摘要:
长三角一体化先行启动区是打造生态绿色高质量发展的标杆地。无人机遥感以其灵活、高效的特性，能够为先行启动区生态建设提供重要支持。结合原位实测光谱与透明度数据，构建适用于研究区的透明度反演模型，利用高光谱相机获得54 km2的无人机航拍影像，开展先行启动区透明度遥感监测研究。经验证，透明度反演模型在验证集上的均方根误差为6.7 cm。将透明度反演模型应用于航拍影像，获得了透明度空间分布状况，其中透明度较低水域为养殖塘，较高水域为圩区内小型河道。根据光谱分析发现，透明度较低水域的致浊物质有所区别，养殖塘和湖荡的致浊物质主要为藻类。太浦河两侧水闸在一定程度上削弱了太浦河水对圩区内部水体透明度的影响，部分水闸两侧的透明度相差30 cm左右。
Abstract:
The pioneer zone for the integrated development of the Yangtze River Delta is a benchmark for advancing eco-friendly and high-quality development. Unmanned Aerial Vehicle (UAV) remote sensing, with its flexible and efficient characteristics, can provide significant support for the ecological civilization construction in the pioneer region. By integrating in-situ measured spectral and water transparency data, a transparency retrieval model was developed for the research area. A UAV hyperspectral image covering 54 km2 was acquired to monitor the spatial distribution of water transparencyin the pioneer region. Validation results showed that the root mean square error (RMSE) of the transparency retrieval model on the validation set was 6.7 cm. Applying the transparency retrieval model to the aerial imagery revealed the spatial pattern of transparency, identifying low-transparency water bodies as aquaculture ponds and high-transparency ones as small rivers in the polder area. Spectral analysis indicated differences in turbidity-causing substances among low-transparency waters, and the turbidity agents in aquaculture ponds and lakes are algae. A transparency difference of approximately 30 cm was observed on either side of a water gate, suggesting that such hydraulic structures have reduced the impact of water from the Taipu River on the rivers inside the polder area.
