Key Points

  • To compare the response differences of terminal and throughflow lakes to climate change in the Selincuo Lake basin.
  • Utilized remote sensing imagery and high-resolution meteorological data
  • Applied water body index method to extract lake area changes
  • Developed evaluation metrics for lake response synchronization and regulation capacity
  • Significant warming and wetting observed since 1988, with a warming rate of 0.4 °C per decade
  • Rainfall increased by 25.0 mm per decade, leading to a total lake area increase of 25.2%
  • Selincuo Lake showed the most significant expansion at 42.9%, characterized by three distinct phases

Abstract

色林错流域是西藏最大的内流湖水系,流域内及邻近地区有20多个湖泊组成的封闭湖泊群。近年来,色林错持续扩张,影响区域人居环境和生态。本文基于长系列遥感影像与高分辨率气象数据,采用水体指数法提取湖泊面积,构建湖泊响应同步性与调蓄能力评价指标,比较不同尾闾湖与过流湖对气候变化响应的差异。结果显示,该地区经历了显著的变暖增湿过程,1988年以来,升温速率为0.4 ℃ (10 a)-1,降水量增长速率为25.0 mm (10 a)-1,区域湖泊总面积增加25.2%。其中,尾闾湖大多呈扩张趋势,色林错扩张最为显著,增幅达42.9%,其扩张过程呈现三阶段特征:1988–1999年降水较少,气温较低,湖泊缓慢扩张(3.4 km2 a-1);2000–2013年降水显著增加、气温明显升高,湖泊快速扩张(36.5 km2 a-1);2014年以来降水、气温增幅减小,湖泊扩张速率明显放缓但仍在持续(7.9 km2 a-1)。过流湖的年际面积变幅小于5%,且更同步。湖泊年内面积峰值的出现时间集中于8–10月。色林错上游6个大型过流湖可滞留1.6–3.6亿m³的水量,多年平均约2.4亿m³,发挥了重要的削峰与调蓄作用。
