The group around ZHANG Bing has obtained breakthroughs in remote sensing of water quality parameters of lakes and reservoirs. Based on earlier data and remote sensing monitoring, long-term changes in the transparency of large lakes and reservoirs across the country since 2000 were realized. The “water color index” of China’s large lakes and reservoirs has generally shown a downward trend, indicating that the clarity of lakes and reservoirs in the west, especially the Qinghai-Tibet Plateau, has increased significantly. The clarity of eastern lakes and reservoirs rose less, which is attributed to climate change and water environment governance and protection measures.
