摘要：

To investigate the decay mechanisms of red oak (Quercus rubra) and hemor (Schima spp.) woods in the old architectural structure of Xichuan Guild Hall, chemical composition changes were determined and analyzed with X-ray photoelectron spectroscopy (XPS). The results showed that decaying resulted in a noticeable decrease of the O/C from 0.59 to 0.42 in the red oak wooden components. The increase of C-1 contribution, decrease of C-4 contribution, increase of O-1 and O-3 contributions, and decrease of O-2 contribution indicated that the carbohydrates in red oak wooden components can be easily degraded by fungi compared with lignin. Moreover, decaying resulted in a slight decrease of the O/C from 0.49 to 0.47 in the hemor wooden components. The results of increase of C-1 contribution, decrease of C-3 and C-4 contributions, increase of O-1, and decrease of O-2 and O-3 contributions indicated that carbohydrate and lignin were all degraded by fungi.
