Brittleness Source Control of Disaster System about Middle and Lower Reaches of the Yellow River
黄河中下游灾害系统的脆性源控制

The brittleness theory of complex system is applied to the study of disasters of the Yellow River for the first time.According to the definition and quantified characteristics of brittleness and the system dynamics,the disasters of middle and lower reaches of the Yellow River are analyzed deeply by modeling of natural disasters via chain reaction mechanism.Further more,some measures are put forward against the disasters according to the present status of middle and lower reaches of the Yellow River.
