摘要

研究了希腊两种森林类型(马基森林和山地冷杉森林)中硼(B)的状态和循环。在水循环过程中,两种林型的大体积沉积物中B的浓度都显著低于透雨中B的浓度,这意味着干沉积。结果还表明,B在两种森林上空的大气中都发生了一些远距离转移。马丘斯基林土壤中总B含量较高,反映了母质的化学成分,但也反映了马丘斯基林靠近海洋。同样地,猕猴桃林中黑栎叶中的B浓度高于冷杉针叶中的B浓度。这些因素影响了土壤溶液中的B浓度、水循环通量和两种森林的凋落物。在土壤中,速效B与两种森林的有机碳和碳氮比呈显著相关,但与总B不显著相关。在马奎斯样地,B在森林地面的停留时间较短,说明循环速度较快。山杉地的低温是造成这一现象的原因之一。

Cycling and status of boron in two forest types in Greece
The status and cycling of boron (B) were examined in two forest types in Greece, a maquis and a mountainous fir forest. In the hydrological cycle, in both forest types, the B concentration in the bulk deposition was significantly lower than that in throughfall implying dry deposition. It was also shown that some long-range transfer of B took place in the atmosphere above both forests. The total B in soils was higher in the maquis forest reflecting the chemical composition of the parent material but also the proximity of the maquis forest to the sea. Likewise, the B concentration in the holm oak leaves in the maquis forest was higher than that in the fir needles. These facts affected the B concentrations in the soil solution and fluxes in the hydrological cycle and litterfall of both forests. In soils, the available B correlated significantly with the organic carbon and the ratio of C/N in both forests but not with the total B. The residence time of B in the forest floor was lower in the maquis plot, which means faster cycling. The low temperatures in the mountain fir plot contributed to this fact.
