The rapid urbanization along with intensive construction activities, strongly changes the natural landform and the stable geological environment, which leads to increasingly frequent landslide disasters. Taking Shenzhen as the research area in this study, the ecological risk of street scale landslide disaster was evaluated based on the three-dimensional evaluation framework "Risk-Vulnerability-Potential loss". The visual risk structure of "three primary colors" was applied while the uncertainty analysis was carried out by Monte Carlo simulation. Then the ecological risk management measures were proposed. The results show that: (1) There was a significant negative correlation between the uncertainty and the evaluation area. As the evaluation area increased, the uncertainty of ecological risk sources decreased. (2) For the ecological risk assessment where risk source is the main uncertainty, the uncertainties are jointly determined by the ecological risk source uncertainty and the value of the extrinsic factor which is the sensitive factor of the ecological risk uncertainties. (3) The ecological risk of landslide disaster in Shenzhen presents a structure of "low-high-low-high" from west to east. The risk structures are mainly of the "high vulnerability-high potential loss" type and the "high risk-high potential loss" type. The analysis of ecological risk structure, the establishment of an ecological risk management system for landslide disaster and the development of clear risk management objectives are conducive for the effective management of ecological risk.
