摘要:
 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上层土壤储量明显要高,表现出明显的沉积现象,土层45~60 cm微量元素Cu和Fe的储量分别是土层0~15 cm的1.96~2.63倍和1.21~1.35倍。而Mn和B的储量随着土层的加深没有明显的变化规律。
Abstract:
 Storages of microelement in the soils with different depths(15,30,45,60 cm)in Cunninghamia lanceolata in Fushou Forest Farm of Hunan Province were analyzed to understand the variation characteristics of soil microelement in three age-group of C.lanceolata.The results showed that with the growth and development of C.lanceolata,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 Cu > Mn >B >Zn > Fe.The microelement storages of Cu,Fe,Zn,Mn and B were 127.46-246.22,118 315.88-131 166.29,659.79-748.74,2 301.11-3 686.83 and 38.14-40.16 kg·hm-2,respectively.With the increase of soil depth,the storage of Zn was evenly distributed in each soil layer,however,the Cu and Fe mainly distributed in the soil layer of 15-60 cm,their storages in the subsoil were higher than upper layer,which displayed an apparent deposition.The storages of Cu and Fe in the soil layers of 45-60 cm were 1.96-2.63 and 1.21-1.35 times higher than those in soil layer of 0-15 cm,but the storage of Mn and B had no significant changes with soil depth.
