The Grain for Green Project (GGP), which was implemented in China since 1999, has achieved remarkable achievements, but some new issues have gradually emerged, and it is necessary to carry out scientific evaluation and systematic sorting. In order to provide scientific basis for the ecological construction and high-quality development of the Loess Plateau in the new period, this paper comprehensively evaluated and analyzed the achievements and problems of afforestation and grassland construction in Yan' an City after the implementation of GGP, and put forward specific countermeasures and suggestions based on the field investigation and remote sensing image interpretation of typical years from 1990 to 2020. The achievements obtained by the implementation of GGP in Yan' an City are as follows: ecological quality has been improved obviously, land use structure has been adjusted rapidly, agricultural industrial structure has been adjusted, fanners have been lifted out of poverty and become rich, forest and grassland area has been rapidly enlarged and vegetation recovered well. The problems in vegetation construction that Yan' an City currently faced are: vegetation restoration on a large scale has changed surface hydrological processes ( limited precipitation is expended through evapotranspiration, and is not conducive to subsequent stable growth of established vegetation and the ecological service function of continuous play), forest types are single during afforestation, artificial grassland construction scale has limitations, and large area of natural grassland needs to be reasonably explored. Suggestions for vegetation construction in Yan' an City in the future: to carry out comprehensive evaluation and planning of regional agriculture, to strengthen ecological effect monitoring and evaluation of GGP, to optimize forest stand and tree species step by step, to strengthen tending management and rational utilization of natural grassland, and to support and build animal husbandry sustainable development system.
