图4 青藏高原及其周边山地基于地貌-冰面剖面形态模型（Excel流线模型、GlaRe、PaleoIce）和物质平衡-冰川动力耦合模型的稳态模拟方式（2-D冰流模型）估算的不同冰川发育时期古气候参数的案例研究（基于地貌-冰面剖面形态模型的古气候参数估算方法包括P-T模型、LR模型、ΔT-ΔP在ELA处经验公式、EMB和DDM模型。基于2-D冰流模型的古气候参数主要通过不同的ΔT-ΔP组合确定。MIS-深海氧同位素阶段；LGM-末次冰期全盛期；LD-末次冰消期；LG-晚冰期；EH-早全新世；NEO-新冰期；LIA-小冰期）

Fig. 4 Summary of the palaeo-climate reconstruction studies for various glacial stages on the Tibetan Plateau and its surrounding mountains based on the landform-ice surface profile models （Excel flowline model， GlaRe， and PaleoIce） and the coupled mass balance-glacial dynamic model （2-D ice flow model）. For the studies using the landform-ice surface profile models， the palaeo-climate information has been estimated based on the P-T model， LR model， the ΔT-ΔP empirical relationship at ELA， as well as the EMB and DDM models.
