摘要
Ecological semiotics belongs to the field of culture,and biological semiotics refers to biology.There are both similarities and differences between ecological semiotics(ecosemiotics)and biological semiotics(biosemiotics)."Co-existence and co-prosperity"are the highest true meaning of human beings and nature.Faced with the increasingly serious ecological crisis,human beings,as the only semiotic animal that can reflect on sign activities,are ultimately responsible for other species and the entire ecological community.
