摘要

Aiming at the complexity of ecological environment risk of flood disaster,the life cycle of flood disaster is defined based on the relevant literatures,which is divided into incubation period,development period,outbreak period,recession period and extinction period.The characteristics of each period are analyzed.Further,the main risks for ecological environment faced at each stage under the life cycle of flood disaster are studied systematically to form the systematic ecological environment risk system for flood disaster.
