梯川におけるネットワーク中心性分析を用いた景観・植物群落の遷移とその遷移に影響を与える物理環境特性に関する研究

抄録

This study analyzed successions of landscape and vegetation community in past 25 years using network centrality analysis in the Kakehashi river. Here, we aim to extract Landscapes Before Overgrowth of Wood lands (LBOWs) that have ability to indicate signs on over growth woodland. In the results, Phragmites japonica steud, miscanthus and water surface were extracted as LBOWs. It was estimated that succession from LBOWs to wood lands or to the other vegetation community was differentiated by flow direction, velocity change and sediment flux.
