‏ بررسی عوامل موثر بر حرکات توده‌ای برپایه تهیه نقشه‌های پهنه‌بندی خطر زمین‌لغزش ‏‏(مطالعه موردی: ارتفاعات دنای زاگرس)‏‎

Regarding their nature and their variety, and hazards that landslides have for humans life and properties, landslides have always been the ‎center of attention and study by scientist from different fields of study such as geology, engineering geology, geomorphologies. these ‎phenomena have a complex mechanism and different factors and variables could be effective in their occurrence, the numerous studies have ‎been done to recognize the effective factors, classification, zonation and modeling. accordingly, it was tried to study the landslides in ‎kahredan basin in northern part of semirom, dena mountain in zagros zone suburban area in isfahan province and provide a landslide ‎hazard zonation map by using the statistical method and the hazard map which has the most accuracy and precision will be selected. so ‎finally it was specified the order of effective parameters in landslides. according, by selecting following six parameters including to slope ‎aspect, lithology, land use, rainfall and distance to drainage, it was provided landslide inventory map by using following four methods. ‎information value, linear regression, discriminate analysis and area density. the statistical method of information value was recognized the ‎best method of landslide hazard zonation which is capable of using in planning and urban developments. the effective parameters in ‎landslides according to their importance are including to lithology, distance to drainage, land use, slope, aspect and rainfall respectively. ‎
