The change of organic pollution in time is that the process of organic pollution is aggravating before July and reaches the serious pollution level in the entire Dongliu district in July. After July, the pollution degree gradually reduces. By September, the entire eastward flow District water quality restored to a better level. The spatial variation of organic pollution is gradually aggravating from the Gulf to the Gulf. The entire east stream reached eutrophication level in June, July and August, but the degree of eutrophication was different. The degree of eutrophication was the most serious in July, reduced in August compared with July and basically returned to normal in September . Compared with August 1994, organic pollution and eutrophication in the Dongliu District increased in August 1995.
