| 摘 要： | 根据1972年陆地卫星MSS,1992年TM与1999年ETM+3个时相的遥感数据信息,对西藏色林错湖面增长进行动态分析后,发现近30a来湖面逐渐扩大,从1707km2增大到了1823km2.本文分别从气象学、构造地质学及高原隆升等方面分析了湖面扩大的原因.认为很有可能是由于温室效应,使得气温上升,冰雪、冰川融化和冻土软化释放水注入色林错,进而引起湖面增长.并就其所揭示的环境信息进行了初步探讨. |

| Abstract: | According to the remote sensing data obtained in 1972,1992 and 1999, it is found that the Selincuo lake has expanded. The area of the lake has expanded from 1 707 km 2 to 1 823 km 2. Based on an analysis of such factors as meteorological phenomena, tectonic activity and uplifting of Qinghai-Tibet plateau, this paper explains the reasons for the lake expansion. It seems that the greenhouse effect plays the major role. With the rising of the temperature, the thawing of the glacier and the softening of the frozen earth result in the formation of free water, and then the water flows into the Selincuo Lake, leading to the expansion of the lake. |
