在日本北海道高位泥沼池,调查了远东红皮云杉(Piceaglehnii)、库页冷杉(Abies sachalinensis)和日本桤木(Alnusjaponica)树干茎流液的化学性质和泥炭孔隙水的化学性质,包括了横切和纵切面孔隙水化学性质。沼泽森林树干基部茎流对泥炭孔隙水化学性质有明显的作用,而且树基部的泥炭孔隙水化学性质具有物种特异性。远东红皮云杉茎流液和泥炭孔隙水中盐分含量最高,日本桤木则最低;盐分从茎基部向树冠形成浓度梯度。树冠下泥炭孔隙水化学受化学过程控制,孔隙水充沛条件下,控制作用减弱,因地势平缓(<1°)茎流移动缓慢。事实上,泥炭孔隙水充足会使茎流化学物质浓度降低。微生物活动、优势树冠的营养再生介导的表面水和茎流对森林沼泽地微生境化学环境的空间异质性有贡献。图2表2参44。
Chemical properties of the stem sap liquefaction and peat pore water chemistry of Piceaglehnii, Abies sachalinensis and Alnusjaponica were investigated in high mud pools in Hokkaido, Japan, including horizontal Chemical properties of pore and water cut and slitted. The stem-stem flow in the swamp forest has a significant effect on the chemical properties of peat pore water, and the peat pore water chemistry at the base of the tree is species-specific. Far Eastern red spruce sap flow and peat pore water content of the highest salt, Japanese alder is the lowest; salt concentration from the base to the crown to form a concentration gradient. Under the canopy, peat’s pore water chemistry is controlled by the chemical process. Under the condition of abundant pore water, the control effect is weakened, and the flow of the stem flow is slow due to the gentle terrain (<1 °). In fact, a sufficient amount of peat pore water will reduce the concentration of stem flow chemicals. Microbial activities, surface water and stem flow mediated by vegetative regeneration of dominant tree canals contribute to the spatial heterogeneity of the microbial environment in the forest marshes.
