摘    要:本文针对泰山地区泥石流发生的原因和特点进行了初步分析,并对危害最严重的泰安市岱岳区下港乡进行泥石流危险度区划研究。采用GIS技术,通过缓冲区分析和叠加分析等运算,获得研究区评价单元的危险度评价指数,并以该指数为依据采用分位数理论进行危险度的划分,将研究区危险度划分为四级,找出了当地泥石流危险性最大的区域。本文不仅较好地将GIS技术应用到了泥石流危险度区划的研究中,而且区划结果也可以为当地土地利用规划等决策提供一定帮助。

关 键 词:泥石流  危险度区划  山东下港  GIS

Abstract:In 2000,debris flows happened in the Mountain Tai area,damaged seriously.But because there are few debris flows happened in Shandong province,the study on this field is almost a blank.This paper analyzed the causation and character to the debris flows in Mountain Tai area,and used GIS(Geographical Information System) as tools,by buffer and overlay analysis,get the value of every cell,then based on it,assessed the risk grade of Xiajiang-the most serious area.At last,the most dangerous areas were found.This research not only used the GIS tools perfectly but also gave a reference to others' study.
Keywords:debris flows   risk assessment   Xiajiang of Shandong province   GIS
