The Great Barrier Reef is the world's largest coral reef system,composed of over 2,900 individual reefsand 900 islands stretching for 2,600 kilometres (1,600 mi) over an area of approximately 344,400 square kilometres (1.330105 sq mi).The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia.
The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms.This reef structure is composed of and built by billions of tiny organisms, known as coral polyps.The Great Barrier Reef supports a wide diversity of life, and was selected as a World Heritage Site in 1981.CNN has labelled it one of the seven natural wonders of the world. The Queensland National Trust has named it a state icon of Queensland.
A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as overfishing and tourism. Other environmental pressures to the reef and its ecosystem include water quality from runoff, climate change accompanied by mass coral bleaching, and cyclic outbreaks of the crown-of-thorns starfish.
大堡礁（英文：Great Barrier Reef），是世界最大最長的珊瑚礁群，位於南半球，它縱貫蜿蜒於澳洲的東海岸邊。全長共有2011公里，最寬處161公里。有2900個大小珊瑚礁島，自然景觀非常特殊。大堡礁的南端離海岸最遠有241公里，北端較靠近，最近處離海岸僅16公里。在落潮時，部分的珊瑚礁露出水面形成珊瑚島。在礁群與海岸之間是一條極方便的交通海路。風平浪靜時，游船在此間通過，船下聯綿不斷的多彩、多形的珊瑚景色，就成為吸引世界四方遊客來獵奇觀賞的最佳的海底奇觀。 1981年列入世界自然遺產名錄。
