The southmountainous area of Changqing district is one of regions that supplying surface water and groundwater of Jinan city,so it is necessary to monitor and manage the region for ensuring the water safety of Jinan city.In this paper,soil and water loss of study area was researched using the revised universal soil loss equation(RUSLE)based on geographical information system(GIS)and remote sense(RS)technologies.Intensity of soil and water loss is low on the whole,and high intensity areas are found in the mountainous area.Intensity of soil and water loss is affected by 1and use type.and soil and water loss of grassland type have high intensity feature.Some suggestions are given according to four management patterns.
