中文摘要：

以青藏和蒙新两大湖区代表的我国寒区和旱区湖泊为对象, 通过各湖区典型湖泊与气候变化的时间序列分析, 揭示了湖泊与气候变化的动态关系;通过区域尺度湖泊面积的阶段性变化过程与区域气候变化的关系, 分析了湖泊变化的区域气候影响背景. 结果表明： 位于我国寒区和旱区的湖泊对气候变化具有高度敏感性, 从气候的角度来看, 内蒙古的湖泊受降水影响较为明显, 新疆湖泊总体上受降水影响显著, 但由于冰川的存在气温对湖泊也有一定影响. 青藏高原典型湖泊变化的分析表明, 降水、气温对不同湖泊有着不同的影响, 在区域上湖泊与气候的变化关系表现的更为复杂, 在降水增加、气温上升的情况下由于升温引起的湖泊蒸发效应超过降水增加导致的补给影响, 湖泊总体趋于萎缩.

英文摘要：

The study objects in this work are lakes in the Tibetan Plateau, Inner Mongolia and Xinjiang regions. Dynamic relations between lake and climate change are revealed through analyzing the variations of typical lakes and climate change in each lake regions. The relationship between variations in area of lake and climate change in phase is analyzed in a regional scale. It is found that the lakes locating in the cold and the arid regions of China have highly sensitivity to the climate change. The lakes in the Inner Mongolia lake region are affected mainly by precipitation in view of climate. As a whole, precipitation has more noticeable impact on the lakes in the Xinjiang lake region. But Air temperature also has definite impact due to glaciers in the region. Precipitation and air temperature have the different effects on different lakes on the Tibetan Plateau. The relationship between lake and climate change is even more complicated in a regional scale. The lakes, as a whole, tend to shrink under the conditions of precipitation increasing and air temperature rising on the Tibetan Plateau.
