Paq means the percentage content of aquatic plants in peat sediment and is an indicator of moisture, ACL means average carbon chain length and is an indicator of temperature.<br><br>
列项：
(1) 深度（cm）
(2) 年龄（yr BP，距今年数）
(3) Paq
(4) 水生植物烷基碳链比例（ACLP_aq）= (C₂₃ + C₂₅) / (C₂₃ + C₂₅ + C₂₉ + C₃₁)
平均碳链长度（ACL）= (21×C₂₁ + 23×C₂₃ + 25×C₂₅ + 27×C₂₇ + 29×C₂₉ + 31×C₃₁ + 33×C₃₃) / (C₂₁ + C₂₃ + C₂₅ + C₂₇ + C₂₉ + C₃₁ + C₃₃)
本数据集揭示了中亚干旱区全新世的湿度与温度演变特征。其中，Paq（Percentage of Aquatic Plants in Peat Sediment）指泥炭沉积物中水生植物的占比，为湿度代用指标；ACL（Average Carbon Chain Length）指平均碳链长度，为温度代用指标。
