Abstract：Resulting from the tendency toward self-rehabilitation appearing in present vegetation construction in the Loess Plateau, the paper discusses tactics of vegetation restoration such as self-rehabilitation, growing grass or shrub as the first step to restore forests, planting suitable trees in accordance with site conditions for afforestation, and proceeding from suitability between plantation and site for afforestation and so on, in order to clarify some problems. It is considered that the tactics that suitable trees are planted in accordance with site conditions for afforestation would not be wrong. Implementing it and integrating artificial construction with self-rehabilitation to construct vegetation is advisable, but it would be difficult that forests are expected to be restored just like natural succession by growing grass or shrub in advance. The analysis showed that the standards to afforest at suitable site with suitable tree are needed to be studied further. At last, the paper also discussed the connection of the vegetation zonality principle and afforestation of suitable site with suitable tree.
