Spatial Variability of Throughfall in a Larch (Larix gmelinii) Forest in Great Kingan Mountain, Northeastern China

Larix gmelinii forest is one of the dominant types in boreal and plays a unique eco-hydrological role terrestrial ecosystem. However, throughfall variability ecosystems, which crucial regulating hydrology, remains unclear. Here, we investigated spatial temporal stability within full leaf stage Great Kingan Mountain, Northeast China, effects rainfall properties canopy structure on were systematically evaluated. The results indicate that represented 81.26% gross forest. CV (coefficient variation throughfall) had significant negative correlation with amount, intensity, duration, distance from nearest trunk, whereas it increased increasing thickness LAI (leaf area index). analysis suggested was mainly affected by amount (R2 = 0.7714) 0.7087). indicated distribution temporally stable. Our findings will facilitate better understanding spatiotemporal heterogeneity help accurate assessment soil water forests.
