Paleolimnology and Paleohydrology

摘要: The study of the sedimentary record nonmarine aquatic systems (paleolimnology) provides a tool for reconstructing history basins themselves, as well atmospheric and terrestrial that influence them. Such records allow us to understand environmental dynamics over periods longer than recorded history. Among inland systems, lakes have been studied more extensively; therefore, this review focuses on insights regarding structure function gained from studying lake sediments. Studies lacustrine paleolimnological used describe patterns long-term climatic variation response changes in climate catchment vegetation soils. Although ecological literature early decades twentieth century suggested became enriched time (eutrophic), eventually filling with sediment becoming wetlands, it is now clear there are multiple developmental pathways lakes. Some indeed become enriched, whereas others show decline nutrient concentrations pH. Similarly, succession bog or wetland not universal trend. Paleolimnological studies also reconstruct recent eutrophication, acidification, pollution. In these studies, archived sediments measuring magnitude human impacts environment evaluating whether fall outside natural range variation.
