Soil nutrients of shrub sand-fixation forest in the Yulin sandy area were measured in this study.Results showed that shrub sand-fixation forest had a significant effect for soil improvement.Soil organic matter in windbreak and sand-fixation forest was increased obviously in the area and the soil nutrient status was improved considerably.Soil organic matter

total N

available P

and available K were increased by 2.2 to 20.6 times

2 to 22 times

0.7 times

and 41%

respectively.However

the pH of soil did not change significantly and presented an alkalescent condition.The study indicates that soil improvement in sandy land is a very slow process and soil nutrients of Yulin sand land still present a lean soil condition as a whole.
