Assessment of Spatial Distribution and Source Apportionment of Land-based Pollutant Loads Generated in Qingdao, China
1.Research Background Since the late 1960s,with the continuous rapid development of society and the economy,the total terrestrial discharge amount in Qingdao has been increasing,resulting in deteriorating of water quality,especially in Jiaozhou Bay (JZB) (Wang et al.,2006).In order to improve the water quality,Qingdao municipal government issued the program of controlling terrestrial discharge of chemical oxygen demand (COD) and nitrogen in 2006 and 2011,respectively.However,based on the data from the Annual Bulletin of Qingdao Marine Environmental Quality,obvious reduction of polluted area in JZB was not seen,which implied that a significant improvement of water quality was not observed accordingly.The main reasons behind the inconsistence of pollutant discharge reduction and water quality deterioration may be that the current total amount control management failed to connect the amount of pollutant source with the target of receiving water quality (Wang,2013).
