- Abstract:
-
Impoundment of the Three-gorge Reservoir (TGR) has formed 349 km2 riparian zones with a 30 m annual water level fluctuating between 145 m and 175 m. Severe soil erosion has taken place within riparian landscape as the results of overlaid hydrological alternations, vegetation replacement and soil physic-chemical changes. How to restore the vegetation becomes a regional hot spot issue. Through the system summary on the scientific research practices and experiences of the vegetation reconstruction in Three-gorge Reservoir, the vegetation reconstruction basic strategy and ways are proposed in this study. Meanwhile, the soil erosion of different vegetation reconstruction was observed by erosion pins. The results show that the planted grass can reduce the soil erosion by 74%, followed by 55% in the natural grassland. The soil erosion intensity of traditional farmland is 11% higher than the control because of the intensive artificial disturbance in surface soil.
