三峡库区消落带土壤淹水的周期性常年变化，势必影响到土壤营养元素含量、土壤肥力、土壤理化性质等土壤特性的变化(Ponnamperuma，1972；李其林等，2004；杨刚，2004)，但土壤营养元素含量的影响是导致土壤其他特性发生相应变化的根本原因之一(金为民，2003；岳庆玲等，2007)。

Results show that the basic density, air-dry density, bending strength, modulus of elasticity, and compressive strength parallel to grain of T.'zhongshansha 302' are higher than those of T. distichum, and the oven-dry shrinkage and the air-dry shrinkage in tangential and volume are lower than those of Taxodium distichum, and the differences are all prominent at the 0.05 level.
