- 摘要:
- Rivers are one of the most dynamic components of the water cycle on Earth's surface and play a significant role in the development of human societies, ecosystem sustainability, and regional climate. However, their natural balance has been threatened by human disturbances and ongoing climate change, as evidenced by changes in river extent over recent decades. In order to better understand what is behind these changes, researchers led by Prof. SONG Chunqiao from the Nanjing Institute of Geography and Limnology of the Chinese Academy of Sciences and their collaborators from China and the United States have analyzed water extent variations using four decades' worth of Landsat imagery in order to globally attribute recent changes in river regimes to morphological dynamics or hydrological signals.
