美翻!潜入水底 千岛湖“水下森林”首次曝光

in dlive •  6 years ago 

杭州,是一座森林城市。

1652.49万亩森林面积里,淳安做出了巨大贡献:超76%的森林覆盖率,让千岛湖绿树环绕,成为“天然氧吧”。


可你知道吗?

982平方公里的千岛湖,湖底却有一座浩瀚的“水下森林”,要知道这座森林为何形成,你就要知道千岛湖的过去。


1959年因为建造新安江水电站,筑坝蓄水形成了如今的千岛湖,我们现在所看到的岛屿,其实都是昔日被淹前的山峰,曾经也是群山叠翠的壮观景象。

与西湖“水下森林”的后天栽种不同,千岛湖“水下森林”是天然形成的,潜入水底,只见水草随波逐舞、小鱼穿梭期间,美不胜收。

千岛湖常年保持I类水质,与“水下森林”的净化作用不无关系,一棵棵水草,就是一个个“净水器”。


因为千岛湖特别的深,平均可达30米,所以想近距离看“水下森林”还非常有难度,但是,被树草覆盖的岛屿常年绿意盎然,照样能让你大饱眼福!
