[Objective] The objective of this study is to analyze the effect of slope ecological protection measures in western part of Huangqiba section in northern of Xinjiang Uygur Autonomous Region

in order to provide the scientific basis for regulating vegetation succession rate and expected vegetation restoration effect.[Methods] We investigated soil and vegetation conditions in the canal slopes caused by excavation and natural habitat at the top of channel.[Results] (1) After ecological restoration

the plant density

coverage

evenness index(Pielou)

diversity index(Shannon-Wiener) and richness index(Margalef) in the sunny and shady slope has been improved

and the improvement in shady slope was higher than in the sunny slope

but still lower than the natural habitats. (2) Soil nitrogen

phosphorus

potassium nutrient characteristics in both shady slope and sunny slope were increased

however

they were still lower than the level of natural habitats

which showed as:the natural habitat > shady slope > sunny slope. (3) After the ecological restoration

the plant community index of the shady and sunny slope was still low

and the community succession was still in the stage of shrub and grass plant community.[Conclusion] The slope ecological restoration technology can improve the soil fertility status and promote the growth of vegetation on the side slope. Due to the special environmental conditions of the west main canal area

short-term ecological restoration measures is not enough and long-term restoration is needed. In addition

native plants should be selected in the slope ecological restoration plant in the northern area of Xinjiang region.
