摘要:
通过对九寨沟箭竹海沉积物样品中生物硅(BSi)含量的分析,讨论箭竹海沉积物中BSi含量与总有机碳(TOC)及粒度的关系,进而探讨BSi含量反映自然和人类因素对湖泊水体和沉积物的影响。箭竹海沉积物中BSi含量介于5.5～15.8 mg/g之间,BSi含量与TOC呈显著正相关关系。BSi含量还较显著地受到粒度影响,较细颗粒沉积物对BSi有较强的吸附作用。箭竹海沉积物中BSi含量变化与气温波动关系不密切,主要反映了森林砍伐和旅游开发等人类活动对湖泊水体和沉积物的影响。
Abstract:
The Biogenic silica (BSi) contents were determined in the sediments from Arrow Bamboo Lake in Jiuzhaigou National Reserve. Furthermore, the relationship between sediment total organic carbon (TOC) content, grainsize fraction and BSi content were discussed in order to trace the anthropogenic and/or natural effect on water quality and lacustrine sedimentation. The content of BSi ranged between 5.5 and 15.8 mg/g, and the BSi content in the sediments had a significantly positive correlation with TOC. Also, the BSi content was mainly controlled by the grainsize distribution in the core sediments, and the stronger adsorption to BSi occurred in the finer grain fraction. The variation of BSi values from the sediments in Arrow Bamboo Lake, insignificantly coupling with the air temperature, indicated the vital effects of deforestation and tourism on lake water and sediments.
