| 摘要: |
| 文章基于危化品风险源、涉海敏感目标和船舶交通密度3种影响因素综合评价溢油环境风险状况。首先从空间分布和数量特征的视角，提取宁波市海域环境风险影响因子，建立海域环境风险评价方法和指标体系，然后依托GIS空间信息平台实现对宁波近岸海域环境风险空间布局的综合评价。结果表明，宁波慈溪市西北部和镇海区潜在的溢油环境风险极高，对石油泄漏的敏感程度也相对较高，进而表明该区域应列为重点风险管控对象；北仑区和奉化区东南部沿海区域和象山港东部海域，其溢油环境风险为一般水平，说明该区域应列为一般风险管控对象，其潜在的溢油环境风险属于中等敏感程度；而象山县东部及东南部、宁海县南部区域，该海域的潜在环境风险极低，其对溢油敏感程度较低。评价结果可为宁波市海洋环境风险防控及应急响应措施、海域空间资源利用配置等提供科学依据和有效借鉴。 |

| Abstract: |
| The environmental risk of oil spill was comprehensively evaluated based on the risk source of hazardous chemicals, sea-related sensitive targets and ship traffic density. Firstly, from the perspective of spatial distribution and quantitative characteristics, the impact factors of marine environmental risk in Ningbo City were extracted, and the assessment methods and index system of marine environmental risk were established. Then the GIS spatial information platform was used to evaluate the spatial distribution of environmental risks in Ningbo coastal waters. The results show that Cixi City in northwest and Zhenhai potential environmental risk of oil spill is extremely high, to the sensitivity of oil spill is relatively high, that these areas as the key control object; Beilun and Fenghua area in southeast coastal area and Xiangshan island in the east China sea, its environmental risk is general risk, that these areas for general control object, the potential environmental risk belongs to the medium sensitivity; The east and southeast of Xiangshan County and the south of Ninghai County have very low potential environmental risk, and their sensitivity to oil spill is low. The evaluation results can provide a scientific basis and effective reference for Ningbo′s marine environmental risk prevention and control, emergency response measures, and the utilization and allocation of sea space resources. |
