无人机航测技术在潮白河生态补水中的应用

Application of UAV aerial survey technology in ecological water replenishment of Chaobai River

针对2021年度首次实施的潮白河较大规模试验性生态补水,应用无人机航测技术,对补水区域内的白河、潮河、潮白河潮汇大桥至向阳闸河段、雁栖河及怀河等主要补水河道进行了航测,获取了补水后主要补水河道的水面面积变化、潮白河向阳闸库区三维数字地形,并精确计算了向阳闸库区的河道日入渗量,为科学评估生态补水对潮白河水环境与水生态影响、摸清潮白河地下水回补入渗规律等工作提供了扎实的数据基础.

Aiming at the large-scale experimental ecological water replenishment of Chaobai River implemented for the first time in 2021, the Unmanned Aerial Vehicle(UAV) aerial survey technology was carried out on Bai River, Chao River, Chaohui bridge to Xiangyang sluice of Chao Bai River, Yanxi River, Huaihe River and other river courses in the water replenishment area, the changes of water surface area of the main river channels before and after water replenishment, and the 3D digital topography of Xiangyang sluice reservoir area of Chaobai River were obtained, and the daily infiltration of the river channel in Xiangyang sluice was accurately calculated, the study provides a solid data basis for scientific assessment of the impact of ecological water supplement on Chaobai River environment and water ecology, and for finding out the law of groundwater recharge and infiltration of Chaobai River.
