吞吐型湖泊湖滩的地形遥感反演方法—以中国江西省鄱阳湖为例
Bathymetry Mapping of Alternately Filled Lake Using Multi-Temporal Satellite Images
摘要: 吞吐型湖泊局部地貌变化快速，水动力环境复杂，较为准确、快速地获取吞吐型湖泊湖滩地形信息对于相关湖滩研究、湖滩管理保护与发展具有重大意义。研究基于多时相遥感影像，反演鄱阳湖(典型吞吐型湖泊) 2010年湖滩地形。研究从2010年33幅具有相对连续水位信息的遥感影像中获取水边线；将水边线离散成点后与相应时刻的水位信息内插，进而构建湖滩DEM。通过相对比较与绝对比较的方法进行验证，结果表明：采用该方法构建的鄱阳湖湖滩DEM垂直误差为25.1 cm，精度满足要求。因此，该方法对于构建吞吐型湖泊湖滩地形具有一定适用性。
Abstract: Alternately filled lake is known for its rapid change terrain and complex hydrodynamic environ-ment. More accurate and rapid access to its topographic map is of great significance to relative research, management, protection and development of its lake beach. This paper tries to derive the bottom topography of Poyang Lake (a typical alternately filled lake) in 2010 based on multi-temporal satellite images. To build the lake beach DEM, waterlines were detected using 33 satellite images acquired at continuous elevations in 2010, and then discretized to point to interpolate with water levels at corresponding moment. Both relative and absolute validation results show that the average height error of DEM derived using this method is 25.1 cm, which is within the precision requirement. All of these findings proved the feasibility of this method to construct the topographic map for alternately filled lake.
