Abstract: The ecological slope protection has been widely applied and developed at home and abroad. By means of recalling the previous model test of ecological slope stability research, the classification expands from the lead to slope failure factors of gravity action, washing action, water infiltration erosion action, wind erosion action and seismic or other forms action. The paper introduces present research situation of the ecological slope stability model, contrasts and relates the merits of some ecological slope stability model test research. Some inadequacies of the ecological slope stability model tests are put forward and the future development trends of the ecological slope stability research are also expected.
