摘要：Karls. (Karl's lake) in Denmark has been subjected to domestic and agriculturalwastewater discharges for many years. The composition of water plants has changed, andthe lake has been less clear. Two types of methods are used to describe this transformation.The first is a historical survey of activities in the watershed and the environmental regulationof the lake. The other type of method includes chemical and biological indicators amongwhich are phosphorous and pollen measured in a sediment core to infer past environmentalchanges. Since the 1960's the lake has developed from an oligotrophic to a eutrophic lake,and environmental management has not succeeded in sustaining the water visibility in thesummertime
