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.
