摘要/Abstract

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 analyze 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.
