摘要:

浮游生物是水生态系统的重要组成部分,其群落结构、丰度变化和优势种演替能够反映水体营养状态、生态扰动和环境质量变化,在水生态监测、有害藻华预警和水质评价中具有重要指示作用。传统人工镜检方法依赖专业经验,存在识别效率低、主观性强、连续监测能力不足等问题,难以满足水环境管理对实时化、精细化和自动化监测的需求。随着成像设备和图像识别算法的发展,浮游生物监测逐渐由人工取样和显微鉴定向自动化成像与智能识别转变。在此基础上,围绕图像获取、数据支撑、方法演进和场景应用等环节,系统梳理浮游生物图像采集设备、公开数据集及图像识别技术的发展现状,重点分析识别方法由人工特征提取和传统机器学习向深度学习发展的过程,以及相关技术在群落监测与生态响应分析、有害藻华预警和水质评价等领域的应用进展。同时,显微成像、流式成像和原位成像等设备为浮游生物图像获取提供了不同技术路径,其中原位成像更适用于真实水体连续监测;经过专家标注或人工校核的公开数据集可为模型训练与性能评价提供较可靠的数据基础。深度学习已成为浮游生物图像识别的重要技术路线,在提高识别精度和自动化水平方面表现突出,但仍面临数据集标准化不足、模型泛化能力有限、现场部署成本较高及多源信息融合不足等问题。未来,自监督学习、ViT和边缘智能等技术可在降低人工标注依赖、增强复杂图像特征表达和提升现场部署能力等方面发挥作用。推动原位成像监测、自动识别方法与水质参数分析相结合,有助于进一步提升浮游生物图像识别技术在水环境监测、预警和评价中的应用价值。

Abstract:

Plankton are essential components of aquatic ecosystems, and variations in their community structure, abundance, and dominant species succession can reflect changes in water trophic status, ecological disturbances, and environmental quality. Therefore, plankton serve as important bioindicators in aquatic ecological monitoring, harmful algal bloom early warning, and water quality assessment. Traditional microscopic identification methods rely heavily on expert experience and are characterized by low efficiency, strong subjectivity, and limited capability for continuous monitoring, making it difficult to meet the it difficult real-time, fine-scale, and automated aquatic environmental management. As imaging technologies and image recognition algorithms advance, plankton monitoring has gradually shifted from manual sampling and microscopic identification toward automated imaging and intelligent recognition. Based on this development trend, this review systematically summarized the current progress of plankton imaging devices, publicly available datasets, and image recognition technologies from the perspectives of image acquisition, data support, methodological evolution, and application scenarios. The transition of recognition approaches from handcrafted feature extraction and traditional machine learning to deep learning-based methods was analyzed, along with recent applications in community monitoring and ecological response analysis, harmful algal bloom prediction, and water quality assessment. Overall, microscopic imaging, flow imaging, and in situ imaging technologies were shown to provide diverse approaches for plankton image acquisition, with in situ imaging being better suited to continuous monitoring in natural aquatic environments. Public datasets established through expert annotation or manual verification were found to provide reliable data foundations for model training and performance evaluation. Deep learning has become a major technical approach to plankton image recognition, demonstrating significant advantages in improving recognition accuracy and automation capability. However, challenges remain, including insufficient dataset standardization, limited model generalization ability, high field-deployment costs, and inadequate integration of multi-source information. In the future, emerging technologies such as self-supervised learning, Vision Transformer (ViT), and edge intelligence are expected to reduce dependence on manual annotation, enhance feature representation for complex images, and improve field deployment capabilities. Integrating in situ imaging monitoring, automated recognition methods, and water quality parameter analysis will further enhance the application potential of plankton image recognition technologies in aquatic environmental monitoring, early warning, and assessment.
