Description
Summary:To study the influence of human activity on natural lake, chironomid fauna change in the 700-560cm lake sediment in Quidenham Mere of England associated with chironomid inferred TP presented that the lake experienced a whole eutrophication process due to human hemp-retting in Post-Medieval based on the history record and pollen analysis, which was confirmed by mollusc and ostracod analysis. However, the response of chironomid and mollusc to retting was the strongest with ostracod a little behind. It proved that cultural eutrophication existed in history and could be recovered by itself despite of some long-term unachievahle destroy. And it was most important for external nutrient to be cut off during lake restoration even in ancient times.
