英文摘要：

Landslide deformation monitoring data is the most significant parameters which can reflect the occurrence, development and evolution of landslide and is also the necessary foundation data for landslide monitoring and early waming. This paper summarizes the basic principles, technical characteristics and application progress of various types of deformation monitoring technology in the landslide deformation monitoring field including both the contact deformation monitoring technology and non-contact deformation monitoring. The analysis of advantages and the disadvantages about various techniques in practical applications are also presented. Meanwhile, the development trend of landslide deformation monitoring techniques are analyzed and summarized in three aspects： application of multi-technology integration, research of new monitoring instruments and data mining of monitoring survey.
