Using the remote sensing technique, that is, by using false colour satellite image interpretation, we find out the present situation of soil and water conservation in Dabieshan mountains in Anhui Province and put for-ward the way to control the loss in policy and step. Especially, the forest for containing water should be planed in the upper area of six large reservoirs in Anhui Province in order to adjust the rainfall by nature and man-made ways. This benefits is preventing flood in reservoir area as well as strengthening agricultural reserve forces in Pi-Shi-Hang area, and obtaining social and ecological results on a grand scale.
