Distribution and Utilization on the Resources of Buried Wood of Cunninghamia Unicanaliculata in China
【摘要】 杉木阴沉木系历史上因地震山崩倒埋的杉木形成 ;由于出土后木材比重比水大 ,沉于水 ,故称阴沉木 ;杉木阴沉木集中分布在我国长江中上游地区 ,川西南安宁河流域、川滇交界金沙江流域、湘黔交界沅水上游、湘桂交界湘水上游及鄂西南是资源较多的地区 ;阴沉木对研究杉木植物地理学、育种学、木材学、林产化工及地质与地震等有重要科学价值
【Abstract】 The buried wood of Cunninghamia unicanaliculata was formed by the buried Cunninghamia lanceolata as a result of earthquakes and landslides in history.Because its density was heavier than water,it was named as buried wood of Cunninghamia unicanaliculata.It is contral distributing in the upper and middle reaches of Changjiang River. Anning River Valley in the west-south of Siquan Pro., Jingsha River valley of the juncture of Siquan Pro.and Yunan Pro.,the upper reaches of Yuanjiang River valley in the juncture of Hunan Pro.and Guizhou Pro.,he upper reaches of Xiangjiang River in the Juncture of Hunan Pro. and Guangxi Pro.and the west-south of Hubei Pro. is also rich in its resources. The buried wood of Cunninghamia unicanaliculata is very important in science specially on the botany geography of Cunninghamia lanceolata,research of breeding,reseach of wood,research of forestry chemical industry,geology and earthquake.
