Comparison on the Wood Physical and Mechanical Properties between Liquidambar formosana Plantations and Natural Forests

The results show that the wood physical and mechanical performances of Liquidambar formosana natural forests are slightly superior to those of L.formosana plantations,whereas homogeneities of wood physical and mechanical properties of natural forests are slightly inferior to those of plantations;the difference significance t test reveals that except that the difference between the shearing strength of wood along the edge grain and cleavage resistance in the wood physical and mechanical property indexes of L.formosana plantations and natural forests is significant,the differences among other indexes aren't significant.
