Abstract: Authors analysed shady slope soil nutrients in three returning farmland to forest vegetation (Hippophae rhamnoides,Hippophae rhamnoides+Pinus tabulacformis, Hippophae rhamnoides+Robina pseudoacacia) which were in different growth status in hilly region of Loess Plateau, the results showed:(1)The soil nutrients were very low in study area; (2) The spatial variation of total nitrogen,available nitrogen, available potassium, available phosphorus was obvious in study area;(3) The order of the soil nutrients in the study area from big to small was Hippophae rhamnoides(good)>Hippophae rhamnoides+Robina pseudoacacia(good)>Hippophae rhamnoides(bad) >Hippophae rhamnoides +Robina pseudoacacia (bad)>Hippophae rhamnoides +Pinus tabulacformis (good)>Hippophae rhamnoides+Pinus tabulacformis(bad). The soil nutrient of Hippophae rhamnoides+Pinus tabulacformis（death）was better than good and bad one.
