摘要
本文根据2016年东山湾渔业统计基础资料,选取养殖面积、养殖结构等关键指标,赋予阈值参数,计算养殖面积指数、养殖结构指数和养殖综合指数,构建了东山湾养殖承载力评价指标体系。采用辅助指标和关键指标综合评价方法,对东山湾水产养殖承载力进行评价。结果表明:东山湾养殖面积指数(YS)为0.89,养殖结构指数(YJ)为0.02,养殖综合指数(YZ)为0.91。东山湾水产养殖承载水平为临界超载,超载特征为布局不合理、局部海域投饵型养殖规模过大,主要管控措施为限养区退养、合理布局、控制鱼类等投饵型养殖生物养殖规模。
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.
