湖沙相映

2019-09-01 10:54來(lái)源：新華網(wǎng)

這是8月31日無(wú)人機拍攝的青土湖。

甘肅省民勤縣境內的青土湖是內陸河石羊河的尾閭湖，位于巴丹吉林沙漠和騰格里沙漠的夾縫地帶。上世紀初以來(lái)，因為上游來(lái)水減少，青土湖逐漸萎縮，1959年完全干涸，湖區形成了13公里的風(fēng)沙線(xiàn)。2007年石羊河流域重點(diǎn)治理工程開(kāi)始實(shí)施，通過(guò)上游節水、黃河調水等措施，民勤綠洲生態(tài)逐步改善，2010年青土湖重現碧波，水域面積不斷擴大。目前青土湖水域面積為26．7平方公里，湖區碧波蕩漾、蘆葦叢生，從空中鳥(niǎo)瞰，湖沙相映，蔚為壯觀(guān)。新華社記者聶建江攝
