【Abstract】 Investigation and analysis on characteristics of windthrows and gap damaged by two typhoons in 2005 in evergreen broad-leaf forest at Tiantong National Forest Park demonstrated that Castanopsis fargesii and Schima superba took the most part of the 111 windthrows belonging to 19 species, and uprooting occupied the most part of them by the path and gully in the park. Most windthrows had D.B.H of 10-30cm, and height of 10-20m. Small gaps were dominant after disturbance among the 10 gaps in the forest, the larger ones concentrated by the gully.更多还原
