丽江古城建筑物梁柱腐朽真菌鉴定

Identification of Fungi from Beams of Decay Building in Ancient Town of Lijiang

通过形态观察和分子生物学技术,对采集自丽江古城的建筑物梁柱上的木腐菌进行鉴定。结果显示,引起丽江建筑物梁柱褐色腐朽的真菌为绵腐卧孔菌(Postia placenta)。同时提出相应的防治建议,以期尽可能地降低丽江古城建筑物的安全隐患。

The bricky-timberwork buildings of Naxi have been the most common buildings in Lijiang city, Yunnan Province. These wooden structures play an important role in a long history culture of Lijiang. In view of the long history, we should pay more attention to the safety issues. A wood-decay fungus, collected from ancient building beam of Lijiang, was identified by molecular biology techniques. The final result showed that the fungi causing building brown rot was Postia placenta. At the same time, we also provided suggestions to reduce the potential safety problems of ancient buildings as much as possible.
