To the study about nature writing in Taiwan, I have believed that for the past several years there are some areas of this field waiting to be developed. The first need is to clarify the definitions of nature-oriented writing, nature writing, and environmental writing. The second is to use Taiwanese postwar novels and poetry as research subjects and continue to explore hidden "nature consciousness" or "environmental ethics" in these texts. The third is to investigate the meanings of writings which are about the specific environment and landscapes. Finally, the fourth is to discuss nature consciousness in the native Taiwanese Han language literature. This essay is a preliminary study regarding the third topic.In the past, wetlands are not really an independent topic in the study of natural science or literature, so that sometimes the descriptions concerning this kind of landscapes are included in "sea writing / literature" or "river writing / literature" in Taiwan. Especially when the texts about coasts are included in the former, we can find out that wetlands' ecological image is much more vivid and the environmental consciousness is much stronger in nature writing than in general literature. The preliminary discussion on the works regarding wetlands of Liu Ka-Shiang (劉克襄), Hung Su-Li (洪素麗) and Wu Yung-Hua (吳永華) has been made in this essay. For the future, I have a plan to connect the works concerning the experience of oceans and rivers all together to form a complete study on "the water consciousness" of Taiwanese literature.
