Abstract

We analyzed the relationships between evapotranspiration and environmental factors using dataset of east Eurasian larch forest of eastern Siberia, northern Mongolia and Japan for the purpose of understanding the relationships between the forests and environmental changes.  We used the wavelet analysis across multiple timescales. We selected environmental factors, including soil water content, short-wave radiation, air temperature and water vapor deficit to analyze co-variability with the evapotranspiration. There was difference in the timescale in which co-variability is stronger than the other site. Siberian and Mongolian forest have stronger co-variability in the seasonal variation, while Japanese forest has stronger one in relatively short timescale. And the factors that have a great site-to-site difference in co-variability were soil water content and water vapor deficit. Both of them express the water condition at the forest. Therefore, the main reason of difference in site-to-site is water condition in the forest both of above and belowground.
