不同林地清理方式对杉木萌芽更新的影响研究

在杉木林采伐迹地上进行不同林地清理方式对杉木萌芽更新影响的定位研究。结果表明：炼山清理迹地能提高萌条数量而且能促进萌条生长，提高萌条质量，并对伐桩的萌条分布也有一定影响，采伐时应尽量降低伐桩高度，并正确留条。

Effects of Different Forest Land Clearance Ways on the Spr out Regeneration of Cunninghamia lanceolata

The location study on the effects of different forest land clearance ways on the sprout regeneration of Cunninghamia lanoeolata has been conducted on the felling blanks of C. lanceolata forests and the results indicate that the felling blank clearance by burning the logging resid ues on a mountain can increase the number of coppice shoots ,promote their growth , improve their quality and also affect the distribution of the coppice shoots on stumps to a certain extent. The stump height should be reduced as fully as possible at the time of felling and the coppice shoots should be correctly left.
