| 摘要: |
| 通过近20多年湖泊水量平衡分析发现，湖泊水位变化主要由湖盆内径流补给量的丰枯决定。进一步分析揭示，呼伦湖地区乃至整个东北地区，本世纪以来随气温升高，降水有增加的趋势。降水增加导致入湖径流量，湖水位上升。呼伦湖本世纪以来的扩张与内蒙古东部地区其他内陆湖泊的变化一致，但这在我国乃至整个亚洲内陆干旱或半干旱区是独一无二的，为此成为这一地区气候变化的指示器。 更多还原 |

| Abstract: |
| With the warming global climate, the water level record partly restored from historical data of Hulun Lake located in Inner Mongolia, China, Has shown apparently expansion which is contrary to most inland lake evolution in Central Asia recently. Studies of the lake water budget in 1959 - 1983 showed that the lake level fluctuation was mainly depended on surface runoff change. More detailed analysis of the surface runoff showed that runoff increase and water level rise of the lake were closely related to precipitation increase with the rise of temperature in lake region and Northeast China. Above changes of Hulun Lake are similar to Inner Mongolia, but these lakes evolution is opposited to that of most inland lakes of Aisa. It becomes an indicator of the climate change in this region. |
