%X The root system of the Chinese-fir stands on the repeated plantationwoodland in Sanmin, Fujian was studied. The results showed that:the biomass, the constituent, the morphology, and the distribution of theroot system of the Chinese-fir stands in replanting woodland vary signi-ficantly with the number of successive cultivation. The root biomass pertree in the first cultivation is 24.93% higher than that in the second, and41.69% higher than that in the third. The sum of the root biomass of allstands in the first cultivation is 31.93% higher than that in the second,55.52% higher than that in the third cultivation. The constituent, themorphology and distribution of root system in the first cultivation weremore advantageous for the trees to enlarge their nutrient-absorption spaceand growth.
