摘要: 岐山剖面孢粉分析表明,黄土高原东南部晚更新世植被与气候变化可分为7个阶段和13个小阶段。其中末次冰期的3个冷干阶段和2个温湿阶段被分别命名为秦家寨、岐山、坡头冰阶和尚家坡、杨家湾间冰阶。冰阶的植被以温带森林草原为主,间冰阶的植被以落叶阔叶林为主。

Abstract: Sporo-pollen analysis in Qishan section shows that the change of vegetation and climate of the Late Pleistocene can be divided into six stages and thirteen sub-stages in the southeast part of the Loess Plateau. Three cold-dry stages and two temperate moist stages of last glacial period are named Qinjiazhai glacial staircase, Qishan glacial staircase, Potou staircase, Shangjiapo interglacial staircase and Yangjiawan interglacial staircase respectively. Forest-steppe consisting of Ulmus, Quercus and herb indicating cold and semiarid climate was dominant during glacial periods, and mean annual rainfall was 400-500 mm at that time. Deciduous broadleaf forest consisting of Quercus, Julans and Pterocarya etc. representing temprate moist climate prevailed during interglacial periods and interglacial staircases, and mean annual rainfall was 600-700 mm at that time.
