碩士 / 東海大學 / 環境科學與工程學系 / 103 / There are many wetlands in Taiwan. Only in recent years, their value is becoming the concern of the people, and the governments enact legislations to protect the wetland. For bether management, it is desirable to know the relationship between the environment condition and the biological species. In this study, the largest black muddy wetlands in the Taiwan's Changhua wetlands is the study area. We collect the environmental and ecological species data, which are subjected to comprehensive statistical analysis by correlation, PCA, GIS. To employed examine the relationship between the environment and the ecology species by RDA. The result shows that most of benthic biological species have the positive correlation with the short-term’s pollution factors, and have the negative correlation with the long-term’s pollution factors. The prefered habitat for crab species, like Macrophthalmus banzai and Scopimera bitympana, is primarily defined by the sediment types. Moreover, the shellfish have the positive correlation with the heavy metal concentration because this is plausible that there species are toleranct to mild metal high toxicity. In the tidal creek’s identification, the Fu-xing Township and the Fang-yuan Township have the higher tidal creek density than other township.
