Eco-environmental Quality and Ecological Restoration: A Case Study in Wetland of the Loushan River Estuary, Jiaozhou Bay, Qingdao

The Coastal wetlands are important ecosystems between land and sea ecosystems. However, people develop wetlands so excess that decrease their areas and quantities. The coastal wetland has become a more frangibal ecosystem. Now the coastal wetlands of China are confronting serious threaten of wetland loss and eco-environmental deterioration. The research approach of the paper is an analysis of the data from collecting second-hand statistic information and data, according with from fieldwork. The results showed that the implementation of the scheme improved the hydrodynamic conditions of adjacent sea area. The flow velocity of this area has been greatly increased. Thus the self-purification capacity of this area has been enhanced. After building the sewage pipe network, The Pollutant Emission Amount was also reduced obviously. The exceeding standard area and the maximum concentration of the pollutant was considerably smaller. Status of serious pollution has been changed.
