Influence of Alpine Meadow Land Cover Differences on Precipitation-Runoff Processes on the Qinghai-Tibet Plateau, China
How land cover differences affect runoff and sediment and their relationship with precipitation are largely unknown on the Qinghai-Tibet Plateau. This study was designed to examine precipitation-runoff processes using the runoff observation plots on the 308 slope surfaces. Three plots were selected...

How land cover differences affect runoff and sediment and their relationship with precipitation are largely unknown on the Qinghai-Tibet Plateau. This study was designed to examine precipitation-runoff processes using the runoff observation plots on the 308 slope surfaces. Three plots were selected with vegetative cover average of 30, 68, and 93%. Our results show that runoff with 30% land coverage is larger than those with 68 and 93%, under the same precipitation form and amount in an alpine meadow. The mean sediment per precipitation event is two to four times greater in an area with 30% vegetative cover compared with those in 68 and 93% vegetative cover. Both runoff and mean sediment yields increased with vegetative cover from 30 to 68 and 93%. The precipitation form also affects the runoff and sediment yield.
