Yellowstone National Park is an American national park located in Wyoming, Montana, and Idaho. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world, established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular features. It has many types of ecosystems, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.
美国黄石国家公园座落在怀俄明州，蒙大拿州和爱达荷州。它是美国也是全世界第一个国家公园，1872年3月1 日由美国国会创办，且由尤利西斯·格兰特总统纪录入法典。公园闻名于它丰富的野生动物种类和地热特征，尤其是 “老而忠实的间歇泉”－一个最受欢迎的景点。它拥有多种生态系统，亚高山森林是最为丰富的一种。它也是南中部落基山脉森林生态区的一个组成部分。
Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world’s geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth’s northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.
黄石国家公园跨越 3,468.4 平方英里面积 (8,983 km2)，包含了湖泊，峡谷，河流和山川。黄石河是北美最高海拔的河流之一，以黄石火山口为中心－地球上最大的超级火山口，且是活火山，在过去200万年间曾多次爆发，制造了巨大的推动力。世界上超过一半的间歇泉和地热水都位于黄石公园内，由持续的火山运动推动。火山爆发形成的熔岩流和岩石覆盖了黄石公园绝大多数的面积。这个公园是大黄石生态系统的中心部位，它是地球北温带最大的留下的近乎完整的生态系统。黄石公园在1978年被评为联合国教科文组织世界遗产。
Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
