Abstract
Monitoring of changing lake and wetland environments has long been among the primary focus of scientific investigation, technology innovation, management practice, and decision-making analysis. Floodpath lakes and wetlands are the lakes and associated wetlands affected by seasonal variations of water level and water surface area. Floodpath lakes and wetlands are, in particular, sensitive to natural and anthropogenic impacts, such as climate change, human-induced intervention on hydrological regimes, and land use and land cover change. Rapid developments of remote sensing science and technologies, provide immense opportunities and capacities to improve our understanding of the changing lake and wetland environments. This special issue on Remote Sensing of Floodpath Lakes and Wetlands comprise featured articles reporting the latest innovative research and reflects the advancement in remote sensing applications on the theme topic. In this editorial paper, we review research developments using state-of-the-art remote sensing technologies for monitoring dynamics of floodpath lakes and wetlands; discuss challenges of remote sensing in inventory, monitoring, management, and governance of floodpath lakes and wetlands; and summarize the highlights of the articles published in this special issue.
Highlights
The needs for satellite-based observation of terrestrial aquatic ecosystem has for long received the attention of the world [1,2]
Satellite altimetry sensors have been applied in monitoring water extents, heights, and flows [21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36]
The Poyang and Dongting lakes in the middle and lower reaches of the Yangtze River are among the representative floodpath lakes with dramatic spatial and temporal variation patterns in water surface areas and the associated wetlands
Summary
The needs for satellite-based observation of terrestrial aquatic ecosystem has for long received the attention of the world [1,2]. The Poyang and Dongting lakes in the middle and lower reaches of the Yangtze River are among the representative floodpath lakes with dramatic spatial and temporal variation patterns in water surface areas and the associated wetlands. Different types of remote sensing data have been applied to reveal the spatial and temporal patterns of water extents and levels and the responses of vegetation and habitats, as well as the effects of sand dragging, sedimentation, and the contamination of this unique floodpath lake/wetland combination [66,67,68,69,70,71,72,73,74,75,76,77,78,79]. Challenges remain to be addressed for the advancement of the science, technologies, and the management practices [115,116]
