本报讯 近日，黑龙江省自然资源权益调查监测院（黑龙江省自然资源卫星应用技术中心，以下简称"黑龙江省卫星中心"）与黑龙江省 塔河县人民政府，联合自然资源部国土卫星遥感应用中心、国家卫星海洋应用中心，在大兴安岭塔河县二十二站林场开展星地同步验证试 验。 此次试验聚焦5米光学卫星、句芒号卫星及新一代海洋水色监测卫星的自然资源碳汇遥感监测能力，进一步深化国产遥感卫星在自然资 源调查、碳汇计量领域的实战应用，为提升大兴安岭典型地物碳汇计量精度提供关键技术支撑。试验利用高光谱卫星光谱信息与地面采集 数据比对，精准反演植被叶绿素等碳汇关键指标。为确保数据精度，技术人员精准对接5米光学卫星、新一代海洋水色监测卫星过境时间， 在二十二站林场同步开展森林、湿地植被光谱采集与样本采集，所有样本均送至实验室进行碳、氮、叶绿素等碳汇核心指标测定，同步采 集周边森林、湿地、大气指数样本，构建"卫星—地面"数据校准体系。 针对句芒号卫星"激光+多光谱+多角度+超光谱+偏振"的综合遥感优势，试验团队采用"卫星+无人机+地面"立体监测模式，完成合计 1200公顷样地的激光点云拍摄，以及10个卫星激光点落点样地内树木数量、种类、平均胸径及树高等 ...

Core Insights - The article highlights the integration of artificial intelligence and modern surveying technologies in Hunan Province, creating a comprehensive monitoring system that enhances governance capabilities and efficiency in natural resource management [2][4][10]. Group 1: Technological Integration - Hunan Province has developed a "Sky-Ground Network" monitoring system that integrates over 100 satellites and more than 200 drones, along with 25,000 video monitoring stations, to enhance real-time data collection and analysis [1][4]. - The "Investigation and Monitoring Brain" serves as the central hub of this system, incorporating six modules: perception, interconnection, scheduling, analysis, service, and management, which utilize AI, cloud computing, and big data [4][5]. - The system has achieved a fivefold increase in efficiency for intelligent detection and extraction of remote sensing changes, significantly improving data processing capabilities [1][6]. Group 2: Data Processing and Analysis - The integration of various sensing technologies allows for comprehensive observation of land parcels, enhancing the accuracy of agricultural monitoring and enabling real-time assessments of crop conditions [6][7]. - The data analysis capabilities have transformed from county-level statistics to a province-wide "one-click" analysis, reducing the time for data processing from three days to just 30 minutes [7][8]. - The system has developed over 300 ready-to-use business models to support precise decision-making in areas such as farmland optimization and conflict assessment [8]. Group 3: Proactive Governance - The monitoring system enables proactive risk management by capturing potential hazards in real-time and issuing alerts, thus enhancing public safety and emergency response [10][11]. - The "Iron Tower Sentinel" system has successfully identified and prevented numerous drowning incidents among minors by monitoring swimming activities and issuing alerts [10]. - In environmental monitoring, the system has facilitated rapid responses to natural disasters, such as floods and forest fires, by integrating satellite imagery and video data for timely action [11][12]. Group 4: Environmental Protection and Carbon Monitoring - Hunan Province is leveraging remote sensing technology to assess the carbon absorption capabilities of various ecosystems, with a reported transaction value of 81.39 million yuan from carbon credits [13][14]. - The "Ecological Easy Measurement" software enhances field verification processes by providing high-precision location data and integrating various ecological monitoring resources [15]. - The province's three-year action plan aims to further enhance the "Sky-Ground Network" system by integrating AI into monitoring processes, creating a scalable and customizable model for future applications [15].
