Abstract:AimTo provide technological reference for the recovery of ecological environment and the construction of forestry ecological engineering on Loess Plateau.MethodsInvestigating and analysising the technical problems occurred in the engineering of returning the grain plots to forestry.ResultsA project of vegetation recovery techniques on sloping returned grain plots is given in the northern area of Shaanxi, including the selection of excellent afforestation tree and grass species, the arrangement technique of forest categories and tree species, the afforestation techniques on drought-resistance, the afforestation techniques on mixture forest and so on. The expected economical, ecological and social benefits are estimated in the end.ConclusionThe project can provide technological reference for the recovery of ecological environment and the construction of forestry ecological engineering on Loess Plateau.
Keywords:loess plateau  sloping returned grain plots  vegetation recovery  benefit evaluation
