Abstract

本論では、沿岸干潟を対象に修復・創出手法の整理を試みる。干潟は、潮汐の干満につれ干出と水没を繰り返す比較的緩い勾配のまとまりある地形で、多様な生物生息が見られる浅海域に特徴的な地形である。干潟地形成立の様相から、潟湖干潟・河口干潟・前浜干潟に分類される。当面、空間スケールで高々数km程度の、生物の時間スケールで数年程度の、マクロベントスから飛来水鳥等も一部含まれる程度の生物群を対象に考えてゆく(1)干潟地形の修復による生息環境への手助けを行った事例の比較、および、(2)数十m2規模の干潟実験施設を用いてのメソコズム実験、の検討結果を整理してみた。

Associated with the port construction and/or coastal reclamation, it is sometimes required to construct newtidal flats or rehabilitate damaged tidal flats. Experiences on construction and rehabilitation along Japanese coastsare reviewed. Understanding of the physical systems which support benthic ecoIogical activities is necessary. Fiveelemental conditions can be pointed out for the supporting system. In the field, natural fluctuations of theseelemental conditions are inevitable. For the self-stability of the ecosystem, negative feedback mechanisms and/or environmental gradient and variety are important for designing and management in both constructions and rehabilitation of coastal tidal flats.
