Assessment of important attributes of soil and vegetation can help us to be aware of rangeland potential and help us to determine its situation. The goal of this research is to determine some plant and soil indicators of hilly winter rangelands of Eastern and Southern slopes of Chaharbagh region in Golestan province. By considering plant cover and soil surface attributes, it used the SSCC （soil surface classification） method to assess soil surface attributes. The length and width of ecological patches were measured in the forms of lichen, lichen-Grass, forbs, shrub and bare soil inter patches with litter. Also in this research, it measured the 11 soil surface parameters. These parameters are belonging to three main soil attributes stability, infiltration and nutrient cycles. These three indicators were measured in east and west of Eastern and Southern slopes of this ecosystem and showed significance differences （p 〈 0.05） in shrub, forbs and lichen-grass. In southern and especially in west aspect, these indicators in shrub were more than Eastern. But, in lossy hill of Eastern, lichen-grass patch is more significant. The most important ecological indicators of east landscapes of this region are forbs and lichen-grass.展开更多
