| 摘 要： | 基于易损性系由受灾体自身内在性质所决定的认识，论述了山坡泥石流场地易损性的构成要索，即受灾体遭受山坡泥石流破坏机会的大小和造成损毁的难易程度。前者与受灾体和泥石流的相对空间位置等因素有关，后者主要受受灾体物质成分、结构和状态等的影响。在此基础上，提出了山坡泥石流场地易损性评价模型，并给出了评价实例。 |

| Abstract: | Based on the realization that hazard affected objects' vulnerability is decided by its own nature,this paper discusses the composed elements of vulnerability,which includes two parts.One is the possibility to be affected;the other is the easiness to be damaged.The former has a bearing on the relative distribution distance,collective degree and slope conditions,and the latter is affected by hazard affected objects' material,construction,character and so on.Then mathematic model for vulnerability assessment of hill slope debris flow is put forth,which has been applied to Beibei District of Chongqing City. |
