中文摘要:

为了对野外风险斜坡及潜在地质灾害进行快速识别，现基于斜坡单元采用信息量模型对贵定县宝山至盘江重点区开展地质灾害风险评价，并分析地质灾害分布与风险斜坡的相关性。结果表明:1风险评价结果中极高风险斜坡42处，高风险斜坡308处，中风险斜坡580处，低风险斜坡280处，分别占比347%、2545%、4793%及2314%；2地质灾害主要分布于极高及高风险斜坡，低风险斜坡中无地质灾害分布；3通过对比评价结果与研究区实际情况，表明风险评价结果较为合理，信息量模型可以应用于山地斜坡地质灾害风险评价，同时评价结果为下一步指导地质灾害防治工作提供了重要的信息及依据。

英文摘要:

In order to quickly identify the risky slopes and potential geological hazards in the wild，the information model is used to carry out the geological hazard risk assessment in the key areas from Baoshan to Panjiang in Guiding County based on the slope unit，and the correlation between the distribution of geological hazards and the risky slopes is analyzedThe results show that: 1In the risk assessment results，there are 42 extremely high-risk slopes，308 high-risk slopes，580 medium-risk slopes，and 280 low-risk slopes，accounting for 347%，2545%，4793%，and 2314%，respectively2Geological hazards are mainly distributed in extremely high and high-risk slopes，and no geological hazards are distributed in low-risk slopes3By comparing the evaluation results with the actual situation in the study area，it shows that the risk evaluation results are reasonable，and the information model can be applied to mountain slope geological disaster risk assessment，and the assessment results provide important information and accordance for the prevention and control of geological disasters in the next step
