| 摘 要： | 建立灾害体的3D仿真模型，提取泥石流灾害体的特征信息；对信息进行归一化处理，并对其进行等级划分和赋值。建立“灰色类别模型”，对古乡沟泥石流进行危险性评价。灾害体的危险性评价结果与前人实地调查的情况基本吻合，具有较高的准确性，能够为防灾避难提供科学依据。

| Abstract: | The 3D Remote Sensing image models of debris flow disaster is constructed for interpretation, normalization, classification and evaluation of the disaster feature information. The ＂Grey Class Model＂ is constructed, and then the danger degree has been assessed on Guxiang gully debris flow. The evaluation is almost consistent with what experts have been investigated previously, and the result is greatly reliable to provide the scientific avoiding disaster datum for people. |
