根据延安地区12县1区地质灾害实地调查成果，对调查数据进行统计分析，结合遥感技术和调查实例，对区内主要的人类工程活动与地质灾害发育程度的相关性进行了分析，研究表明：延安地区城镇建设、交通建设与地质灾害的分布关系明显；人口居住密度与滑坡、崩塌、不稳定斜坡的发育数量呈正比，其中与滑坡灾害的关系最为密切；地质灾害的发育在空间上与交通线路体现出相关性，低级别公路建设孕育的地质灾害密度较大；矿产及油气田开发、水利工程也是区内地质灾害发育的重要原因。%According to the Yan’an area 12 county 1 area of geological disasters investigation results,statisti-cal analysis of survey data,combined with remote sensing technology and investigation on the correlation between examples,human engineering activities and the main geological disaster area development degree are analyzed.The results show that the relationship between the development of Yanan urban construction,traffic construction,miner-al and oil gas field development,water conservancy engineering and geological disasters were proportional to the population development;population density and landslides,avalanches and unstable slopes,which is most closely with the landslide;geological disaster development in space and traffic lines reflect the correlation between low grade highway construction has high density of geological disasters;This paper has certain reference value to the work of disaster prevention and land use planning in Yanan area.
