【 摘 要 】
In order to analyse the ship sewage discharge and pollution characteristics, and put forward the solutions of pollution preventing and control, it is necessary to establish the ship sewage pollutants discharging inventory. Based on the ship AIS data source, the data preparation processes of AIS data cleaning, thinning and screening are established, and the rapid establishing method of discharging inventory is proposed. The concept of ship activity degree is put forward for the first time to characterize the density and residence time of ships in a certain time period and water area. On the basis of the ship sewage production-And-discharge characteristics and the pollution production coefficient, the formula of pollutants discharging inventory based on ship activity is established. Compared with the traditional datum based on the ship entry and exit visa, the proposed calculating method takes full account of the ship's residence time, loading and unloading, mooring and other activities in a certain water area and time period, as well as the pollution discharged by any transit ships. The method has been applied to the downstream sections of the Yangtze River. The ship sewage pollutants discharging inventory is established for the first time, and the change of pollutants discharging intensity along the Yangtze River has been studied by the geo-information system. The method proposed in this paper can be used to provide scientific basis for ship traffic management-And-control in certain sections, setting up discharging control area, layout planning of the public receiving facilities for ship pollutants, and to prevent the pollution of local waters caused by the ship sewage.
