説明

<p>Understanding hydrological partitioning and radiocesium depositional flux between the canopy and trunk compartments in the forested ecosystems affected by the Fukushima Dai-ichi Nuclear Power Plant accident are crucial in the estimating radiocesium inventory. Working in a coniferous forest and a mixed deciduous broadleaved forest, we investigated the precipitation partitioning via generation of branchflow and stemflow. Furthermore, we employed a dual isotope approach to determine the influence of water storage capacity in the alteration of the deposited radiocesium. Results revealed that branchflow and stemflow generation was greater in the canopy than in the trunk sections of the cedar stands, while in the oak stands the generation in the canopy shared nearly the same magnitude with the trunk. This led to a more significant contribution of leachable 137Cs in the canopy of cedar stands than in oak stands.</p>
