Abstract：Based on the dendrogeomorphological method and soil erosion rate temporal variation analyze method,the soil erosion rate of 4 representative distracts in Hebei mountains around Beijing were researched.The results showed that the erosion intention of research points were all above middle degree erosion.Most of the research points were very intensive erosion or violent erosion.The soil erosion rate was related to slope, geomorphology, lithology, vegetation conditions and human activity.These research points as follows were easy to occur very intensive erosion or violent erosion, such as human activity district, steep slope district, foothill district, clastic rock district, diabase district, limestone district, gneiss district or loess-like soil district and tree or undergrowth sparse areas.The results of the same slope surface showed that the soil erosion was the most sensitive to slope and human activity, then was vegetation conditions and geomorphology.The results of points with different tree ages showed that the soil erosion rates in the last hundred years had a considerable increase.For all-round management of water and soil erosion, the sensitiveness zone of soil erosion in Hebei mountains around Beijing should be comprehensively designated,and the zonal and hierarchic control should be carried out.
