Abstract:Effects of forest vegetation and small watershed ecological recovery on water and sediment variations in Beiluo River basin were studied.Results showed that forest vegetation could reduce runoff and sediment by 62.4% and 94.9%,respectively.Meanwhile,it regulated the annual distribution of runoff and released 20%~30% of runoff from flood season to nonflood season.However,flood sediment in forest region increased drastically under the effect of storm flood when forest was destroyed.In view of the effects of ecological recovery on water and sediment variation,the ecological recovery had a certain role in reducing water and sediment.
