It is one successful method to use suspended sedim ent load in the Yellow River to improve saline and alkali soil

aeolian soil to increase land productivity

but also one most significant human activity to dist urb the landscape ecosystem in the lower reaches. Based on the outdoor investiga tion and sampling

through researching on the amount and distribution of used su spended sediment load

this paper systematically analyzed the impact of suspende d sediment on soil texture

fertility and salinity motion

as well as landscape ecosystem. Meanwhile

we should pay close attention to aggrieving cropland

seco nd-salinization

second-desertification

restarting flood drainage etc caused by using suspended sediment load when we enjoy the great accomplishment of using the Yellow River.
