岱山县海洋船舶的污染物主动纳污分层数据
收藏资源简介：
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。根据岱山县地区配置， 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：岱山县绿码船舶占比=绿码渔船数量/三色码渔船数量*100%。
With the continuous growth of the global shipping fleet, the management of ships' active pollutant reception has become increasingly challenging. By leveraging the pollutant recovery frequency and credit scoring algorithm, ships are assigned tags with three-color codes (red, yellow, green), and the proportion of green-code ships under their respective jurisdictions is calculated. This enables relevant authorities to analyze the active pollutant reception status of ships, strengthen the supervision and control of yellow-code and red-code ships in the jurisdiction, and support environmental protection efforts. Based on the configuration of Daishan County: 1. The creation time of a ship's health code refers to the moment when the ship is registered into the system, and the initial code assigned to the ship is green code. 2. If a ship enters a port at least once and fails to conduct pollutant reception within 90 days within the specified time frame, it will be deemed a deduction behavior and assigned a yellow code. 3. If a ship enters a port at least 3 times and fails to conduct pollutant reception within 180 days, it will be deemed a deduction behavior and assigned a red code. 4. If a yellow-code or red-code ship conducts pollutant reception within the specified time frame, it will be re-assigned a green code. 5. The specific points deduction rules shall follow the internal regulations of each region, and the credit score will be updated on a rolling basis. 6. Data algorithm: The proportion of green-code ships in Daishan County = (Number of green-code fishing vessels / Total number of three-color code fishing vessels) × 100%.
