东山湾渔业资源承载力评价指标体系构建及评估

Constructing and evaluating an assessment indices system for fishery resources carrying capacity in Dongshan bay

本文在《资源环境承载能力监测预警技术方法(试行)》的基础上,结合渔业资源的特有属性和东山湾的实际情况,探讨并优化完善了东山湾渔业资源承载力评价技术指标体系和方法。根据2016年春季(4月)和秋季(11月)东山湾游泳动物和鱼卵、仔稚鱼调查资料,结合2012~2013年的调查数据进行综合评估,结果表明东山湾渔业资源承载状况已临界超载。针对目前东山湾渔业资源承载现状,提出了进一步加强渔业资源监测调查、生态环境保护和监督管理等预警措施,旨为东山湾渔业资源可持续利用提供理论依据,为进一步推进海洋资源承载力评估业务化和其他海湾的渔业资源承载力评价提供借鉴和技术支持。

Based on the trial guidelines（ 2016 edition） to construct a monitoring and forecasting technology and method for resources and environment carrying capacity,combining the distinctive attribute of fishery resources and the practical situation of Dongshan bay,an assessment indices system and method for fishery resources carrying capacity in Dongshan bay has been modified. Based on the investigation on nekton,fish eggs,fish larvae and juveniles in the spring（ April） and autumn（ November） of 2016,combining the investigation data from 2012 to 2013 to make comprehensive assessments. The result showed that the fishery resources carrying situation in Dongshan bay has been critical. Therefore,we proposed forewarning measures,such as further strengthen monitoring survey of fisheries resources,ecological environmental protection and supervision and management,in order to provide the theory basis for sustainable utilization of fishery resources in Dongshan bay,furthermore,to provide reference and technical support for further promoting the operational marine resources bearing capacity assessment and fishery resources carrying capacity evaluation of other bays.
