Abstract

湧水湿地の研究が盛んである東海地方において,その認識史を整理し,ハビタットとしての湧水湿地の環境に関する理解の進展をまとめた.東海地方の湧水湿地は在地の本草学者らによって近世以前から知られていた.第二次大戦後,固有・準固有の種のハビタットとして改めて注目され,その環境の理解を目的とした研究が進んだ.現在,東海地方の湧水湿地の環境に関する研究は,分布及び成因,形成される場所の地形,面積,表層堆積物,水質,水文,存続期間と環境変化,生物的環境の各テーマについて,互いの関連性を考慮しながら進められている.得られた研究成果の中には,湧水湿地生態系の保全・管理に役立てられているものもあるが,まだ深い理解に到達していない部分は多く,さらなる研究が求められている.

Several seepage marshes are distributed across the Tokai area of Japan. Currently, they are in focus because theyrepresent some of the most critical habitats for various indigenous or endangered species. This paper presents the history of their recognition and summarizes the progress made in understanding their environment. The local botanists knew about the seepage marshes of the Tokai area even before the Meiji period. However, it was only after WWII, with the discovery of the unique flora of these marshes, that significant progress was made in elucidating the environment of these marshes. To date, many studies have focused on understanding the seepage marshes in the Tokai area and have explored a wide array of themes: distribution and cause, topography, surface sediments, water quality, hydrology, continuance, environmental changes, and the biological environment. Further, the inter-relationship between each of these themes have also been documented. Some of the key findings from these studies were applied to the conservation and management of the seepage marsh's ecosystem. However, with existing gaps in knowledge, further research is required to gain a deeper understanding of some of the understudied aspects of the seepage marshes.
