如果CITES是大写无误,那么可能是“Convention on International Trade in Endangered Species”的简称（CITES['saiti:z]）,也就是“濒临绝种野生动植物国际贸易公约”.documumentation么,不用解释了,文件的意思.
给个Wikipedia的解释.“Convention on the International Trade in Endangered Species of Wild Flora and Fauna”：The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is an international agreement between Governments,drafted as a result of a resolution adopted in 1963 at a meeting of members of the World Conservation Union (IUCN).Its aim is to ensure that international trade in specimens of wild animals and plants does not threaten their survival and accords varying degrees of protection to more than 30,000 species of animals and plants.
