翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク PCDitch ： ウィキペディア英語版 PCDitch PCDitch is a dynamic aquatic ecosystem model used to study eutrophication effects in ditches. PCDitch models the nutrient fluxes in the water, the sediment and the vegetation, as well as the competition between different groups of vegetation. PCDitch is used both by scientists and water quality managers. ==Background== As a result of intensive agriculture in catchment areas, many polder ditches have turned from a clear water state with submerged plant dominance into a state where the water is completely covered with duckweed. Dominance of free-floating plants poses a threat to biodiversity by causing dark an anoxic conditions in the water column, and is generally associated with poor ecological quality. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PCDitch」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
