Abstract
en
This study aims to clarify the causes of the expansion in alder forest in Kushiro Mire by analyzing the relationships among ground height, groundwater level and vegetation. In recent years, Kushiro Mire has been drying as a result of basin development, including river improvement, and the main vegetation has been rapidly shifting from reed communities to alder forest.Observation data analysis revealed that the area of alder forest is increasing at locations where the groundwater is -0.4 m or more underground. Groundwater simulation by analysis of observation data and unsteady two-dimensional model analysis indicates that groundwater levels are low at rivers and around former water channels. Because the groundwater level changes are large there, the area of alder swamp forest is expected to continue to expand.
