2009年至今，褐潮在我国秦皇岛海域连续6年发生，分布面积达数千平方公里，我国成为继美国、南非之后全球第三个发生褐潮的国家。连年爆发的褐潮，给当地扇贝养殖业和生态环境造成了严重影响，直接经济损失上亿元，成为海洋管理和公众关注的热点问题。由于缺乏对褐潮光学性质的了解和有针对性的褐潮遥感监测方法研究，目前褐潮业务化监测完全依赖现场船舶走航观测，监测效率低，且人力、物力耗费巨大。. 本项目拟充分发挥高光谱遥感精细监测，无人机机动灵活、不受云层遮挡的优势，开展褐潮无人机高光谱遥感监测技术研究：通过获取褐潮海空同步立体观测数据，揭示褐潮不同发展阶段的生物光学性质及环境影响，遴选褐潮特征参量，建立褐潮高光谱遥感检测模型，实现基于无人机高光谱的褐潮高精度检测，为褐潮业务化监测和防灾减灾提供技术支撑。

Since 2009, brown tide has taken place continuously for 6 years along the coast of Qinhuangdao, with the distribution area of thousands of square kilometers, making China be the third country brown tide occurred in after United States and South Africa. The consecutive occurred brown tide significantly damaged the mariculture industry and marine ecological environment, causing a direct economic loss of hundreds of millions yuan. Thus it has become the hot topic. For the lack of understanding of the brown tide optical properties and detection method, the brown tide operational monitoring, at present, completely depend on the field observation, which is inefficient and needs more manpower and resources.. This project intends to make the best use of hyperspectral and UAV and develop the brown tide monitoring technique based on UAV hyperspectral. By obtaining sea and air sync stereoscopic observation data of brown tide, this project will reveal the optical and biological properties of brown tide at different age and its environmental impact. The characteristic parameter of brown tide will be selected. Then the high precision detection method for brown tide on UAV hyperspectral will be finally implemented. The production of this project will provide technical support for brown tide monitoring and disaster mitigation, prevention.
