Traditional analysis of landslide evolution discipline requires particular on-site investigation, which not only consumes a lot of manpower and material resources, but is also very inefficient. With the development of small drone aerial photography technology, a method based on the whole area landslide measurement becomes possible. This paper uses the rapid development of digital photogrammetry technology in recent years to monitor the surface deformation of the Qinyu landslide, and conducts an in-depth study of its evolution. The results show that the evolution of the Qinyu landslide is inherited and different in time and space. The reconstruction of the three-dimensional model greatly simplifies the traditional on-site investigation, and it also provides new methods and ideas for landslide monitoring.

传统的滑坡演化学科分析需要特别的现场调查，不仅耗费大量的人力物力，而且效率非常低。随着小型无人机航拍技术的发展，基于全区滑坡测量的方法成为可能。本文利用近年来飞速发展的数字摄影测量技术对沁榆滑坡的地表变形进行监测，并对其演化进行了深入研究。结果表明，沁榆滑坡的演化具有继承性，时空不同。三维模型的重建大大简化了传统的现场调查，也为滑坡监测提供了新的方法和思路。
