Abstract:The evolvement and the effect process of the chain-styled phases in the disaster are mainly represented by the shape characteristics. The shape characteristics are extended to some aspects,such as the extrinsic effect characteristic,the abnormality reflection of the parameters,the translation characteristic of the carrier communication,the fragmentation effect of the acting force,and so on. The shape characteristics are catalogued as the inchoate,medium and terminal effect degrees by administrative levels. The evaluation mode with several levels,several factors and standardization are formed. In the validating application of the mode,according to the data,the quantizing results about measuring of the chain-styled phases of the disaster are obtained by the evaluation proportion of the logic relations of the several factors in the disaster process.
