摘要
在全球能源需求上升和环保意识增强背景下,光伏能源作为一种清洁可再生能源,备受世界各国关注。我国在光伏领域成绩斐然,不仅光伏装机容量和组件出货量位居世界首位,更是全球可再生能源发展的关键推动者。“渔光互补”模式创新性地将水产养殖与光伏发电相结合,有效提升了土地和水域的利用效率。然而,有关光伏板对海水养殖池塘环境及养殖生物的影响尚不明确。以三疣梭子蟹(Portunus trituberculatus)为研究对象,于2022年10月和12月在浙江舟山登步岛渔光互补基地,对比了覆盖光伏板与非覆盖光伏板梭子蟹养殖塘中水质、沉积物质量及梭子蟹生长及营养成分间差异。结果显示,调查期间光伏板对梭子蟹养殖塘水质参数(化学需氧量、亚硝酸盐、硝酸盐、无机氮、活性磷酸盐及总磷)有显著影响,但对水温和沉积物质量未发现显著差异。相关性分析显示,采样时间与养殖塘水温、活性磷酸盐和总磷呈显著负相关性(P<0.05),而与盐度、溶解氧、叶绿素a浓度呈显著正相关性(P<0.05)。在营养成分方面,梭子蟹的常规营养成分和脂肪酸与氨基酸组成主要受养殖时间变化影响,光伏板的存在对梭子蟹生长及其营养成分的影响有限。综上所述,“渔光互补”模式不会对梭子蟹养殖环境和产品质量构成威胁,研究结果为光伏板在海洋水产养殖业中的安全使用提供了坚实的理论依据,也为光伏渔业系统的进一步优化和可持续发展奠定了基础。
Against the backdrop of rising global energy demand and increasing environmental awareness,photovoltaic(PV)energy,as a clean and renewable energy source,has garnered significant attention from countries worldwide.China has achieved remarkable success in the PV sector,leading the world in both installed PV capacity and module shipments,and serving as a key driver of global renewable energy development.The“fishery-PV complementary”model innovatively integrates aquaculture with PV power generation,effectively enhancing the utilization efficiency of land and water resources.However,the impact of PV panels on the environment of seawater aquaculture ponds and the cultured organisms remains unclear.Therefore,this study focuses on the swimming crab(Portunus trituberculatus)as the research subject.In October and December 2022,at the fishery-PV complementary base on Dengbu Island in Zhoushan,differences in water quality,sediment quality,and the growth and nutritional composition of P.trituberculatus were compared between ponds covered with PV panels and those without.The results show that during the investigation period,PV panels had a significant impact on water quality parameters(chemical oxygen demand,nitrite,nitrate,inorganic nitrogen,reactive phosphate,and total phosphorus)in the P.trituberculatus ponds,but no significant differences were observed in water temperature and sediment quality.Correlation analysis revealed that sampling time was significantly negatively correlated with pond water temperature,reactive phosphate,and total phosphorus(P<0.05),while it was significantly positively correlated with salinity,dissolved oxygen,and chlorophyll-a concentration(P<0.05).In terms of nutritional composition,the conventional nutritional components,fatty acids,and amino acids of P.trituberculatus were primarily influenced by changes in cultivation time,with the presence of PV panels having limited effects on the growth and nutritional composition of the crabs.In conclusion,the“fishery-PV complementary”model does not pose a threat to the aquaculture environment orproduct quality of P.trituberculatus.This study provides a solid theoretical foundation for the safe application of PV panels in marine aquaculture and lays the groundwork for further optimization and sustainable development of PV fishery systems.
