威尼斯式的“甜蜜生活” The Venetian 'dolce vita'

威尼斯潟湖中的三角洲, 意大利

今天图片中的是意大利威尼斯潟湖三角洲的壮观景色。该潟湖面积超过 212 平方英里,由屿、泥滩、运河沼泽组成,是整个地中海盆地最大的湿地之一。潟湖不仅是一个风景奇观,也是一个充满历史和创新的地方。它形成于上一个时期之后,在西元476年西罗马帝国灭亡前后,成为人们躲避入侵的避难所。在随后的几个世纪里,这些早期的定居者开始建造最终成为标志性城市的威尼斯。

如今,这片潟湖依旧是当地居民生活的重要组成部分,支撑着渔业、旅游业,甚至发展出可持续的水产养殖业。潟湖通过三个入口与亚得里亚海相连,并因“高水位”现象广为人知:即涨潮时水位升高,导致威尼斯部分街区被淹没。从古老的避难所到现代奇观,威威尼斯潟湖展现出人与自然共同塑造一片天地的典范。

A delta in the Venetian Lagoon, Italy

Pictured here is a spectacular view of a delta in the Venetian Lagoon, Italy. Spanning over 212 square miles, this lagoon is a rich mosaic of islands, mudflats, canals, and marshes, and it's one of the largest wetlands in the entire Mediterranean Basin. The lagoon isn't just a scenic wonder—it's a place steeped in history and innovation. Formed after the last Ice Age, it became a refuge for people fleeing invasions around the time of the fall of the Western Roman Empire in 476. In the centuries that followed, those early settlers began building what would eventually become the iconic city of Venice.

Today, the lagoon is still central to local life, supporting fishing, tourism, and even sustainable aquaculture. It's connected to the Adriatic Sea by three inlets and is famous for acqua alta, or 'high water,' when tides flood parts of Venice. From ancient refuge to modern marvel, the Venetian Lagoon is a reflection of how people and nature can shape a place together.

保护阿拉斯加的自然之美 Preserving Alaska's natural beauty

特里卡基拉河三角洲

1980年的这一天,历史上最大规模的保护地扩张使美国国家公园系统的规模扩大了一倍。在那之前,阿拉斯加没有国家公园,但现在该州有八个,加上众多的纪念碑和保护区,保护着超过1.57亿英亩的土地。当卡特总统签署《阿拉斯加国家利益土地保护法案》时,公众有权欣赏像今天照片中这样令人惊叹的地方:克拉克湖国家公园51英里长的特利卡基拉河的辫状河三角洲。

在当地的阿萨巴斯坎语中,Tlikakila字面意思是“鲑鱼在那里。”该公园以盛产鲑鱼的水道而闻名,因此,鱼类对当地经济和生态系统至关重要。当地的熊群从过量的鲑鱼中受益,在克拉克湖看熊很受欢迎。丰富的三文鱼也让公园里的狼群受益匪浅,这是世界上唯一一只只依赖三文鱼的狼群。

Tlikakila River Delta

On this day in 1980, the single largest expansion of protected lands in history doubled the size of the US National Park System. Prior to that day, Alaska had no national parks, but now the state has eight, plus numerous monuments and preserves that protect more than 157 million total acres. When President Carter signed the Alaska National Interest Lands Conservation Act, the public was granted the right to appreciate stunning locations like the one in today's photo: the braided river delta of the 51-mile long Tlikakila River in Lake Clark National Park.

In the native Athabaskan language, Tlikakila literally means 'salmon are there river.' The park is known for its salmon-laden waterways and, as such, the fish is of major importance to the local economy and ecosystem. Local bear populations benefit from the excess salmon, and bear watching is very popular at Lake Clark. The abundance of salmon has also benefited a wolf pack within the park—the only one in the world known to be solely dependent on salmon.
