1984年以来，塔玛河林地有扩大的趋势。结果表明，河道植被演替与河床物质粒度、冲积层相对深度和地下水位等立地因子之间存在显著的相关性。河流植被的范围和类型主要是由洪水形成的细沉积物的场地因子决定的。研究结果表明，应用于冲积河流林地扩张或粗糙度的预测是有用的。
In recent years from 1984, the tendency of wood land expansion was observed in the Tama river. It becomes clear that there is significant correlation between the succession of instream vegetation and the site factors such as bed material grain sizes, relative depths of stored alluvium and groundwater levels on the gravel river-bed. The range and types of vegetation in rivers are determined by site factors of fine sediments that resulted from flood above all things. The result of this research shows usefulness of applications for forecasting wood land expansion or roughness in alluvial rivers.
