The results show that, in terms of Decapoda fauna, there are 67 species in 20 families of Chinglou Wetland; include 13 species in 3 families of Macrura, 11 species in 4 families of Anomura, and 43 species in 13 families of Brachyura. Among these, Ocypodidae of Brachyura has the largest proportion with 12 species, while Amphidromous has 6 species in 4 families. In Caiyuan Wetland there are 49 species in 16 families; include 11 species in 3 families of Macrura, 6 species in 4 families of Anomura, and 32 species in 9 families of Brachyura. Among these, Portunidae of Brachyura has the largest proportion with 10 species, while Amphidromous has 6 species in 3 families. The two wetlands have a total of 22 families with 80 species for decapod crustacean, and 6 families with 9 species for amphidromous. In terms of distribution, Chinglou Wetland has the most species in coral fragments habitat type with 34 species in 10 families, and while Caiyuan Wetland has the most species in mangrove habitat type with 13 families and 31 species. For the distribution of indicator species, Chinglou Wetland has two species of Cardisoma carnifex in Gecarcinidae and Uca splendid in Ocypadidae, they are mainly distributed in the mangrove restoration area; Caiyuan Wetland has Helice formosensis in Grapsidae which is mainly distributed in the mangrove planting areas within fish ponds. This research also finds that both Chinglou and Caiyuan Wetlands have many coastal projects that can impact the habitat and the ecological path between the land and sea ecosystems. Therefore, this report also provides recommendation in hopes of making the wetland of Penghu and the related ecosystem further improved.
