Abstract: 河道における過剰な植物の繁茂はその河川の治水上の弱点になることがあるが,一方,河川環境の一要素として重要でもある。したがって,適切に植生を管理する必要があるが,その際自然洪水が植生の流失にどの程度貢献するのかを明らかにする必要がある。本研究では,鳥取県千代川で2004年に発生した洪水前後の砂州上の植生の変化を写真解析と水理計算から検討する。また,従来の植生の遷移過程に関する従来の知見を使って植生の経年変化をシミュレーションし,伐採や人工洪水が植生分布に与える影響について検討する。
In many rivers, the sand bars have been hardly fixed and covered by vegetation. The vegetation is an obstacle for flood control. However, it is also an important factor creating a biological variety. Therefore, we need to keep the botanical situation much better from a point of flood mitigation and also from an ecological point of view. Firstly, we have investigated the change of vegetation caused by a heavy flood in the Sendai River. Secondly, we have predicted the vegetation disappearance by various scales of flood. These results are fundamental data for vegetation management for a preferable botanical situation. Finally, we have discussed the effect of artificial floods and vegetation cutting on the botanical situation.
