The optimization pattern of afforesative techniques with collecting runoff with collecting runoff to drough-resistance was presented by using L₉（3⁴）plan in the orthogonal experiments.It has shown that the order of four factors contributed to afforestative species(A)>cover material in the planted pits (D)>collection area of runoff for each tree(B)land preparation for afforestation(C).Of all factor,the order of the same kind is as follow;for A,Robinia pseudoacaia L.>Ulmus Pumila>Plalycladus arientalis Franco;For D,film>foam matcial>straw;for B,2.5m²>2.0m²>1.5m²;and for C,reverse slope terrace>level furrom>fish-scale pits.In semiarid loess hilly areas,the optimization pattern of afforestative techniques with collecting runoff to drough-resistance is A,D,B,C,Namely,afforeatative species is Rohinia Pseudoacacia L;the cover material of planted pits is film,the collectiom area of runoff for each tree is 2.5m²,and the land preparation pattern for afforestation is reverse slope terrace.
