Abstract：
In this paper,the parton evolution model is improved by using the modified Alteralli-Parisi equation which can describe the nuclear shadowing and anti-shadowing effects in the small x region.Within the theoretical framework of the improved parton evolution model,the unified description of the EMC effect,and nuclear shadowing and antishadowing effects is given without introducing the nuclear shadowing factor.
