普陀区海洋船舶的污染物主动纳污分层数据

随着船舶数量越来越多，船舶污染物主动纳污的管理难度加大，通过污染物回收频次和信用分算法，给船舶分配三色码（红、黄、绿）标签，并计算出所属辖区级绿码船舶的占比，便于相关部门对船舶主动纳污情况进行分析，加大对辖区黄码、红码船舶的主动纳污管控，利于环保。根据普陀地区配置， 健康码创建时间即为船舶录入系统的时间，此时船舶的初始码为绿码， 若在规定时间范围内，船舶入港至少1次且90天内未纳污，计扣分行为，赋黄码， 若船舶入港至少3次且180内未纳污，计扣分行为，赋红码， 若黄、红码在规定的时间内纳污，则赋绿码。 具体扣的分数，依照各区域内部规则而行，信用得分滚动更新。 数据算法：普陀区绿码船舶占比=绿码渔船数量/三色码渔船数量*100%。With the increasing number of ships, the management difficulty of active pollutant reception for ship-generated pollutants has risen. By leveraging the pollutant recovery frequency and credit score algorithm, ships are assigned three-color code (red, yellow, green) labels, and the proportion of green-code ships under their respective jurisdictions is calculated. This enables relevant departments to analyze the active pollutant reception status of ships, strengthen the supervision and control over yellow-code and red-code ships within the jurisdiction, and support environmental protection efforts. According to the configuration of Putuo District: The creation time of the three-color code corresponds to the time when the ship is registered in the system, and the initial code assigned to the ship is green code. If a ship enters the port at least once and has not received pollutants within 90 days within the specified timeframe, it will be categorized as a deduction behavior and assigned a yellow code. If a ship enters the port at least 3 times and has not received pollutants within 180 days, it will be categorized as a deduction behavior and assigned a red code. If a yellow-code or red-code ship receives pollutants within the specified timeframe, it will be reclassified as a green-code ship. The specific points deduction rules shall comply with the internal regulations of each region, and the credit score will be updated dynamically. Data Algorithm: Proportion of green-code fishing vessels in Putuo District = (Number of green-code fishing vessels / Total number of three-color code fishing vessels) × 100%.
