| 摘 要： | 利用组合权重法将地质灾害易发区等级和降雨量等级进行有机的结合，建立了基于组合权重的汛期地质灾害预警预报模型。以吉林省为例检验其有效性。将研究区域剖分为5 702（5 km×5 km）个单元格，对每个单元格的地质灾害发生的可能性进行了等级预报。通过对已发生的地质灾害及降雨量的历史资料进行验证可知，该预报结果的精准率达到了93.25%，其预报结果是合理可行的。 |
| 关 键 词： | 组合权重 降雨量 地质灾害 预警预报 |

| Abstract: | The authors divided grades for the geological disaster-prone zone and rainfalls by weight method, and established a flood warning and forecasting model of geological disasters based on combination weights. Its effectiveness was tested for taking Jilin Province as an example. The study area was subdivided into 5 702 (5 km × 5 km) cells, and the possibility of geological disasters in each cell was forecasted in grade. By using the historical data of geological disasters and rainfalls, the forecast results are verified and the accurate rates reach 93.25%, which is reasonable and feasible. |
| Keywords: | combination weights rainfall geological disasters warning and forecasting |
