Abstract: Based on the basic data of fishery statistics in Dongshan Bay in 2016,the key indicators of aquaculture area and structure were selected,and threshold parameters were given in this paper.The aquaculture area index,aquaculture structure index and aquaculture comprehensive index were calculated,and the evaluation index system of aquaculture carrying capacity was constructed.The carrying capacity of aquaculture in Dongshan Bay was evaluated by comprehensive evaluation of auxiliary and key indicators.The results showed that the area index(YS)of Dongshan Bay was 0.89,the structure index(YJ)was 0.02,and the comprehensive index(YZ)was 0.91.The carrying capacity of aquaculture in Dongshan Bay was critical overload by comprehensive evaluation method.Its overload characteristics were unreasonable distribution and too large scale of feeding culture in some sea areas.The main control measures were retreat in restricted areas,rational distribution and scale control of feeding culture.
