| 摘 要： | 利用地理信息系统（GIS）与遥感技术结合进行油坡灾害评价与预测是当前滑坡研究的热点，在对浙江省庆元县进行遥感滑坡研究中，通过对滑坡各影响因素的详细分析。结合TM图像，利用GIS技术分析主要影响因素，确定影响因素集及其间的朴素关系。从而建立庆元县油坡灾害多要素综合评价的初步模型。结果有81.25%滑坡点落在危险区域。令人比较满意，因此，可以利用此模型进行庆元县滑坡灾害评价。

| Abstract: | In recent years, remote sensing technology and GIS (Geographical Information System) technologies are developing fast, widely used in the researches on landslide hazard evaluation and prediction. The authors conducted a detailed study to analye the triggering factors that could cause the landslides in Qingyuan region, Zhejiang Province, and their relationships with GIS and TM image technologies. A new evaluation model is established based on our analysis, and the simulation results are in accordance with the facts of the study area, i.e. 81.25% of the landslide sites are located in the dangerous zones of the evaluation map. Therefore, this model can be used to evaluate the landslide hazard in Qingyuan region, Zhejiang Province. |
