| 中文摘要: |
| 本文以甘肃张掖市土质滑坡为依托，从易发性、危险性、易损性 3个方面，构建评价指标体系和评价模型，对土质滑坡风险进行综合评价。结果显示，低风险土质滑坡的滑坡体体积较小，通常发生于地形平坦区域，一般不会对经济、人口、物质造成影响；中风险土质滑坡的滑坡体体积适中，通常发生于缓坡或山丘上，一定程度上会对经济、人口、物质造成影响；高风险土质滑坡的滑坡体体积较大，通常发生于陡峭山坡或深谷中，且对经济、人口、物质具有严重影响。该结果与张掖市历史土质滑坡风险等级划分情况一致，具有正确性、有效性和可靠性。 |
| 英文摘要: |
| Based on the soil landslide in Zhangye City，Gansu Province，this paper constructs the evaluation index system and evaluation model from the three aspects of susceptibility，risk and vulnerability，and makes a comprehensive evaluation of soil landslide risk. The results show that low-risk soil landslides have small volumes， usually occurs in flat terrain areas，which generally have no impact on the economy，population，or material resources；Medium risk soil landslides have moderate volumes，usually occurs on gentle slopes or hills，which will have an impact on the economy，population，and material resources to some extent；High risk soil landslides have large volumes，usually occurs in steep slopes or deep valleys，and have serious impacts on the economy，popula. tion，and material resources. |
