湖泊沉积物 Mg／Ca作为气候代用指标的局限性
Limitation of Mg/Ca Ratio as a Climate Indicator in Lake Sediment
摘要
Abstract
Mg/Ca as an indicator of paleoclimate and paleoenvironmental research has been widely used .Especially in paleo-ceanographic studies, this indicator has been an important tool for instruction of ancient sea water temperature .However, studies in lake sediments show that Mg/Ca is affected by many factors.Affected by the specific local environment of different regions, in-dicative meaning of Mg/Ca for the environment and climate changes are very different in lake sediment, and even contrary. This paper analyzes the relevance between Mg/Ca of sediments in Taihu Lake and regional environment change, compares with other studies results, and investigates the effect of different regional environment on the Mg/Ca of lake sediment.The results show that the Mg/Ca of the lake sediment has different environmental significance under the specific environmental impact.So the applica-tion of Mg/Ca as an indicator need to seriously study the particularity of the local environment and combine with other climate prox-ies in order to ensure the accuracy of the analysis of the environment and climate change.关键词
