Abstract

IntroductionIn the future, China's mariculture must maintain its scale and improve quality. Crucial measures for achieving this goal are to optimize the layout of sea areas for aquaculture, strengthen the suitability assessment of marine aquaculture, and delineate suitable areas.MethodsThis study aims to scientifically identify marine aquaculture zones suitable for marine spatial planning by constructing a comprehensive suitability assessment system, incorporating both natural and social factors. The weights of the evaluation indicators were determined using the Analytic Hierarchy Process (AHP). Taking the Lianyungang sea area as a case study, GIS technology was employed to analyze marine aquaculture suitability based on the proposed index system.ResultsThe results categorized the Lianyungang sea area into aquaculture zones with varying suitability levels: excellent, good, average, poor, and very poor. Based on these findings, the study further classified the area into three types of management zones: key, moderate, and limited mariculture zones.DiscussionIn order to provide better decision support services and take into account the matching with Marine spatial planning and double evaluation, it is necessary to classify the evaluation results to facilitate users to propose scientific and practical management measures in this paper. Based on the evaluation results of mariculture suitability in the research area, it is necessary to strengthen the protection and development of mariculture suitable areas by providing sufficient resources and maximizing development potential.

基于GIS的海水养殖适宜性评价研究——以连云港海域为例

未来，中国的海水养殖必须保持规模，提高质量。优化养殖海域布局，加强海洋养殖适宜性评价，划定适宜区是实现这一目标的关键措施。方法通过构建综合考虑自然因素和社会因素的适宜性评价体系，科学确定适合海洋空间规划的水产养殖区。采用层次分析法（AHP）确定评价指标的权重。以连云港海域为例，基于所提出的指标体系，运用GIS技术对该海域的海水养殖适宜性进行了分析。结果将连云港海域划分为适宜性等级为优、良、一般、差、极差的养殖区。在此基础上，进一步将该区划分为重点、中等和有限海水养殖区三类管理区。为了提供更好的决策支持服务，同时兼顾与海洋空间规划的匹配和双重评价，本文有必要对评价结果进行分类，方便用户提出科学实用的管理措施。根据研究区海水养殖适宜性评价结果，有必要加强对海水养殖适宜区保护和开发，提供充足的资源，最大限度地发挥开发潜力。

期刊介绍： Frontiers in Marine Science publishes rigorously peer-reviewed research that advances our understanding of all aspects of the environment, biology, ecosystem functioning and human interactions with the oceans. Field Chief Editor Carlos M. Duarte at King Abdullah University of Science and Technology Thuwal is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, policy makers and the public worldwide. With the human population predicted to reach 9 billion people by 2050, it is clear that traditional land resources will not suffice to meet the demand for food or energy, required to support high-quality livelihoods. As a result, the oceans are emerging as a source of untapped assets, with new innovative industries, such as aquaculture, marine biotechnology, marine energy and deep-sea mining growing rapidly under a new era characterized by rapid growth of a blue, ocean-based economy. The sustainability of the blue economy is closely dependent on our knowledge about how to mitigate the impacts of the multiple pressures on the ocean ecosystem associated with the increased scale and diversification of industry operations in the ocean and global human pressures on the environment. Therefore, Frontiers in Marine Science particularly welcomes the communication of research outcomes addressing ocean-based solutions for the emerging challenges, including improved forecasting and observational capacities, understanding biodiversity and ecosystem problems, locally and globally, effective management strategies to maintain ocean health, and an improved capacity to sustainably derive resources from the oceans.
