| Abstract: | Abstract Changes in development and use of water resources over the last 30 years have led to significant environmental and hydrological degradation of the River Heihe basin in the People's Republic of China. Water discharge of the lower reaches has been seriously compromised and more than 30 tributaries and terminal lakes have dried up. The water output of springs has dropped significantly. Also water quality problems have been observed, in both surface waters and groundwater. Hydrological changes have resulted in a marked degradation of aquatic habitats, and have caused substantial, and expanding, land salinization and desertification. Solving these problems, which have been largely caused by human activities, requires massive and long-lasting concerted efforts. |
