| Abstract: |
| The vegetation in North Guangdong was badly damaged by the unusually heavy snow and ice storms in early 2008. This paper investigated the way to restore and reconstruct the damaged Cunninghamia lanceolata plantations in Tianjinshan forest farm. In the sampling site all the C. lanceolata trees were cut in 2009, and six tree species of Magnoliaceae were planted in April 2010, while some bud bars of C. lanceolata were chosen to retain. The results showed that all the six species were suitable for the local habitat .The survival rate of each species was more than 80%. The seedlings of Michelia macclurei, M. wilsonii and Magnolia officinalis survived better and grew faster than the other three species (Manglietia yuyuanensis, Michelia maudiae and Tsoongiodendron odorum). The bud bars of C. lanceolata retained grew well and were dominant in the reconstructed forest stands. |
