摘　　要：地质灾害越来越成为影响人居和生产生活环境安全的重要制约因素,广东江门市新会区地质灾害类型主要为崩塌和滑坡,采用空间统计与相关分析的方法对地质灾害的影响因素进行定量分析,结果表明:影响新会区崩塌、滑坡地质灾害发生的主控因素是高程、坡度和工程地质岩组,降雨及人类工程活动是重要的外在激发因素。Geological disasters have become an important factor affecting the safety of people's production and living environment.The types of geological disasters in Xinhui District,Jiangmen City,Guangdong Province are mainly collapses and landslides.The spatial statistics and correlation analysis methods were used to quantitatively analyze the influencing factors of geological disasters.The results show that the main controlling factors affecting the occurrence of collapses and landslides in Xinhui District are elevation,slope,and engineering geological rock groups,whereas therainfall and human engineering activities are important external excitation factors.
