気候変動による森林流域の変化:長良川流域を対象として CLIMATE CHANGE INFLUENCE ON FOREST IN THE NAGARA RIVER BASIN
Access this Article
Annual changes in the temperature/precipitation and a runoff process in the forest watershed were investigated from the statistical analysis of various time series records. The climate change has not appeared in only a temperature increase but also changes in the precipitation pattern such as the extension of nonprecipitation period, the shortening of precipitation duration and the cyclic interval of heavy rain, and so on. Such climate change become causes of the shortening of precipitation-runoff response, the decrease of the amount of effective precipitation, and the increase of the sediment yields through the increase of evapotranspitation and the decrease of the soil moisture.
