短句來源

     DISCUSSION ON THE ESSENTIAL GEOLOGICAL MODEL FOR LANDSLIDE

     試論滑坡基本地質(zhì)模型

短句來源

     Preliminarily Study on the Risk Analysis Methodology for Landsilde

     滑坡地質(zhì)災(zāi)害風(fēng)險分析方法

Taking the city proper of Wanzhou as the study area and ArcGIS as the platform,get all factors used in the hazard assessment of landslide into unitary processing and convert into quantitative data in uniform resolution.Then,adopting the evaluating unit of 50 m×50 m,operate by the logic regression model to assess the landslide hazard of this study area.The hazard map from this study coincides with the existing landslide distribution.

該文針對地質(zhì)災(zāi)害研究中的核心問題———災(zāi)害危險性評價,以萬州滑坡地質(zhì)災(zāi)害為例,將滑坡風(fēng)險評價中的各種因子歸一化處理后轉(zhuǎn)換成相同分辨率的定量數(shù)據(jù),根據(jù)特定模型進(jìn)行運算,得到風(fēng)險評價圖,利用邏輯回歸分析法,進(jìn)行滑坡地質(zhì)災(zāi)害危險性評價。以解決過去地質(zhì)災(zāi)害危險性評價中效率低、精度差、費時費力等問題,實現(xiàn)滑坡地質(zhì)災(zāi)害的信息化、科學(xué)化。
