這是11月14日在甘肅省酒泉市阿克塞縣阿伊納鄉拍攝的小蘇干湖風光（無人機照片）。入冬以來，位于甘肅省酒泉市阿克塞哈薩克族自治縣境內的“姊妹湖”——大、小蘇干湖陸續封凍。大、小蘇干湖由祁連山冰雪融水匯聚而成，雖一水相連，卻呈現“上游小蘇干湖為淡水湖、下游大蘇干湖為咸水湖”的獨特現象。它們共同在廣袤戈壁中滋養出一片生機盎然的生態濕地，成為我國候鳥遷徙路線上重要的中轉站和繁殖棲息地之一。[新華社記者 郎兵兵 攝]

An aerial drone photo taken on Nov. 14, 2025 shows a view of the Xiaosugan Lake in Kazak Autonomous County of Aksay, Jiuquan, northwest China's Gansu Province. Dasugan Lake and Xiaosugan Lake are connected and are both formed by the meltwater from the Qilian Mountains. A unique phenomenon is that the upstream Xiaosugan Lake is a freshwater lake, while the downstream Dasugan Lake is a saline lake. Together, they nurture a vibrant ecological wetland in the vast Gobi Desert, serving as an important stopover and breeding habitat for migratory birds along China's migration routes.
