摘要: 淺灘海岸之生物多樣性遠不如礁石海岸豐富,但仍有許多底棲、小型的節肢動物 及魚貝類棲息該地。淺灘水質環境及底質特性,影響淺灘生物自然演替的多樣性。谷 野(1997)在消波塊堆置所造成的空間,設計該區域中配合生物產卵模式之產卵礁技術工 法,藉以改善惡劣環境對幼卵的破壞,使之成為一個良好的增殖場,並可提供生態教 學的場所。由上述案例可瞭解海岸工程改善環境之技術,亦可使生態環境的多樣性獲 得可預期的改善並增進海洋生態之寓教於樂。又安平港之人工養灘計畫預計從2003年 九月開始至2004年七月完成。並根據該地過去將近一年之生態調查結果顯示,人造淺 灘環境中之二枚貝類為該區之指標生物。因此,本研究將於安平人工淺灘區佈放二枚 貝進行復育研究,以瞭解該海域進行水質及波流場的變化與貝類生物之關係,及生物 分佈與評估物理環境對生物的影響,並針對佈放區與人工養殖場之二枚貝類生長狀況 相互比較及評估。綜合上述影響二枚貝類生長情況之因素,本研究將建立海岸工程增 進淺灘區貝類復育之技術。
The biodiversity in the shallow sand beach is less than that in a reef. However, there are also many benthoses, small arthropod, fish and shellfish in shallow sand beach. Both water quality and subsoil affect the revolution of the bio-community. Yano (1997) proposed ecological blocks that are fit to fish spawn to improve the progeniture environment from the awful environmental change due to stacked armor units. This example reveals that the marine structures do some helps with the coastal ecology and provides with a good education function. A research base is located in the north beach beyond An-ping harbor breakwaters. Beach nourishment began in the September this year and will last until July next year. We have carried out two marine measurements on seawater and organisms in this year. According to the resulting organism recognition, we can choose bivalve that exists more than the other creatures to be the index organism for the beach. Therefore, this investigation is to breed the bivalve in an artificial shallow zone and to know the growth of the bivalve in site. From the instantaneous measurements on water quality and subsoil associated with numerical calculation on wave and current field, the effects of waves and current field on bivalve will be studied in the project. We also inspect the growth of the bivalve in site and compare with that in farm. The results of this project can provide the bivalve breeding in site in an artificial shallow zone.
