The changes of accumulated snow were analyzed using the Long-term Hydrologic Assessment Model Considering the Snow Process (LoHAS) and the applications of the SNOWPACK snow cover model, based on climate change prediction data that was subjected to bias correction and for which down-scaling of 1-km mesh sizes in dam basins was performed. It was estimated that the following will occur: a decrease in water equivalent of snowpack in dam basins, a shift in the end of thaw to earlier and significant reductions in the snow cover period. In addition, it was revealed that the future snow will become granular earlier than it does at present. It is necessary to continuously and quantitatively investigate the influence of future climate change on the local economy with respect to winter tourism.}, pages = {205--211}, title = {将来の気候変化が積雪の量的・質的変化に及ぼす影響に関する研究}, volume = {72}, year = {2016}, yomi = {タニグチ, ヨウコ and ナカツガワ, マコト and クドウ, ケイスケ} }
