【地下16米：延安如何打造城市绿洲？】90多年前，延安见证了中央红军二万五千里长征的胜利；90多年后，在陕北黄土高原的沟壑间，这片红色老区正积极探索着绿色发展的新路径。天然缺水的延安，人均水资源占有量不到全国平均水平的三分之一，如何让每一滴水“物尽其用”？全年干旱少雨，如何破解水体富营养化难题，为市民营造生机盎然的城市绿洲？今天的延安，正以实际行动回应这些现实课题。而延安人想出的新法子，竟藏在一座生态公园的地下16米深处。跟随CGTN主持人 @王冠Guan，一起来看！#长征胜利90周年# #长征路上看今朝# With its per capita water resources less than a third of the national average, how can the city of Yan'an, high on China's northwest Loess Plateau and suffering by long, dry spells and limited rainfall, make every drop count? How can it create thriving urban green spaces for its citizens? Despite the challenges, over 90 years after it witnessed the victory of the Central Red Army's Long March, Yan'an is forging a greener future. One key to this transformation lies 16 meters underground, beneath an ecological park in the city. Join CGTN host Wang Guan to find out how a miracle took shape!
