Abstract:: Through the analysis on 16 rocky slopes of Zhejiang Province which had already been ecological restored for one year, in the early vegetation recovery stage when there was no interactive development between vegetation and environment on the slope, the influence of slope angle and slope position on soil nutrient variability were as follow: (1) in some rocky slopes with slope degree of 45°～52°, available P content showed consistent trends: the lower slope position>the middle slope position>the upper slope position, and the total N, total P, total K contents of other rocky slopes varied significantly: the middle slope position>the lower slope position>the upper slope position; (2) in different slope positions with similar slope degree, the total N, total K contents and organic matter had no significant differences, but soil available nutrients had showed more remarkable differences in the multiple comparisons of soil nutrients; (3) in different slope angles with the same slope position, significant differences were only found in two groups in the multiple comparisons of soil nutrients, and there was no large-scale variability of soil nutrients. In other words, in the early succession stage of rocky slope revegetation, soil nutrients wouldn’t be significantly influence by slope angle ranging from 30° to 52°.
