To clarify the effect of coastal environment on quality of Phyllostachys edulis timber, comparison and analysis on physical and mechanical properties of bamboo timber from coastal windward side stand and inland stand was carried out. The results showed that the basic density, air-dry density, oven-dry density, compressive strength parallel to grain, bending strength, elastic modulus in bending of bamboo timber increased with bamboo age increasing on the whole. Effect of coastal windward environments on basic density, air-dry density, oven-dry density, compressive strength parallel to grain, bending strength and elastic modulus in bending of bamboo timber was not obvious, that on timber shrinkage was significant and bending strength of young bamboo (1 a and 3 a) increased remarkably. All results indicated that coastal windward environments was in favor of enhancement in mechanical properties and resistance to wind stress of Ph. edulis forest, and Ph. edulis can be used to construct eco-economic protective forests system at coastal region.
