摘要: 对千烟洲试验区人工林的植物和土壤中15种营养元素的含量、分布和生物积累特征进行了研究。结果表明,两块人工林土壤中缺乏N、P、Ca3种元素,微量营养元素未发现亏缺现象。草本层的养分含量高于乔木层的养分含量。两块人工林的生物吸收系数均以P、Ca、N的吸收系数最大,Ti元素的生物吸收系数最低,其余的养分元素均属弱积累中等摄取的营养元素

关键词: 人工林, 营养元素, 生物积累

Abstract: Characteristics of concentration, distribution and bio accumulation of 15 nutrient elements in plants and soils of artificial forests in experimental plots of Qianyanzhou were studied. Results indicated that three elements of N, P,and Ca are deficient in soils of two artificial forest plots, but no inadequancies of trace nutrient elements are found. Nutrient content of grass layers is higher than that of tree layers. Biological absorption coefficients of P, Ca, and N are the highest for both plots of the artificial forests. Whereas bioabsorption coefficient of Ti is the lowest and the remaining nutrient elements belong to weak accumulation or moderate uplake type.

Key words: artificial forest, nutrient element, bio accumulation
