基于福寿林场杉木林不同土层(15、30、45、60 cm)土壤微量元素的实测数据,分析了不同龄组杉木林土壤微量元素储量的变化特征。结果表明:随着杉木林的生长发育,0~60 cm土壤的微量元素Cu、Fe、Zn、Mn、B的储量都表现出了幼龄林较高,中龄林降低,成熟林又升高的变化规律,变异系数Cu>Mn>B>Zn>Fe。在0~60 cm土层内,3个龄组杉木林微量元素Cu、Fe、Zn、Mn、B储量依次为127.46~246.22、118 315.88~131 166.29、659.79~748.74、2 301.11~3 686.83、38.14~40.16 kg·hm~(-2)。随着土层的加深,3个龄组杉木林Zn的储量在各土层都呈现出均匀分布的规律,而Cu和Fe主要分布在土层15~60 cm范围内,下层土壤中的储量比...

Storages of microelement in the soils with different depths （15,30,46,60 cm） in Cunninghamia lanceolata in Fushou Forest Farm of Hunan Province were analyzed to understand the variation character- istics of soil microelement in three age-group of C. lanceolata. The results showed that with the growth and development of C. lanceo/ata,the microelement contents of Cu,Fe,Zn,Mn and B in soil layers of 0--60 cm were high in the young stand, low in the middle-aged stand, and increased again in the mature stand. The order of variation coefficient was...
