处的土壤水分数据。其中6月3日，6月6日，6月8日，6月10日，6月13日，6月21日，6月27，6月28日，6月29日，7月3日，7月12日没有进行观测。\n
\n本数据集包括不同日期下测量的土壤剖面水分Excel数据表格。样方分布请参见元数据：“黑河综合遥感联合试验：临泽草地加密观测区样方样带布置”

The changes of soil moisture at different underlying surfaces and depths at Linze grassland station were measured to provide data for the analysis of temporal and spatial changes of soil moisture and the inversion of soil moisture by thermal inertia method.\n
\nPR2 quadrat is arranged near quadrat a in Linze grassland intensive observation area, which is 3grid × 3Grid，90m × 90m quadrat. For specific coordinate information, please refer to the metadata \"Heihe comprehensive remote sensing joint test: layout of quadrat transect in Linze grassland intensive observation area\". PR2 transect is arranged as a line, crossing different surface types such as alfalfa land, barley land and saline alkali land. The measuring instrument is PR2, which can provide soil moisture data at 10cm, 20cm, 30cm, 40cm, 60cm and 100cm of soil profile.
