    Design and application of an intelligent framework for remote sensing interpretation of ecosystems

    • 摘要: 生态环境遥感监测作为国家生态治理与资源管理的重要支撑手段,正面临数据规模增长迅速、业务需求多样化与解译精度提升等多重挑战。为提升遥感解译的智能化水平,通过整合图像识别、智能解译、变化检测等算法模块,设计并实现了一套面向生态监测业务的遥感影像智能解译框架系统,可用于实现遥感影像从样本构建到多任务解译的全流程自动化处理。基于所提框架,以广东省试验区域为应用场景,开展了多时相影像变化图斑提取实证。结果显示,真动态图斑识别率达60.99%,面积覆盖率达78.94%,表明该系统在复杂生态背景下具备较强的变化识别能力与较高的智能解译效率,证实了其在实际业务中的适用性与稳定性。

       

      Abstract: As an important approach to supporting national ecosystem governance and resource management, remote sensing-based ecosystem monitoring is facing multiple challenges such as rapid growth of data volume, diversified business demands, and a demand for higher interpretation accuracy. To enhance the intelligence level of remote sensing interpretation, this study designed an intelligent framework of remote sensing image interpretation oriented to ecosystem monitoring services by integrating several algorithm modules, including image recognition, intelligent interpretation, and change detection. This framework enables automated processing of remote sensing images throughout the whole process from sample construction to multi-task interpretation. The proposed framework was verified by applying it to the extraction of patches with changes from multitemporal images of a pilot area in Guangdong Province. The results reveal that the recognition rate of patches with true changes reached 60.99%, with an area coverage rate of up to 78.94%. This finding suggests that the intelligent framework exhibits a strong capability of change recognition and a high efficiency of intelligent interpretation under complex ecological backgrounds, confirming its practicality and stability in actual applications.
