凌源市是辽西地区山地地质灾害危害较为严重的区域.在GIS技术支持下,选取地形、岩性、构造、降雨、道路、土地利用等6个因素作为评价指标,根据已发生的68个山地地质灾害点计算了各指标因子的敏感性,分别采用层次分析法、信息量法和统计量法确定了各指标的权重,利用因子叠置法对危险性进行了综合评价.结果表明层次分析法在该区山地地质灾害危险性评价中效果良好.该研究对相似地区山地地质灾害危险性区划具有一定的借鉴意义.
凌源市是遼西地區山地地質災害危害較為嚴重的區域.在GIS技術支持下,選取地形、巖性、構造、降雨、道路、土地利用等6箇因素作為評價指標,根據已髮生的68箇山地地質災害點計算瞭各指標因子的敏感性,分彆採用層次分析法、信息量法和統計量法確定瞭各指標的權重,利用因子疊置法對危險性進行瞭綜閤評價.結果錶明層次分析法在該區山地地質災害危險性評價中效果良好.該研究對相似地區山地地質災害危險性區劃具有一定的藉鑒意義.

Lingyuan City lies in the west of Liaoning Province where mountain geological disasters frequently occur. Based on GIS, six indices, i. e. , topography, lithology, structure, rainfall, land-use type and road are selected for the assessment of geological disasters. The sensitivity of various indices are based on 68 historically happened disasters, and the weights of the factors are determined by information models, statistical models and analytic hierarchy process (AHP) separately. The synthetic appraisal of mountain disasters in Lingyuan City is carried out by factor overlay method. The results indicate that the AHP is obviously advantageous in the probability assessment of regional mountain disasters. The research is helpful in the zonation of mountain disasters assessment of similar areas.
