摘要
///The methods for regional landslide hazard assessment still have many aspects that are need to be improved. Based on engineering geological analogy and QR decomposition, using the area density of landslide to describe the landslide hazard, an algorithm that uses high order polynomial to fit the relationship between the hazard-inducing factors and landslide hazard was presented. Then, combining this algorithm, analytic hierarchy process and conditional probability model an improved regional landslide hazard assessment model was established. Then, a software was developed to realize this model under the Visual Studio. Net C# environment and using ArcEngine Components. Finally, Linyou County in Shanxi Province was selected as an experimental area to do the landslide hazard assessment. Checked by the actual data, this model has a high reliability and can be used in the future.
