摘　　要：晚第四纪气候演变有3个主要阶段:最后间冰期、大理冰期和冰后期。最后间冰期分3个暖期和2个冰期,最高温高于现在4℃。大理冰期分3个副冰期和2个副间冰期,最低温低于现在8—13℃;但冰暖变幅7—8℃的气候旋回可达10个。冰后期气候变化分4个阶段,冷暖变幅仅5-6℃。气候变化全过程表明,未来气候趋向变冷,人为影响只能起减缓或促进作用,而不能转变总趋向。There were three main stages in Late Quaternary climate changes: last interglacial, Dali-ice age and post glaciation. The last interglacial can be divided into three warmer stages and two colder stages; the highest temperature was 4℃ higher than now. Dali-ice age can be divided into three stadial periods and tow interstadial periods; the lowest temperature was 8-13℃ lower than present . But there were about 10 warmer and colder climatic cycles with amplitude of 7-8℃ . The climate changes during the post glaciation also can be divided into four stages, but the colder and warmer changing range was only 5-6℃. The total process of the climatic change shows that the climate in the future will be colder .Although the influences of mankind will be reducing the cold level of climatic change. It can not turn round after all direction of climatic change.
