地面坡度是反映地形地貌变化的关键因子，应用坡度分析一定程度上可以反映断层的展布特征。本文收集整理昆明市区附近千余份钻孔数据，筛选其中238个钻孔进行钻孔层序分层和数据库的建设，使用ArcScene软件生成研究区地表、海埂组（QhH）底部以及官渡组（Qp’G）底部地层面的三维地质模型。应用ArcGIS软件中坡度分析模块，获得各个界面的坡度图，从坡度变化特征方面对研究区5条主要断层的活动性与分段特征进行了初步探讨。

Land slope is the key factor to reflect the changes of the topography landforms and slope analysis also could reflect the faults distributing features to some extent. We collected thousands of Quaternary borehole data of Kunming urban area and selected 238 boreholes data for 3D modeling. Through the 238 quaternary boreholes data, this paper built up database and established this area 3D geologic model of the surface, the bottom of Haigeng Group (QhH) and the bottom of Guandu Group(Qp3G) using ArcScene software. The paper got the slope maps of the 3 layers using the slope analysis function of ArgGIS software and preliminarily discuses the segmentation of 5 main faults in research area utilizing slope variation feature.
