摘　　要：当前,基于卫星遥感的蓝藻水华自动化监测方法在应用中存在一定局限性,难以满足生态环境监管部门对业务化监测的需求。而最准确的蓝藻水华遥感监测方法仍依赖于有经验专家的目视解译,但缺乏经验的人员在解译过程中可能产生随机误差,难以支撑高精度的业务化应用。针对这些问题,讨论了基于目视解译的蓝藻水华提取影响因素,并构建了基于目视解译的蓝藻水华提取技术流程。该技术流程包括影像预处理、蓝藻水华提取和结果输出等环节,以实现高精度、规范化的蓝藻水华提取,且适用于多种多光谱卫星遥感数据。在此基础上,开发了基于目视解译的蓝藻水华提取辅助软件。该软件具备用户图形界面,支持多种卫星遥感影像数据,并提供多种格式的结果输出,可提高蓝藻水华目视解译效率,为基于卫星遥感的蓝藻水华业务化监测提供技术支撑。While satellite-based automated methods for Cyanobacterial algal blooms(CyanoABs)detection face operational limitations in meeting ecological monitoring requirements.At present,the most accurate remote sensing monitoring method for CyanoABs is visual interpretation by experienced experts,but inexperienced personnel may generate random errors in interpretation,making it difficult to support high-precision operational applications.To address these challenges,this paper examines the factors influencing the extraction of CyanoABs through visual interpretation and develops a technical workflow.The proposed workflow comprises image preprocessing,CyanoABs extraction,and result export,aiming to achieve high-precision and standardized extraction of CyanoABs.It is applicable to various types of multispectral satelliteremote sensing data.Building on this workflow,this paper develops a visual interpretation-based assistant software for CyanoABs extraction.The software features a user-friendly graphical interface and supports the extraction of CyanoABs from various remote sensing satellite images.It enhances the efficiency of visual interpretation for CyanoABs and offers technical support for operational monitoring based on satellite remote sensing.
