| 摘要: | 圍潭溼地面積不大，屬於沿海濕地類型。溼地位於朴子溪下游接進出海口處，嘉義縣東石鄉蔦松村，朴子、東石、六腳三鄉市交界 。圍潭溼地研究範圍總面積二十一公頃。 圍潭溼地於民國九十四年七月一日至民國九十五年八月三十一日做環境生態棲地復育工作。本研究分別對圍潭溼地內之現地生物做生態資料調查。本研究分兩階段調查，總時程為一年。整地施工前之調查: 調查時程為六個月，其中兩個月為冬候鳥季。各項工程完工後之調查: 工程完工半年後開始調查，調查時程為六個月，其中兩個月為冬候鳥季。此工程包含堤防綠化美化、濕地整建、蚵殼賞鳥步道的建置。透過這次工程改變溼地內部水道，讓水流流經更多地區，擴展濕地面積，增加底棲生物。吸引候鳥來此棲息，以期恢復以往的盛況。而蚵殼步道建置，讓民眾更容易親近觀察溼地生態。 根據本研究的調查結果，植物種類共30科89種 ，溼地內以茳茳鹹草、巴拉草、蘆葦、象草、空心菜為主要植物。發現鳥種共18科41種，冬季時冬候鳥群聚來此過冬，但因圍潭濕地復育工程進行，來此過冬的候鳥跟以往幾千隻的盛況，無法比擬，明顯減少很多。圍潭濕地的水源來自朴子溪，其魚的種類與朴子溪息息相關，本研究調查到的有八種魚類。本區的招潮蟹根據調查共有八種，溼地內泥灘地上到處可見彈塗魚及招潮蟹出沒，可見本區生態資源異常豐富，是個很有潛力的溼地棲息環境。
The Weitan Wetland area, which belongs to the kind of coastal wetlands, is not large.Weitan Wetland, on the boundary of Puzi, Dongshin and Lioujiao, is situated in the downstream of Puzi Stream near estuary. The research area, around 21 square ha, covers the waterway outside the dry farmland. The authority had conducted the rehabilitation of the environmental ecology from July 1, 2005 to August 31, 2006. This research holds an ecology investigation which includes plants, birds, fish, and crustaceans. The research divided into two steps and last for one year. The first step takes six months, which include birds’ two-month migratory season, before the construction work . The second step also takes six months, which include birds’ two-month migratory season, after the construction work. The construction work includes greening on embankments, the reconstruction of the wetland, and the construction of the bird-watching path made of shells. With the new construction, the water courses in Weitan Wetland has changed. Waters flow into more areas. The wetland area is expanded; underwater creatures increase. It attracts migratory birds to inhabit. With the construction of the shell path, people are brought to the ecological environment of the wetland. According to the study’s result, we find eighty-nine kinds of plants which belong to thirty families separately. The main plants in the wetland are Cyperus malaccensis, Brachiaria mutica, Phragmites communis, Pennisetum purpureum, and Ipomoea aquatica Forsk. We also find forty-one bird species which belong to eighteen families separately. During the winter season, winter migratory birds gather here to pass the winter. However, the proceeding of the construction work makes the migratory birds reducing. Weitan Wetland’s water resource comes from Puzi Stream There are eight kinds of fishes and eight kinds of Uca arcuata in Weitan Wetland. We can also see Periophthalmus cantonensis and Uca arcuata on the mud here. Obviously, the ecological resources in this area is rich and it’s also a potential habitat for the creatures in the wetland. |
