摘　　要：为有效开展崩塌滑坡等灾害的防控工作,将灾害损失降到最小,以3S技术为基础,针对吕梁地区崩塌滑坡地质灾害调查及特征展开分析。探究吕梁地区的地形地貌、气象水文和人类活动等背景信息;利用遥感、地理信息系统和全球定位系统技术,建立地质灾害数据采集与分析系统,针对吕梁地区崩塌和滑坡的演化模式进行分析研究,确定灾害危险区域;计算灾害参数间的拟合程度,分析幂律特征,明确崩塌滑坡和体积之间存在较强的相关性;将灾害点空间分布密度作为指标,划分不同区域的危险程度;分析灾害的时间分布特征,发现该地区的灾害频发时段为汛期。所提方法能够为地质灾害预防和控制工作提供依据,对于减轻灾害损失具有重要意义。In order to effectively carry out the prevention and control of collapse,landslide and other disasters,and minimize the disaster loss,based on 3S technology,the geological hazard survey and characteristics of collapse and landslide in Lüliang area were analyzed.Explore the background information of topography,meteorology,hydrology and human activities in Lüliang area.Using remote sensing,geographic information system and global positioning system,a geological disaster data collection and analysis system was established to analyze and study the evolution mode of collapse and landslide in Lüliang area and determine the disaster risk area.Calculating the fitting degree of disaster parameters,analyzing the power law characteristics,and confirming that there was a strong correlation between collapse and landslide and volume.Taking the spatial distribution density of disaster points as an indicator to divide the risk degree of different regions.By analyzing the time distribution characteristics of disasters,it was found that the period of frequent disasters in this area was the flood season.The proposed method can provide basis for geological disaster prevention and control,and is of great significance for reducing disaster losses.
