"In the language of the Mayan peoples who once inhabited this region, Sian Ka'an means 'Origin of the Sky'. Located on the east coast of the Yucatán peninsula, this biosphere reserve contains tropical forests, mangroves and marshes, as well as a large marine section intersected by a barrier reef. It provides a habitat for a remarkably rich flora and a fauna comprising more than 300 species of birds, as well as a large number of the region's characteristic terrestrial vertebrates, which cohabit in the diverse environment formed by its complex hydrological system."
"古代玛雅人曾在这个地区居住过，在他们的语言里，圣卡安是“天之源”的意思。这一生物保护区位于尤卡坦半岛东岸，内有热带 森林、红树林和沼泽地，还有被礁石分割开的海产区。这个自然保护区为大量的动物和植物提供了生活场所，其中包括300多种鸟类，以及大量当地特有的陆地脊 椎动物，这些动物在这个多样性的环境里共同生活，形成了一个复杂的水文学系统。"
