摘 要 ：本文通过对福建三明连栽杉木林的根系进行了调查研究。结果表明：连栽林地上的根系重量、组成、形态和分布发生较大的差异，第一代杉木林地的单株根量分别比第二代、第三代高出24.93%、49.69%，全林分别为31.93%、55.22%；第一代的杉木林根系的组成和分布较合理，营养空间大，利于杉木的生长发育。

Abstract:The root system of the Chinese-fir stands on the repeated plantation woodland in Sanmin, Fujian was studied. The results showed that: the biomass, the constituent, the morphology, and the distribution of the root system of the Chinese-fir stands in replanting woodland vary significantly with the number of successive cultivation, The root biomass per tree in the first cultivation is 24.93% higher than that in the second, and 41.69% higher than that in the third. The sum of the root biomass of all stands in the first cultivation is 31.93% higher than that in the second, 55.52% higher than that in the third cultivation. The constituent, the morphology and distribution of root system in the first cultivation were more advantageous for the trees to enlarge their nutrient-absorption space and growth.
