【摘要】 地理信息系统(GIS)在断层与滑坡相关性分析中已得到普遍的认可和使用,最为常见的是基于缓冲区分析和叠加分析建立统计模型,对断层距和滑坡数量进行统计。但在模型建立的过程中存在这样的问题:采用多大缓冲距离建立的统计模型,它的统计结果能恰当的反映断层和滑坡之间的相关关系。为解决这个问题,以陇南山区的断层和滑坡为研究对象,基于Pearson法分析了不同大小缓冲距离的统计模型,对研究断层和滑坡之间相关性的影响,分析结果表明缓冲距离在300～600m是较为合适的。更多还原

【Abstract】 Geographic information systems(GIS) have been widely recognized and used in the analysis of correlation between faults and landslides. The most common is to establish statistical models based on buffer analysis and overlay analysis to calculate the fault distance and the number of landslides. However, in the process of model establishment, there is such a problem: the statistical model established by using the large buffer distance, its statistical results can be suitable to reflect the correlation between faults and landslides. In order to solve this problem, the faults and landslides in the mountain area of southern Anhui are taken as the research object. The statistical model of buffer distances of different sizes is analyzed based on the Pearson method. The influence of the correlation between faults and landslides is analyzed. The analysis results show that the buffer distance is 300-600 m. It is more appropriate.更多还原
