摘要:
产卵场保护区建立是养护渔业资源和渔业可持续发展的重要方式,为验证大陈洋产卵场保护区建立的效果,以大陈洋产卵场保护区为研究区域,基于层次分析法(analytic hierarchy process),以2018年春(4月)、秋(11月)两季渔业资源和环境调查数据为依据,从产卵场保护区的环境和生态(一级指标)角度考虑,建立以污染物、水质、群落结构、资源密度等7个二级指标和26个三级指标的评价体系,通过综合健康评价指数(comprehensive health indicator,Ic,h),表征大陈洋产卵场保护区健康状况,并利用2021年春(4月)、秋(11月)两季渔业资源调查数据与保护区建立初期渔业资源情况进行对比。结果显示:2018年大陈洋产卵场保护区春季和秋季Ic,h分别为0.514和0.511,均处于亚健康状态。虽然保护区内环境状况优良,但保护区内生物多样性低,资源密度和资源补充群体数量不足,这表明大陈洋产卵场保护区渔业资源情况不容乐观。经过一段时间的恢复,保护区内渔业资源情况略有所好转,说明保护区的设立有一定的效果。综合健康评价体系在一定程度上客观地反映了大陈洋产卵场保护区健康状况,研究结果可为保护区建立效果评价提供基础数据,也对大陈洋地区的渔业可持续发展具有重要意义。

Abstract:
Establishment of spawning ground reserve is important to protect fishery resources and the sustainable development. Dachenyang spawning ground reserve was established in 2017 and selected as the research area for study based on the analytic hierarchy process. The data source were from surveys in 2018 on environmental and fishery resource in spring (April) and autumn (November). From the environmental and ecological (first-level indexes) perspectives, an assessment system was established with 7 second-level indexes including pollutants, water quality, community structure, and resource density etc., and 26 third-level indexes. Recent data in spring (April) and autumn (November) of 2021 were used to compare the fishery resources before and after the establishment of the reserve. A comprehensive health indicator was used to assess the health status of the reserve. Results show that the comprehensive health indicator was 0.514 in spring and 0.511 in autumn, both were in sub-health status. Although the environment of the reserve was good, yet the resource density and biodiversity remain low, and the number of resource supplement groups was insufficient. Therefore, the situation of fishery resources is not optimistic. After a period of time of conservation, the situation of fishery resources has been improved, indicating that the reserve is effective. The health status assessment system could objectively reflect the health status of Dachenyang spawning ground reserve. This study provided basic data for the effective assessment of the reserve establishment, and shall help realize sustainable development of fishery resources in this and similar cases.
Key words:  spawning ground reserve  health status assessment  overexploitation  fishery resources
