| Abstract: | 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. |
