Abstract: A news headline is the punch line of a news report，whose purpose is to quickly draw readers’ attention to the body text. On the Internet，it plays a much more important role in enticing website visitors than it is in traditional media news reports. Featuring CE translation of online news headlines from the perspective of Ecotranslatology，and combining specific cases of CE translation，this paper points out that translators should take different components of the translational ecoenvironment into account and focus on threedimensional transformations (i.e. linguistic，cultural and communicative) under the guidance of“multidimensional adaptation and adaptive selection” for a translation of the highest level of“holistic adaptation and selection”.

Key words: Ecotranslatology, network, news headline, threedimensional transformations
