The sustainable development of aquaculture is a crucial determinant of food security, the well-being of aquaculture practitioners, and economic growth within coastal regions. Considering the existing gap in research regarding spatial and temporal development of aquaculture, this study investigates the progression of aquaculture practices over time and across various locations in Fuding City, China.
We retrospectively collected temporal and spatial data on aquaculture, as well as demographic, social, and economic data for Fuding City from 2010 to 2020. By employing 3D kernel density analysis, we illustrated the temporal and spatial changes in aquaculture. Furthermore, we utilized Ordinary Least Squares regression to investigate the driving factors behind the spatial changes in the aquaculture industry.
Over the past decades, we observed that in Fuding City, both the number of fishing rafts and aquaculture households initially decreased and then increased. The spatial distribution of aquaculture experienced a shift from the west (inner bay area) to the east (coastal area). Additionally, the type of fishing rafts also varied by region, with traditional rafts dominating the western inner bay and plastic rafts prevalent in the eastern offshore areas. Analysis of driving factors revealed that at least six factors have a significant positive correlation with the eastward shift of the aquaculture industry's center, including the proportion of migrant population, proportion of aquaculture to total fishery output, average temperature, investment in aquaculture technology, total fish sales, and GDP of Fuding City.
This study examines the spatial and temporal dynamics of aquaculture in Fuding City from 2010 to 2020, proposing an innovative approach to spatial optimization that integrates both horizontal and vertical strategies. These insights aim to guide the development of coastal aquaculture policies and support sustainable regional development, fostering a balanced coexistence between human activities and marine environments.
水产养殖业的可持续发展是粮食安全、水产养殖从业者福祉以及沿海地区经济增长的关键决定因素。鉴于目前在水产养殖时空发展研究方面存在差距，本研究调查了中国福鼎市水产养殖活动随时间推移以及在不同地点的发展情况。
我们回顾性收集了2010年至2020年福鼎市水产养殖的时空数据以及人口、社会和经济数据。通过采用三维核密度分析，我们展示了水产养殖的时空变化。此外，我们利用普通最小二乘法回归来研究水产养殖业空间变化背后的驱动因素。
在过去几十年里，我们观察到在福鼎市，渔排数量和水产养殖户数最初减少，然后增加。水产养殖的空间分布经历了从西部（内湾地区）向东部（沿海地区）的转移。此外，渔排类型也因地区而异，传统渔排在西部内湾占主导地位，塑料渔排在东部近海地区普遍存在。驱动因素分析表明，至少有六个因素与水产养殖业中心东移存在显著正相关，包括流动人口比例、水产养殖占渔业总产出的比例、平均温度、水产养殖技术投资、鱼类总销售额以及福鼎市的国内生产总值。
本研究考察了2010年至2020年福鼎市水产养殖的时空动态，提出了一种整合横向和纵向策略的空间优化创新方法。这些见解旨在指导沿海水产养殖政策的制定，支持区域可持续发展，促进人类活动与海洋环境的平衡共存。
