摘要:

湖泊作为干旱区气候变化的敏感指示器,其时空动态变化规律及驱动因素的准确识别,对区域水资源的科学配置与高效利用具有重要意义。基于1990—2024年多源遥感数据和气象资料,结合归一化水体指数(NDWI)及人工解译校正方法,系统提取并编目昆仑山北坡湖泊信息,分析其35 a的时空动态变化规律及驱动因素。结果表明:(1) 1990—2024年昆仑山北坡湖泊数量和面积均显著增加,湖泊数量由125个增至396个,增幅达216.80%;面积由1439.18 km2增至2614.22 km2,增幅为81.65%。(2) 空间上,车尔臣河流域湖泊面积增加最为显著,扩大约3.6倍(净增138.86 km2);和田河流域湖泊面积增加约1倍(净增46.98 km2);库木库里盆地湖泊面积增幅73.20%(净增989.20 km2);从海拔维度上看,山区湖泊面积净增1144.47 km2,显著高于平原区湖泊的30.57 km2。(3) 时间序列上,湖泊面积变化呈现明显阶段性:1990—1995年呈下降趋势,年均减少23.26 km2·a-1;1995年后持续增加,其中1995—2000年增幅高达52.56 km2·a-1;2000—2005年年均增幅为39.90 km2·a-1;2005年后各阶段变化速率略有波动,但总体保持持续增长趋势。(4) 昆仑山北坡山区湖泊增加主要归因于气温上升引发的冰雪消融及降水增加的共同驱动。过去35 a,山区水储量增加明显,同期气温增幅达35.30%、降水量增加13.18%,这一特征在车尔臣河与库木库里盆地表现尤为显著。相比之下,平原区湖泊的波动性变化主要由气温升高导致的蒸发潜力增加与降水量波动共同作用所致。研究结果为昆仑山北坡区域水资源管理与气候响应评估提供了重要的科学依据与政策参考。

Abstract:

As sensitive indicators of climate change in arid regions, lakes provide critical insights into regional water resource allocation and utilization. Thus, the accurate identification of their spatiotemporal dynamics and driving mechanisms is of great significance. Employing multisource remote sensing and meteorological records from 1990 to 2024 and integrating the normalized difference water index with manual interpretation and correction, this study systematically extracted and cataloged lake dynamics on the northern slope of Kunlun Mountains. The spatiotemporal evolution of lakes and their driving mechanisms over the past 35 years were subsequently analyzed. The results indicate the following: (1) From 1990 to 2024, the number and total area of lakes on the northern slope of Kunlun Mountains increased significantly. While the number of lakes increased from 125 to 396 (216.80% increase), the total lake-area expanded from 1439.18 km2 to 2614.22 km2 (81.65% increase). (2) Spatially, the most significant lake-area expansion occurred in the Cherchen River Basin, where the lake-area increased by ~3.6 times, corresponding to a net gain of 138.86 km2. This was followed by the Hotan River Basin, where the lake-area approximately doubled, with a net gain of 46.98 km2, and the Kumukuli Basin, where the lake-area increased by 73.20%, corresponding to a net gain of 989.20 km2. Regarding elevation, mountain lakes exhibited a net area increase of 1144.47 km2, which was substantially higher than the 30.57 km2 increase observed for plain lakes. (3) Temporally, lake-area variations exhibited distinct stage-wise characteristics. Lake-area declined from 1990 to 1995, with an average annual loss of 23.26 km2·a-1, followed by continuous expansion after 1995. Notably, this period accounted for a rapid increase of 52.56 km2·a-1. Between 2000 and 2005, the mean annual growth rate of lake-area was 39.90 km2·a-1. After 2005, the rate of extreme changes fluctuated slightly but maintained an overall increasing trend. (4) Lake expansion on the northern slope of Kunlun Mountains was primarily driven by glacier and snowmelt resulting from the combined effects of soaring temperatures and increased precipitation. Over the past 35 years, mountain water storage has increased markedly and was accompanied by increases of 35.30% and 13.18% in temperature and precipitation, respectively. The Cherchen River and Kumukuli Basin exhibited particularly strong responses to these climatic changes. Conversely, fluctuations in plain lakes were mainly governed by the synergistic effects of enhanced evaporative demand associated with rising temperatures and variability in precipitation. These findings provide important scientific evidence and policy-relevant implications for water resource management and climate impact assessment in the northern Kunlun Mountains region.
