摘要
利用地理信息系统 (GIS)与遥感技术结合进行滑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相互关系 ,从而建立庆元县滑坡灾害多要素综合评价的初步模型 ,结果有 81.2 5 %滑坡点落在危险区域 ,令人比较满意。因此 。
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.
