项目摘要
A study was carried out at a boreal fores, eastern Canada. Conentrations of NH _4 ^+ and NO _3 ^- of precipitation in a forest are lower than that in a open area. The losses of NH _4 ^+ and NO _3 ^- are considered to be affected by the biological activity. Concentration of chemical substance of snowmelt water in a open area shows diurnal variation. The hydrograph of snowmelt is separated into "old water" and "new water". Meltwater in the lower snowpack is called to "old water", and meltwater percolated from surface snow layr is called to "new water". The separated "old water" is the major componentof early snowmelt runoff. "New water" is the major component of recession limb of the hydrograph.Seasonal change of surface impurities covering a perennial snow patch, Kuranosuke sekkei in Japan Alps, were analyzed. During the thawing period, amount and coloin darkness of the impurities gradually increased and bulk albedo of the snow patch was reduced in accordance with it. Microscopic observation and albedo spectrum of the impurities revealed that drkening of the impurity coloration was mainly due to the growth of cryo-microbes such as snow algae, fungi and bacteria growing in the melting snow.In some Himalayan glaciers, the microbial production on the glacier surface is so large during the monsoon that the surface of the ablation area is covered with a dark clored mud-like material which mainly consists of algae and bacteria. This material reduces the surface albedo of glacier and accelerates glacier melting.
一项研究是在加拿大东部的一个北部地区进行的。森林降水中NH_4~+和NO_3~-浓度低于开阔地。NH_4~+和NO_3~-的损失被认为是受生物活性的影响。开阔地带融雪水中化学物质浓度具有日变化特征。融雪过程线分为“老水”和“新水”。下部积雪中的融水被称为“老水”,从表面积雪中渗出的融水被称为“新水”。分离的“老水”是早期融雪径流的主要成分。分析了日本阿尔卑斯山库拉诺苏克积雪带表层杂质的季节变化。在解冻过程中,杂质的数量和黑度逐渐增加,雪斑的体积反照率相应降低。显微镜观察和杂质的反照率光谱表明,杂质变色的主要原因是雪藻、真菌和细菌等冷冻微生物在融化的雪中生长。在一些喜马拉雅冰川,季风期间冰川表面的微生物产量很大,以至于消融区表面覆盖着一层深色的泥状物质,主要由藻类和细菌组成。这种材料降低了冰川表面的反照率,加速了冰川融化。
