Other Abstract

Sediment discharge significantly decreased in the Yellow River because of the effect of the‘grainfor-
green project’(GGP).The typical watershed parsing method was applied to obtain the sediment yield
and analyze the variation of the annual erosion modulus in a typical watershed in the loess hilly-gully region
between 2003and 2011.The results indicated that sediment yield from the watershed declined dramatically,
and the average erosion modulus was less than 500t/(km2·a),which was 8.3%of that before the implementation
of GGP.Moreover,when excluding the data in 2003because of the influence of the beginning of
dam implement,the average erosion modulus during 2004-2011was 144.93t/(km2·a),which was only
2.4%of that before the implementation of GGP,suggesting that there was a mild erosion in this watershed
after the GGP.This study proved the significance of the effects of controlling sediment yield of the GGP,and
it may help the planners and managers to make proper decisions for the control of soil erosion from watersheds
under similar conditions.
