It is a habitual tactics to estimate the possibility of successfulness by applying similar ecological method on two different environmental conditions. The "similarity" between environments becomes a key indicator to identify the possibility of similar results. In general, the more the environmental conditions are similar, the effects were predicted more closely alike under the same circumstances.
This study is attempt to introduce fuzzy environmental similarity analysis as a prediction method, aiming shell-shaped CCA as target species, to explore the significance in quantifying the “distance” of environmental differentiation, and take it as base to realize the superiority of environment conditions in reef-building. Further, take it as a tool to predict the effectiveness of shell-shaped CCA ex-suit rehabilitation.
The research based on four existing sites, including Shi-Men, Chien-Shui-Wan, Shu-Lin-Zhi and Da-Tan which located in north-western part of Taiwan, in which shell-shaped CCA were found while in different growing conditions. Some key factors which affecting shell-shaped CCA growth, including water turbidity, water temperature, salinity and nutrients has been chosen as indicators, and the relative data were brought into the "CCA Fuzzy Evaluation Model" set to form an environmental fuzzy set. The similarity relationship between the four samples environments were quantified in “distance” with Hamming Similarity Set.
According to the examination results has indicated that the actual coverage rate of CCA at four sites is partial related to the degree of environmental similarity presented by fuzzy quantification. In addition, the experiences and the difficulties, as well as the prediction performances in conducting the environmental similarity analysis is illustrated in this thesis.
To apply the environmental similarity analysis in performance prediction of shell-shaped CCA ex-suit rehabilitation is an approach, and expected to be broaden the scope to other similar cases.
