本数据集包括了多枝柽柳和梭梭这两种荒漠植被在不同地下水位环境下光合、蒸腾和气孔导度变化的多日的不同时间的实验观测数据，主要研究干旱区典型植物与大气间水碳交换过程机理。数据属于生理生态学、自然地理学、水文学范围。数据采集地点中国科学院寒区旱区环境与工程研究所临泽试验站周围，海拔：1 380米。\n数据文件：光合数据集.xls，包含1个表，度量单位：“地下水位”量纲：m；“PAR”量纲：umol·m﹣²·h﹣¹ ；“PAR标准差”量纲：umol·m﹣²·h﹣¹；“光合速率”量纲：umol·m﹣²·h﹣¹；“光合速率标准差”量纲：umol·m﹣²·h﹣¹；“蒸腾速率”量纲：mmol·m﹣²·h﹣¹；“蒸腾速率标准差”量纲：mmol·m﹣²·h﹣¹；“蒸腾速率”量纲：mmol·m﹣²·h﹣¹；“蒸腾速率标准差”量纲：mmol·m﹣²·h﹣¹。\n
", "ds_source": "仪器：CI-340便携式光合仪，观测方法：在观测点，选择2-3株植物，每株植物2-3个叶片进行观测，最终结果为数据的平均值并给出标准差。
