Abstract:Marine ecological disaster events are great destructive,and have a huge impact on social and economic development. It refers to the red tides, green tides or oil spill disaster, who may kill more than 10 people, or bring economic losses of more than 10 million RMB, or bring significant impact?to the coastal areas. Its disposal is along with each stage of the entire life cycle of the events. Reviewing disposal ability evaluation research, it was found that the existing research train of thought on how to construct the index system was single,?mainly based on life cycle of the events, on influencing factors of the events, based on one dimension of the "three-dimensional structure" ,?and the indicators is nonstandard and not comprehensive . Finally, these problems were tried to solve. From the elements dimension, process dimension and function dimension, the evaluation index system of Marine ecological disaster disposal ability based on three-dimensional structure was put forward , providing reference for follow-up study.
