| 摘 要： | 兰州是中国省会城市中地质灾害较为频发的地区之一,其地质灾害主要受地质、地形和人类活动等因素的影响。本文在分析兰州市区滑坡发育的控制因素和主要影响因素的基础上,以地理信息系统(GIS)为平台、采用专业数理统计软件SPSS中的逻辑回归模型(Binary Logistic)计算评价区内各单元格地质灾害的发生概率,通过GIS平台和SPSS软件之间数据格式的交换,利用GIS软件的空间分析功能,对兰州市滑坡灾害危险性进行了区划。研究结果与滑坡分布规律一致,对兰州市的地质灾害防治具有实际意义。

| Abstract: | Lanzhou is one of the frequent geological disaster regions among provincial capital cities in China,and its geohazard is mainly affected by such factors as geology,topography and human activities.Based on an analysis of controlling factors and main factors of landslide development in Lanzhou,and on the platform of GIS system,the authors used Binary Logistic of SPSS to calculate the probability of geological hazards in the unit of the evaluation region.Through the exchange between GIS software platform and SPSS data format and the utilization of the spatial analysis function of GIS software,the landslide hazards susceptibility was divided into different zones in Lanzhou.The results are consistent with the distribution of landslides and thus can play an important role in preventing the geological disasters in Lanzhou. |
