Ecological management was investigated and demonstrated on the 185 m observation platform with-in the water-level-fluctuating zone of the upstream Three Gorge Reservoir. This study addressed the current adverse situation： the side slopes between the two critical elevations(145-152 m,170-177 m) has experi-enced destructive surge erosion. The cause of surges and their erosion mechanism were analyzed. It was found that surges were the main force causing soil erosion. Traditional slope reinforcement measures and eco-logical techniques like riparian zone construction should be combined organically. Several feasible ecological restoration measures were proposed in respect to slopes of various gradients. In addition, an ecological resto-ration modes for the slopes between the two important elevations in the fluctuating zone was developed pre-liminarily.
