A Study on Measures to Prevent Water Eutrophication in Longhu Lake, Jinjiang

Abstract

As the biggest natural freshwater lake in Jinjiang, Longhu Lake now serves the drinking water source for four towns in South Shanxi Province and Jinmen. The paper evaluates the state of nutrition of Longhu Lake on the basis of analyzing the status quo of Longhu Lake, and proposes seven measures to prevent from reservoir eutrophication, including sewage interception and pipe layout, disposal of inbound rivers, vegetation buffer belt surrounding the lake, processing of endogenous pollution, construction of inbound wetland, biomanipulation and water quality monitoring. Through system engineering and non-engineering processing, enhancing control on pollution source and protecting ecological environment, we aim to protect the drinking water source.
